Sleeping with a monitor

how can i get my laptop to stay awake although i close it, so i can use my monitor as my main display?

I have not verified this but I always used to do it this way with my pismo powerbook when that thing was around, and I think I may have done it like this with my 12" powerbook G4 1Gz...
What you do it shut down the mac or sleep it and plug in the external display. Then when you boot it or wake it you have to close the cover relatively quickly as it is waking up or booting and it will detect that you want to use only the external display. Then once the external is goin, you can open the lid and use the keyboard as normal...
hope this helps!

MacBook Pro won't sleep with external monitor

Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you

Hey Renecek,
My first thought was, "Hey, you are using closed-clamshell mode".

Won't sleep with 2 monitors

Hi
My G4 GE will not sleep when I have dual monitors connected.
I have the stock AGP Rage Card with a Sony CRT.
And I have an additional PCI Rage card with an Apple Studio Display.
When the second monitor is connected, the mac will not go to sleep. (I click Sleep in the Apple menu - both monitors go out but the mac is still running).
If I disconnect the second monitor, everything is fine. The machine sleeps normally.
Anybody know why this is? Is it fixable? I've done the prefs trashing.

Hi, IndiGo!.
1. What changes did you make to your Mac before this problem arose? If the problem arose after making a change, it's possible the change is the cause. Is the addition of a "second monitor" the latest change?
2. You wrote: "When the second monitor is connected, the mac will not go to sleep. (I click Sleep in the Apple menu - both monitors go out but the mac is still running)."This implies that whatever graphics card or monitor from the two pairs you specified that is "the second monitor" is not responding to Mac OS X power management commands. The Mac may then be in Doze, vs. Deep Sleep mode.
If the "PCI Rage" card is driving the second monitor, assure you have the correct drivers for such.
Good luck!

Display sleep with dual monitor setup

I'm running a 17" studio display and a 20" studio display as a two momitor setup on a dual G5 2.0. The menu bar is on the 17". Unless I have display sleep in energy saver set to never, the 17" will go to sleep at the interval set in the preference panel, even when the system is in use. So far the only way I've found to get the display back off sleep is to put the computer itself to sleep - keyboard shortcut or by using the power button on the 17" and then wake it up.
I think this only started with 10.4.6. I can't upgrade to 10.4.7 yet - I run Avid Xpress Pro on the system and 10.4.7 gives dongle trouble. I've thrown away preference files, set and reset the sleep parameters. As it happens, I've had to reinstall the system a couple of weeks back, but the 17" studio still goes to sleep when it shouldn't.
The problem doesn't occur if the menu bar is on the 20" cinema display, but that's not the way I want it.
Anyone with the same problem,, or better a suggested solution?

finally found the solution (apple i hope your reading
this as this is a mad bug!)
you need to have the dock on the bottom of the main
screen in order to view the image on that screen.
Wierd, I have my dock on the left side of my main screen... which is to the left of my secondary screen. Perhaps you cannot have the dock in-between screens?
kgelner, how have you noticed the performance of your
card when working with aperture? Im seriously
debating upgrading mine as its just slow and annoying
I find it usable but I'm also only working with TIFF files (my camera is not supported). I am also pretty strongly thinking about going with the X800xt card, which should be at least twice as fast. Some operations (like a lot of Spot & Patch repairs combined with Shadows/Highlights) do make things a bit laggy.
I also have the 256MB version of the 9800, which I think helps with some of the larger images and operations.

Shadow artifacts when waking from sleep with an external monitor.

This problem happens when I have an external monitor connected, I put the MacBook to sleep, and then wake it up with the monitor still connected.
Upon waking, the shadow effects surrounding all of the windows get "corrupted"
The shadows look like TV static at the corners and black streaks along the sides. This effects all windows that were open and all new windows.
I imagine the bitmaps that are used for the shadows get corrupted on sleep for some reason.
I have some non-original ram installed right now, so I'll try reseating it and I'll try putting the original ram back in and let you guys know if it makes a difference.
Has anyone else had this problem?

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

No display after sleep with macmini using DVI - S-video/composite under XP

Hi guys, I have installed XP on my mini. I have CRT TV so I'm using
DVI -> S-video/composite to output to my TV.
The problem is after sleep - there is no display (it's woking only after reset).
I installed the latest drivers from the mac os 10.5 DVD & updated the graphics driver from Intel.
Please help

Unfortunately, no answer, as I'm having the similar problem with a Samsung SyncMaster 215tw and a G4 Mini. It works with the DVI-VGA adapter and the VGA cable into the montor's VGA port. However, connecting with the G$ Mini's DVI port with the monitor's DVI port using a DVI cable doesn't work. I cannot figure out why this doesn't work.
The DVI cable is good and the monitor's DVI port is good, as the connection does work using my friend's Intel Mini's DVI port connected to the monitor's DVI port using the DVI cable.
The monitor is new, too, and otherwise works fine with my other Macs connected with the VGA port. (I've not tried the additional ports as yet.)
Although the monitor is supposed to synchroize automatically, I also tried manually presetting the G4 Mini to different resolutions, but that didn't make any difference. The screen remains black when it should be showing the booting Apple icon.
Any idea what is going wrong here, please, as it sounds as if this same thing occurs with various monitors?

Problems when waking from sleep with display

Okay, so I have a Dual 1.8 G5 with an upgraded ATI Radeon 9800 Pro graphics card that I've had in it for over a year now. I just bought a new monitor, a Viewsonic 22" widescreen LCD to replace the 17" viewsonic CRD I had. Now, i get occasionally some random noise or something when the computer wakes from sleep that disappears most of the time if I turn the monitor off and back on.
Now does anyone have a thought as to if this is a problem with the monitor (i.e. should I take it back) or a problem with the card.
Thanks

Paul Pardue-
How is the monitor connected to the card? Have you verified that all of your connections are secure?
What does the noise look like?

So it looks to me like both displays are being detected. The geometry looks such that one display is on top of the other, but I can change that using an xorg.conf.d config file (e.g. https://wiki.archlinux.org/index.php/Mu … xorg.conf). I also tried using arandr.
The real problem is that the display on HDMI3 just isn't "waking up". The power is on, but it just sits there in sleep mode.
Any help would be great. I might just be missing something simple. Thanks.
Edit: I just saw a short list of window managers near the bottom of the Arch Multihead page (https://wiki.archlinux.org/index.php/Mu … _xorg.conf). I don't see openbox on that list. Does that mean I'm SOL if I want to use openbox with multiple monitors? This page seems to imply that it should work fine with openbox http://magnatecha.com/dual-monitors-wit … nd-xrandr/.

I use XFCE, and when I boot my computer I just run:
xrandr --output DVI-I-1 --auto --output DVI-I-2 --auto --left-of DVI-I-1
I'm assuming if you modify the names appropriately that it'll work too. I have had issues before trying to run dual monitors without taking both outputs off of a single video card (which is what I'm doing now). For example, I had a graphics card with one (VGA) output and a VGA output on my motherboard. But, connecting the graphics card disabled the on-board VGA. So it is possible (I'm not an expert here) that two displays coming off the motherboard may not work for hardware reasons.

Why will macbook pro not go to sleep with Lion OS?

Why will macbook pro not go to sleep with Lion OS?

Test after each of the following steps that you haven’t already tried:
Step 1
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

Thinkpad T440s freezes with 2nd monitor via dock

Hi there - I have a strange problem with my Thinkpad T440s:
Connecting a 2nd monitor directly (VGA) works like a charm, however putting the Thinkpad into the docking station (with the 2nd monitor connected to the dock) freezes the system. Without the 2nd monitor the dock is working fine. When booting with the 2nd monitor connected to the dock, both screens stay black as soon as the kernel loads.
Is this a known problem / any ideas? Can I somehow help fixing this problem?
I know that I'm not the only one since I have found other people reporting this here: http://thinkpad-forum.de/threads/165520 … -und-Linux
They also provided an xorg.log (http://pastebin.com/Qk7nHVwt) which shows nothing suspicious, I guess...

Same issue with my T440p. Happens with VGA, DP & HDMI (haven't tested DVI) on the dock. Undocking unfreezes it. If X is running the X server freezes and consumes 20% CPU, if none is running a kworker process does that. Even with no monitor attached it will freeze when the builtin monitor wakes up from sleep (again, undocking helps).
Here's a stack trace from the frozen X (^C'd while it was frozen from waking up the display, gdb only reacted again after undocking):
#0 0x00007fe972febf87 in ioctl () from /usr/lib/libc.so.6

Edit: "Solved" by returning the laptop. This issue plus the loud (and not well-controllable) fan and the lack of support for the fingerprint sensor (different from previous ThinkPad models, it's from Validity Sensors) just aren't worth the trouble.

[SOLVED] Modesetting with external monitor broken (intel)

After recent updates, modesetting during boot no longer works if an external (vga) monitor is plugged in.
Once it gets to modesetting, both screens go black and I can't tell what happens after that (Might hang, might boot fine I just can't see it…) The external vga screen is black (with very occasional horizontal line of noise), but remains on (It doesn't go to sleep, which it usually does if not receiving a signal).
If the monitor is unplugged during boot then plugged in once the login prompt is reached, modesetting works and running X multihead with xrandr seems to work normally. (workaround until the issue is solved)
Changing from Early KMS start to Late KMS start means the black screen appears later, but it still appears.
Booting with nomodeset works with the monitor plugged in, but means X fails to start with an error message about not finding any screens.
The laptop is an old macbook, with integrated intel graphics card:

Ok, I'm trying to collect information for a bug report, so if people could confirm or correct what I have so far and add any additional relevant information, that'd be very helpful.
The fact that running the linux-lts kernel fixes the issue suggests that the problem almost certainly lies with the kernel.
Comparing the date of my first post with /var/log/pacman.log, I believe the upgrade that first caused the issue to appear was this:
upgraded linux (3.7.3-1 -> 3.7.4-1)
(There is a very slim possibility that I managed to upgrade to 3.7.4 without actually rebooting into the previous kernel, in which case the issue could have been present in an earlier version, but I wouldn't have encountered it.)
So far, the only graphics card affected appears to integrated intel chips:
Intel Corporation Mobile 945GM/GMS(/GME), 943/940GML Express Integrated Graphics Controller (rev 03)
Has anyone observed this issue with a different graphics card? (check the output from entering "lspci" in a terminal if you're not sure how to find out)
Finally, Wittfella found reinstalling from scratch fixed the issue. If someone can come up with a reasonable explanation as to *why* this fixed it (and ideally narrow it down to changes that can be made without reinstalling from scratch if at all possible), then it's possible that it's not an actual bug, so much as a poorly documented change that causes problems upgrading but is otherwise ok afterwards.

Using the GT70 with external monitor and lid closed

I wasn't sure where to post this question.
I have several laptops and use external monitors. I close the lid on the laptops and the display continues to work.
On the GT70, the system shuts down. It won't allow me to use the external keyboard and mouse or display the session.
Any suggestions if there is a configuration option to allow the GT70 to continue to function with external monitor and lid closed.

Yup. This is a windows setting. You need to go into your control panel -> power options -> "Choose when the computer sleeps" and "Choose what closing the lid does"
That should solve the problem. I currently have my GT70 hooked up to a 42" TV and I can close the lid and it stays on and the TV continues displaying as well. No problems. =]

Mountin Lion has trouble with external monitors

Not so much a question as a shout-out. Since going to Mountain Lion, my pretty new (February this year) MacBook has been having no end of trouble with external monitors. I use it a lot with the clamshell closed with two different external monitors of two different sizes, one at home, one at work. It sometimes thinks the one is the other, or if I unplug the monitor in sleep, when I later open the clamshell, the screen stays black and I have to force a reboot with the power button. Never had these problems with exactly the same set-up in Lion. Sometimes it also refuses to find a connected monitor or projector, I have to pull the dangle and put it in again.

If memory serves, one of the 'flaws' with BM's hardware is that it will not convert on-the-fly. So if your sequence doesn't match what the TV is accepting, you get black.
For example, my TV will not accept 1080p, only 1080i, so working in a 1080p sequence would produce no image for me as the BM will only output exactly what's in the sequence, it can't convert my 1080p/24 sequence into 1080i/30 for output.
Now I'd expect your TV would have no trouble accepting a 720p signal but, maybe the above data will lead you down a path of investigation.

MacBook Pro with external monitor and keyboard.

Hello, everyone.
I've tried to find the answer for this question but haven't found a clear answer with my Google search.
My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
Thank you in advance for your answers.
Joseph

Hi Niel,
I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
Thanks!
P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.
