Chromium causing monitors not to sleep

I have a fully updated system as of Feb 27 PM. Coinciding with a recent upgrade to chromium (looks like it was feb 21st to version 25.0.1364.97) my monitors stopped going to sleep after the set time. I use KDE, and going into the power management settings its set to switch off monitors at 15 minutes. After much trial and error, I have discovered that if I leave chromium open and running, my monitors won't sleep, even if I close down all tabs and leave it on just the empty tab. Simply closing down chromium will allow dpms to work correctly.
I am wondering if anyone else has noticed this issue, as well as if anyone had ideas on where to start fixing? I've searched and haven't come across any other people complaining about this.

so i completely purged my system of chromium, including what was in my user folder. monitors sleep just fine. reinstalled, and without it running still sleeps fine. as soon as I open chromium up, it won't again. I then installed chromium-dev (vers 27 in aur), and using the same account (meaning same plugins, etc), monitors sleep just fine.
I am fine using dev for now; looks like for whatever reason v25 is causing me issues. If nobody else is seeing this, we can just chalk it up to me being crazy ;-P However wanted to get a discussion going in case others were noticing the same thing.
frank604, i'm not using any apps/scripts like caffeine (I actually had to google it to see what you were talking about). I've always wanted my monitors to sleep, because I leave my system on 24/7 (media server as well as desktop).

Monitor Not Going To Sleep on Mac Mini Server With Lion

Summary: I am attempting to configure a Mac Mini Server that runs OS X Lion. This machine was originally shipped with OS X Lion; it is not an upgrade. My current specific problem is that my Viewsonic VX2835wm monitor will not go to sleep when the minutes setting on the Display Sleep setting for Energy Saver has been reached. Instead, the screen goes blank for a couple of seconds and is replaced with a blank blue backlit monitor. (Ironcially, the display sleep menu cautions: "Never letting your display go to sleep may shorten its life".) I very much want and need the ability to have my monitor go to sleep so as to save energy and to extend the monitor's life for as long as possible.
Additional Background: I have had a couple of calls with Mac support and they have been unable to tell me whether this is a "design feature" or a flaw in the Lion OS because they have had no similar reports and they do not have the latest hardare available running Lion Server to test to see if this happens with other monitors. (They also, of course, don't have the VX2835wm monitor.)
I do, however, know the following:
(1) My HDMI monitor is connected to my Mac mini via a DVI KWM switch (ATEN CS1784) such that the HDMI output from my Mac is converted to DVI (using the DVI to HDMI converter that came with my Mac Mini) and is then run through the KVM and then converted back to HDMI (using a full pin DVI to HDMI cable). However, I have tested the monitor with a straight HDMI to HDMI cable running directly from the Mac Mini to the monitor and it has not changed anything.
(2) The Lion operating system correctly recognizes (in Hardware / Displays) the model of my ViewSonic monitor.
(3) I have a MacBook Pro running Leopard (OS X 10.5.8) that is connected to the same monitor through the same KVM switch (by way of a BookEndz docking station) which properly shuts down the monitor when there has been no activity for however many minutes are set in the Display Sleep setting under Energy Saver. (Indeed, all I want is the same functionality on my Mac Mini that I have enjoyed for the last two years with this MacBook Pro.)
(4) When fully connected to the KVM, if I switch from my Mac Mini to my MacBook Pro and my Mac Mini display goes to sleep while I am working on my MacBook Pro, when I switch back to the Mac Mini, my monitor backlight will be off (and the power light will be standby yellow rather than the blue on) until I wake my computer up by touching the mouse of keyboard. I wonder if this may mean that the Mac Mini's signalling of the change in status from on to standby is somehow dysfunctional.
(5) Shutting down the server functions (and other open applications) has no effect.
I would greatly appreciate feedback from anyone out there running a Mac Mini with Lion regarding whether or not their monitors go into standby mode when the Display Sleep time is reached (please note whether or not you are running the Server or Client version, whether or not it is a new install or upgrade, and what monitor you are using).
Thanks in advance to anyone who can help.

No, I didn't solve the problem. The monitor still goes to sleep with WIndows but not with my Mac Mini. About 8 months ago I basically wore out the power switch on my monitor so I bought a wireless power switch to shut it off at the outlet. The VX2835wm monitor itself is now starting to fail as well-- a couple of times it's gone through a weird sequence of flashing screen colors on power up and ended up in an overscan mode (that took me for ever to figure out how to fix). I have decided to replace my VX2835wm with a Dell u2412m once it fails for good partly because I really want to keep the 16:10 resolution (very hard to find these days) and partly because I want to see if a different make of monitor will go to sleep properly based upon my Mac Mini power down settings.

Monitor not going to sleep when close my lid to MacBook Pro

Hi. I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more. Please help.

Sounds like the system is going into Clamshell mode. Here's some info on that mode.
One workaround would be to disconnect line voltage as that's required for clamshell mode, there may be others.

Monitor not recognized by Mac anymore?????

Hi
This is big and what is APPLE doing to solve this issue??
I just copy some posts from the forum to show how big this issue is, there is 8 more pages with the same problem, and i am one of them!!!!
HELP!!!! WE ARE FREAKING OUT HERE AND NEED A SOLUTION!!!
Yes, me. I have an HP w2207 who worked with my 3 y.o. old MacBook (OS 10.4.??) via the DVI-port flawlessly. Then bought a brandnew MacBook Pro with 10.6.X and the external monitor stopped being recognized. It works now that I have changed the connection to the VGA-port of the monitor (and bought yet another adapter for the MacBook Pro) but the quality is not what I'm used to.

Yes. I've tried 7 different Macs including a MacBook Pro with Snow Leopard (10.6.2) and my external monitor doesn't work with it either.
For me here's a recap:
Installed SL on a Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #1 and now that input no longer works with Mac computers.
Reinstalled 10.5.8 on the Mac Pro and HDMI #1 still didn't work, so I plugged the Mac into HDMI #2 and it worked.
Reinstalled SL on the Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #2 and now that input no longer works with Mac computers.
Since then, every device (PCs, DVD Players, Video Cameras, etc...) I connect to either of the HDMI inputs work fine. However, neither HDMI input works with ANY of the 7 different Macs (regardless of OS version) I've tried, except for a 10-year-old G4 running Panther or Tiger.
The monitor had previously worked with the MacPro (HDMI input #1) and a G5 (HDMI input #2) for almost 2 years.
When I plug the MacPro into any other monitor via HDMI, it works fine. Same thing with the G5.
My theory is still that the installer for Snow Leopard somehow made my monitor's HDMI inputs incompatible with Macs. I'm so frustrated that I'm ready to buy a new monitor, but since there's no guarantee that a new monitor won't be adversely affected by Snow Leopard, I'm still dubious.

Another "me too" post...
Not sure exactly when it stopped working (since I don't use it every day) but my Viewsonic VX2455wm stopped working with my MacBook recently too. Checked with another MacBook (six months newer than my Late 2006 model) and that exhibited the same problem. Both machines have fully patched Snow Leopard installs. Both started with Tiger. Mine is regularly connected to the external monitor, the other has never been connected. I'm connecting using a DVI cable and a mini-DVI-DVI adapter.
The monitor appears to work correctly. I've checked with a Windows laptop connected on the VGA port. I want to test with another DVI-enabled machine to see whether or not its the cable.

Hi Guys
I have the same problem with my new Dell 2209WAf. It worked fine before i changed from L to SL.
I didn't know what happened so i have spend hours and hours to resolve the problem.
Hours with Mac support and friends didn't change anything, i still cant make my Dell to work, or show up in preferences. I am working as a photographer and this issue is a real problem.
I just heard from Mac Support that Apple is working on it.....well, doesn't help us with the problem today.
So Apple, DO SOMETHING ABOUT THIS! NOW! this problem should NEVER showed up, this is something you should have fixed before telling all the Macers to upgrade!!!

Experiencing the same issues. However, on bit different hardware.
I'm using the XLR8 ProView USB input devices. Using these devices on a mixture of 10.5.8 and 10.6.2 systems (2 MacBooks, 2 Mac Mini and 1 iMac).
I can confirm the following:
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.6.2 no video is sent to the mini-DVI device (inputing into the XLR8).
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.5.8 video is sent to the mini-DVI device (inputing into the XLR8).
Let me also state, that the mini-DVI port on the Mac Mini's do work. They have been connected to 19" monitors and working without issue. Today, the mini-DVI devices were replaced with minidisplay port devices, which are use in conjunction with the mini-DVI ports.
It would appear, in my case, that the problem is that the mini-DVI port on both the MacBook and Mac Mini, running 10.6.2, as a secondary display device is not operating properly.

Same problems here. I reloaded OS 10.4.6 which is what shipped with my MBP1,2 17" 2.16 Intel Core Duo 2GB ram and after installing that, i was able to select 1920x1080 for my external HP w2338h, DVI-VGA, never been able to connect DVI-HDMI. On SL, the max rez I was able to "use" was 1600x1200 which looked horrible. So this leads me to suspect that this must be an issue with SL.
I spoke with Apple Tech support on Sat and was no help. The only suggestion was that I take my MBP and Monitor to the Apple Store. Those of you who are fortunate enough to live in Chicago in the winter, then you know that option really isn't that feasible, it is but just a giant pain.

I have an iMac 9,1 Intel Core 2 Duo that I bought last June. It came with Leopard, but I upgraded to Snow Leopard. Currently, it's running 10.6.2. My HP w2207 Widescreen monitor works perfectly with it using the DVI port on the HP and the mini-display (not mini-DVI) port on the iMac.
However, I just bought the top-of-the-line iMac 11,1 Intel Core i5 QuadCore three days ago and it crashes nearly every time that it wakes from "sleep" when the HP w2207 is connected to it. It doesn't even recognize that the w2207 is connected to it. Additionally, when the w2207 is connected, it (a) looks terrible - very dim and very granular, and (b) causes the iMac QuadCore to operate very sluggishly. When I disconnect the HP w2207, the iMac QuadCore is lightning-fast.
Much like my older iMac, the QuadCore is running 10.6.2 and I'm using the mini-display port.

Another me too post. I have a new 17" MacBook Pro with 10.6.2 installed. Trying to connect to an HPL2245wg - sometimes it works flawlessly - other times not at all. Some mornings I spend 30 -40 minutes rebooting, unplugging and plugging the monitor, Detecting Displays, changing the Graphics Card (Energy settings) - all to no avail. Very, very frustrating Apple - please figure out what is going on with this issue....and get it fixed!

Wow, me too. Did a minor software update (apple released it) last night, got on this morning and BANG - my main 24" Dell display is NOT working.
This is ******, apple have surely f**ked up here. It's never had a hitch, ever, since i bought it 9 months ago.
We are all reporting the same thing - software update, and then no working external display...

I seem to have found a fix for myself. I was having terrible issues with the screen blinking and flickering constantly. I tried to reset the SMC with everything unplugged and the computer would not reboot at that point on it's own which led me eventually to reinstalling SL.
Reinstalling SL is quite painless actually as it installs on top of your profile. After reinstalling I ran software update which installs the cumulative upgrades. Now I usually don't have any problems but must follow the instructions to run in clamshell mode to the letter.
After a week of running in clamshell mode I started having an issue with the dock not lining up so I put the computer to sleep, disconnected the monitor and restarted with nothing connected. After that, followed the clamshell mode instructions again and have been working fine again all week.
I've also disabled my screen-saver, and deleted the windowserver preferences as part of my debug process but not sure if that has contributed to my new found stability.

Me too. I have a MacBook Pro 2,2 running the latest Snow Leopard 10.6.2. After I have installed yesterday's security patch it does not recognize external displays on the DVI port any longer. Tried it with a 23" DELL at the office and a 23" Samsung at home. Both have worked without any problems for years.
I am curious to learn how this behavior is related to security...

All-in-one 6830 printer Does not enter sleep mode when connected to a phone line

HP staff help. HP all-in-one printer 6830 does not enter sleep mode when conntected to a phone line via 1-Line jack. The Firmware is PNP1CN1521AR. On August 1, 2015, I purchased an HP all-in-one 6830 printer and upgraded to firmware PNP1CN1521AR.When a phone line is connected to 1-Line jack of 6830, the printer will no longer enter sleep mode and the display remains on indefinitly.Removing the phone connection either from the wall outlet or from the printer causes the sleep mode to work correctly again where the control panel display turns off after 5 minutes (or optionally after 10 or 15 minutes).This problem was previously reported by a user and has not been resolved, see:http://h30434.www3.hp.com/t5/Other-Printing-Questions/Sleep-mode-of-Officejet-Pro-6830/td-p/4772182 The user did not receive a resolution to this problem according to the thread.
There seems to be a 6830 printer firmware or hardware problem causing this. HP should be able to confirm this problem on 6830 easily.
Please advise ASAP.
Thanks

It's a regular analog phone line. I've tested it with other phone lines. No difference. I have another all-in-one printer which works fine (goes to sleep mode) when plugged into the same phone line.
The 6830 works ok in other aspects. The only problem is the sleep mode. Any 6830 with the firmware I mentioned should replicate the same result, regardless of anything else. The previous firmware to PNP1CN1521AR also created this problem according to the original report of this problem by another user.
I'm sure there's a bug in the firmware. A subroutine in the firmware monitoring the incoming fax ringing, mistakenly, sees the voltage across the phone jack pins as an event and wakes up the printer instantly even though there's no ringing. As the previous user also suspected, there seems to be an error in the phone line voltage threshold used by the firmware. The present firmware always sees a ringing at the phone line which causes it to never stay in sleep mode.

MacBook Pro overheating when monitor is in sleep [weird]

Hello everybody,
this is my first post here but I am a long time Apple user (from 1995 until today).
Last summer, in August, I bought my new MBP 15" with non-Retina display, mid-2012 series which presents a very strange issue.
I investigated a lot on the problem, trying everything, without coming to a solution, unfortunately.
I think I will contact Apple also via Bug Report website, because I think it's a software bug. I'd like to hearing from you, as well.
Users' experiences are often more useful.
The thing is quite simple to reproduce: when I put the monitor(s) to sleep, doesn't matter if only the integrated one or using also the external display attached to the Mac, the GPU becomes HOT, let's say hotter than when using the Mac normally. Isn't it strange?
How do I measure the temperature?
There are many softwares. I use two: Temperature Monitor and iStat Pro, which is a widget for the Dashboard.
I also use my hand!
If I go away from my desktop and leave the display going to sleep, or if I put it to sleep manually using a hot corner (it's the same, no difference), when I come back and touch the top case in the zone corresponding to the processor and the GPUs, it is uncomfortably hot.
When I use the MBP normally, like now, writing this post, with fifteen applications open (among which Photoshop) in the background the GPU is at only 48° and the top case slightly warm.
When I come back from sleep the sensors display temperatures that go from 60°C to 80°C !!!
It's absurd. Everybody knows that high temperatures are not healthy for electronic components and batteries.
I decided to investigate deeply, looking also into the logs, and I found, in /var/log/system.log the following excerpt just after coming back from sleep mode with the GPU working in some mysterious way:

Then I booked an appointment to the Genius Bar, in my nearest Apple Store in Rome.
First time, after explaining the issue, they changed the fans (...).
No way, it didn't work (I had my doubts from the beginning it should do, anyway).
Second time I booked, they resetted SMC and PRAM (NVRAM), and gave me the MacBook Pro back.
It didn't work. I did the reset before going to the AS, by myself, at home.
Third time I booked, suspecting a hardware problem, they changed the whole logic board.
It didn't solve the problem.
I tested and reproduced the issue with the lastest release of Mac OSX, 10.8.3, with a clean install and no third party softwares installed. It happens not everytime the display goes to sleep, but almost everytime.
I also have done all the firmware updates, every time they came along in Software Update application from August 2012 since today.
I really don't know what else I can do, except writing to Apple Bug Reports and hope they read me and work on this.
Moreover, to understand if it's an issue related to the Intel HD Graphics 4000 card or to the NVIDIA GeForce GT 650M one I found and installed a simple software, gfxCardStatus, which allows you to bypass Apple automatic switch feature and choose manually which card to use.
I noticed that only using the most powerful card, the NVIDIA GeForce, the MacBook Pro becomes hot when the display is left alone and goes to sleep after the interval set in Energy Savings options.
Disabling the screensaver doesn't change anything.
Changing the period after which user's password is asked after waking the Mac from sleep changes nothing as well.
Useless to say, I need to leave my Mac turned on, because sometimes I have to access to it from another machine, and I also want to save energy and the life of my monitors putting them to sleep when I don't use them.
Any ideas or suggestions?
Thanks in advance for your attention so far.
Daniele

The Zendock simply bunches the different normal plugs together. So there's no way for the MacBook to detect that it's being used.
I don't think I've seen a dock in recent times that does what you want it to do.

HP Monitor going to sleep on start up

Ok, I've dealt with this problem long enough. I have an HP pavilion Elite, hpe 400f. Monitor worked great on it, then one night while I was checking my email, the picture went scrabled, and ever since I am faced with a "Monitor Going to sleep" error on start up. I can not get into my settings or do anything.
It does not work on other working monitors, I tried a whole new set of cables and when that did not help, I went and bought a new graphics card. That did no good either. But I can not install the drivers until I can actually see how to do it.
So what now? Nothing HP told me works. I am about to go crazy with this. I've begged HP to help me for a year off and on to no prevail.
Can you PLEASE help me?
This question was solved.

HP w2338h monitor not turning on!!!

my HP w2338h monitor is not turning on. My computer is on, blue power button, screeching noise, the whole enchilada. I shook the mouse, clicked aimlessly, then tapped the space bar until the speakers told me to stop. I pressed the power button on the screen. It turned on, and said "monitor going to sleep". Then shut off again. Because the screen was off, Sadly, I had to turn it off with the button on top of the computer ( If you don't know, that is extremely bad for the computer). It didn't turn off. I haven't tried turning the power strip off, and I don't want to, but it seems like my only option.
If it helps, I have an HP Pavilion p6387c, product number #VT650AA#ABA, and an HP w2338h monitor.
PLEASE HELP

Hello Herobrine13922,

I understand that you are getting "Monitor going to sleep" message when you turn your computer on. I would like you to hard reset your entire computer by unplugging it from the power bar and from the back of both the computer and the monitor. Then hold the power button on the computer down for 30 seconds. When you are done that do the same for the monitor. Once this is complete plug them back in and start up your computer.
Please re-post if you still require additional support. Thank you for posting on the HP Forums. Have a great day!

Hpw2338h Monitor is a sleep

The monitor is a sleep so I can not get on computer

Hello Dar1964,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that your HP W2338H Monitor has gone to sleep and will not wake up. I would try a hard reset on it:
Step 1. Unplug the monitor from the wall and the back of the monitor
Step 2. With it unplugged hold down the power button for 30 seconds
Step 3. Plug the monitor back in
If the issue persists try the monitor on a different computer. If it persists sill the issue you are experiencing appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.
I would like to thank you for posting on the HP Forums. Have a great day!

HP Pavilion, Monitor going to sleep error

When i start up my HP Pavilion, It shows a screen with no vga signal, and then it says "Monitor going to sleep" I do not know what to do? Please help.

I am having the same problem where my Desktop turns on, nothing comes up on the monitor and it goes to sleep fairly quickly, and the fan just keeps running in the tower and is louder than normal. The keyboard does not seem to be responsive and I checked to make sure my monitor is working. How would a bad graphics card make the fans keep running like that?

10.9.1 external monitor on hdmi sleep issue

Hi,
I have been lately having issues with my HD LG LED monitor that I have connected to my macbook thru HDMI.
The monitor goes to sleep and does not wake up at all. The screen stays blank - even after rebooting the laptop or waking it up.
My open windows in the monitor stay in that workspace and can not be accessed on the laptop screen.
I have seen flickering issues on my monitor in the past but thought they were due to static or some emi.
The monitor was working great with the Mavericks update as well so I am not sure what changed in between
The monitor works fine with my Windows notebook
Any pointers would be great!
Thanks,

2207H Monitor Not Displaying

I downloaded the Windows 8.1 update and installed it. During the install though it restarted several times on its own and eventually when it came on the computer was running but there was no image on my screen. I ended up taking it to geek squad. They removed my graphics card (nvidia geforce 640gt) and then plugged in their monitor to my onboard graphics and you could see the display on the monitor. I took it home, plugged my monitor in the same way and it only ever says "No signal, monitor going to sleep". After messing with it, putting the graphics card back in, taking it back in, I still was not getting a display. I know the monitor is working though as I have plugged it into my laptop and it displays immediately without issue. I also know that the onbaord graphics for my pc are working because I went and bought the cheapest monitor Walmart had and plugged it in and it's working fine. I tested it with the nvidia card and it gave me the same no signal issue as the other, but on the onboard graphics it works.
How is it my hp monitor isn't working on my pc but is working on my laptop, especially since my pc is also working properly and displaying on another monitor? Any ideas?
Also, since getting the second monitor that will display I checked my drivers for updates, I ran the Maintenance, I scanned it with a malware remover and with norton, I updated all my apps in the store that had updates available, and I re-downloaded the Windows 8.1 update and it installed properly this time.
The pc is a pavillion p7-1410 (i3 intel core) and the monitor is a 2207h 22in flat screen.

Hello @melmiller,
I understand that your HP w2207h 22 inch LCD Monitor worked until you installed the Windows 8.1 update and now will not display on your HP Pavilion p7-1410 Desktop PC yet it displays on your laptop. I suspect that you are looking at a drivers issue. I am providing you with some things you can try below to fix this:
***Be sure to stop the steps as soon as you have the problem fixed!
1. Check the cables running from your computer to the monitor and make sure they are properly secured.
2. See if you can boot into Safe Mode. If you are unsure of how to do this you can use the HP Support document: Windows 8 Safe Mode.
***If you are able to get into Safe Mode uninstall and deleted the graphics drivers and go and download and install GeForce 340.52 Driver for your graphics card.
3. Rollback the Windows 8.1 update and ensure that your graphics drivers are updated before you run the Windows 8.1 update again.
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!

Program windows will rearrange themselves when monitors are in sleep mode - how to stop windows switching screens

iv got 3 screens on one card via display port adapter and a 4th on a second card so as to have a 1 on top of three setup.
the computer itself does not sleep as I have servers running but I have the screens set to sleep after 10 mins.
for the longest time all screens would go to sleep and wake with no issues... in the last few months 2 issues arise.
1. after the monitors go to sleep and in no consistent time 1 monitor wakes enough to show the backlight but no display... wakes ok and sometimes screens dislocated.
and
2. when the monitors come out of power save / sleep mode some of the windows I had open will have been moved to different monitor like the monitors have been unplugged or "detected" numbers have changed and I have seen the number
change a few times as well but not always.
I say some because I have 4 windows open on my left most monitor and 2 of them end up on my right monitor after the glitch.
sometimes the stuff on my center bottom {main screen} will end up on the top single monitor.
no rhyme or reason... some days no issue at all wake up and all is where it should be and all screens slept all night
most often this issue happens at night or after a long sleep session short sleep sessions and it does not happen.
for all the tech info
ATI 5750 and 5770 running in xfire mode w/ 1displayport to DVI / 1 HDMI to DVI / 1 DVI.
and ATI 5450 for the top monitor
windows 7 x64 / 8 core AMD8320 / 16 gig mem.
latest video drivers...
any info?
I'm a tech and even iv been scratching my head for a while on this one
thnx in advance for even reading to see my problem
thnx even more for an answer...lol
2.6 quad core - 3 gig ddr2 - 2x x1550 ati 1 pcie 1pci - 3x 500 gig hd 1 320gig 1 250 gig 1 200 gig

kinda yes i added a second video card as a slave in a crossfire setup
iv had this same setup before and have switched a few times with minor issues that always got solved with driver reload
and for some reason in this final setup this is the only thing still messing with me.
some days wake up and all is correct on screens and all screens are asleep
next day #3 screen on far right will be awake and stuff from #2 middle bottom screen is up on top.
iv tried reloading drivers... iv tried older drivers and beta ...
have tried removing all info related to ati drivers and amd catylist and all that good stuff using their special removal tools...
the event viewer keeps giving this but i don't see a connection
i wish i did but im lost...
The Peer Networking Grouping service depends on the Peer Name Resolution Protocol service which failed to start because of the following error: Overlapped I/O operation is in progress.
and
The Peer Name Resolution Protocol cloud did not start because the creation of the default identity failed with error code: 0x800703e5.
and lastly something about Schannel
The following fatal alert was generated: 43. The internal error state is 252.
everything else is basic stuff
thnx again and crossing fingers

Imac not auto sleeping

I'm not sure what is keeping my imac from auto sleeping. I have all the programs closed except dashboard and finder and my preferences are set to put the machine to sleep after 10 min. My monitor goes to sleep but not my machine. I am able to put my machine to sleep manually. Any ideas?

Try resetting the SMC, it controls things like sleep.
