X REALLY slow when external monitor plugged in at boot

Hello all, I am running Kernel 2.6.29.4 with xf86-video-intel 2.7.1-1, Xorg 1.6.1.901 and EXA acceleration (no KMS) on my thinkpad T61 with an Intel X3100. (I keep up-to-date stable.)
Whenever I have the VGA monitor plugged in to my laptop at boot time, when I log in using GDM it takes FOREVER to start XFCE. Super slow motion.
If I wait to plug in the monitor until after X starts, and then type 'xrandr --auto' there is no problem whatsoever.
In both cases, X correctly sets the video mode with no problem. Any idea what is causing the slowdown? Thanks!

No, but I haven't tried in a while since I don't use an external monitor currently. Is it slow all the time, or only if you connect the monitor before X boots? Do you have intel graphics?

MBP Freezes upon display detection when external monitor plugged in

My new MBP (2.16GHz Core2Duo) will freeze up temporarily when I plug in an external monitor (I use a Compaq MV700). This monitor has served my two previous Powerbooks well, so this seems somewhat anomalous.

Is it just this display or all displays? You might want to try resetting PRAM and NVRAM…

Hey my internet is really slow when other people use it.
Also it is a problem when i'm xbox live, i'll be playing a game and when someone else in the house is on BBC i player, it skips like mad and its so frustrating to play on, in fact its unplayable.
I just want to know if there is a way to fix this,
I have BT broadband and i have the black hub.
I have no ideas about computers and internet so i really dont know what to do about this!
any help would be much appreciated, thank you xx

Mac mini VPN headless, slow graphics performance when no monitor plugged in

I am using a Mac mini, headless, with no monitor, keyboard or mouse, via VPN from a Windows machine over a LAN. Everything works fine and setting everything up was a breeze. However, something very odd I noticed was that if my Mac mini does not have a monitor plugged in to its video output, the rendering of the graphics over the VPN is very slow. It is most noticable when hovering over the dock and activating the animations etc, though it is noticable all the time. It's so bad that it would be IMPOSSIBLE to watch a video clip or simple animation. It's as though frames are being dropped. Now, this can be immediately fixed if a monitor is plugged into the Mac mini and turned on, and the VPN to the Mac mini from my Windows machine works flawlessly and the graphics are rendered perfectly, with little to no delay or frame skipping.
I have a hunch that the Mac could be disabling some kind of graphics acceleration when the monitor is not plugged in, but I am not a Mac expert by far, this is my first Mac experience. It was purchased solely for the VPN and headless use, so if I can't get it working properly, it's a waste.
Note, I have tried several VPN client/viewer combinations and they do not change the situation.
Thanks in advance.
Message was edited by: HopkinFrog
Also, when I try to use the remote with the Mac mini (pressing the menu button), over VPN with no monitor attached to the machine, I simply get a white blank screen until I press the menu button again.

I must have been HALF ASLEEP when I wrote this.
I do not mean VPN, I mean VNC!!. Sorry for the confusion.

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

External Monitor plugs in, then goes dark?

Hello-
I have an early-2008 15" MacBook Pro. I purchased it in June of 2008.
The issue I am having is when I am using an external-monitor as a second display. I use a DVI->VGA converter for my external monitor. When I plug it in, my notebook will recognize the external display, it will format the resolution and all, and it will even show the extension-desktop on the external. However, after about two seconds, the external will return back to black (although it does NOT display "no input" like it would if it was turned on with nothing plugged into it).
Any suggestions?
I really appreciate it.

MacBook Air is getting hot when external monitor is connected - restart solves the problem

I have a two weeks old Mac Book Air 11" (128GB / 4GB / i5). Sometimes when I connect it to my external monitor, the FAN is getting loud and the MacBook becomes very warm on the surface near the "F3 button". The activity monitor says CPU is at 0-1% and there's no process that causes any CPU load (I switched to "show all processes" of course). Nevertheless something makes the Mac becoming hot. A simple restart while the external monitor is connected solves the issue completely, temperature and fan speed are instantly decreasing. Is this a issue related to the graphics driver? For me it seems the behavior is caused by the graphics processor rather than by the i5 CPU as activity monitor does not show any process causing high CPU load.
Known issue?
Thanks!

I was runnig into the same problem. Plugging in to the apple 23" display at work worked well, but when I plugged in my Dell 23" at home the fan started being noisy...
ALTERNATIVE SOLUTION: it seems to me that putting the air to into SLEEP MODE and back solves it as well!!
I will confirm later on.

Aero switches off when extern monitor is rotated by Nvidia ControlPanel

Please see subject
Aero works fully when desktop is expanded to the 2nd monitor in normal view.
any workaround ?
Message was edited by: mhoffmann
sorry, I forgot to mention my hw: Satellite a100-02b ( geforce go 7600 )
.. and when I reboot Vista behaves a bit strange.
a few seconds all seems ok but then it sets back the external monitor to 16-bit colour and minimum Vfrequency ( 60 HZ )
and a message pops up that the "Desktop windows manager" has been closed due to a problem.
Is this perhaps because..
1) It's an old CRT, not specially known ( standard pnp-driver )?
2) the vista capability of the graphics adapter is not sufficient in this configuration ?
I heard somewhere that there is a switch in the registry, that disables the dwm.exe's test, whether the hardware is
able to support the aero-technologies. would that be a way to fix that ?

Hi,
and thanks!

No I've EXPANDED the desktop to the 2nd monitor. In normal view Aero works right then on BOTH monitors.
Only when I rotate the extern monitor this problem occurs.
I think, that this special configuration is a bit unique ( but very comfortable to work on )
and therefore not foreseen ( eeh, sorry for my english ) by the programmers of the drivers or
the dwm-team at MS.
ok, when I add the 1280*800 of the laptop screen and the 768*1024 of the CRT
I end up at 2048*1024 ( the unused area included )which is quite near to the absolute maximum of 2048*1536 the graphics adapter
supports on ONE monitor at all. Perhaps that's just too much...
on the http://support.toshiba-tro.de/kb0/TSB7101O90002R01.htm you mentioned, the limit for aero with my 128 MByte VideoRam
would be 2.304.000 pixels - but only when one monitor is in use. There's no information about multi-monitor use.
so what, Aero is not that important, but when I have some time again, I will experiment a bit...
Ciao !

All opened applications crash when external monitor is attached in to MacBook Air 2013

I experience crashes (automatical restarts) of all the applications when I attach external monitor. I have MacBook Air 13-inch mid 2013 and OS X 10.8.4 in spanish. The crashes are regular but not every time I attach monitor.
Does anyone experience the same?
Thanks,

Lenovo spkrs work only when external spkrs plugged in

Arch runs great on noobies Lenovo 3000 n100.
Streaming audio and system sounds work fine only when external spkrs are plugged into headphone socket.
Onboard spkrs can be heard along with external spkrs together. I have tried every combination of Gnome-volume-control sliders and mutes to hear onboard spkrs by themselves but no luck. It's not a big deal as the laptop is always on my desk but I'm just curious if it can be fixed as I am not experienced enough yet.
Thanks

Enabling internal when external speakers plugged in

is there a way to enable the internal speakers when i have external speakers plugged in on my 24" iMac??
i want this cause i use a Bose Cinemate® speaker system and it powers off after inactivity/no sound ... so then I don't hear alarms etc ...
btw i've asked Bose and they say there's no way to disable their power off timeout ;-()
TIA

Hello mate
I have a similar headache wanting to connect bluetooth speakers as well as plugged in speakers to play itunes in 2 rooms at the same time...nigh on impossible and is still a nightmare- however a solution that may work for you is this..http://www.versiontracker.com/dyn/moreinfo/macosx/18611 - its a piece of audio software called audio highjacker that allows you to play external and internal speakers at the same time. It wont work for me due to the latency or delay to my bluetooth - it plays the same tune a second or out of sync - so in one room they are just into the chorus while the other room they are still on the verse!!
Anyway download Audio highjacker and go to itunes (or whatever audio you want to highjack) open audio jack and click the application in its menu window. make sure source type is 'application' and mute is off - then click highjack - then 'click here to insert effect' choose 4fx and then auxillary device output - this will bring up a menu where you can choose what you want playing thru the other speakers or internal - this is from memory so apologies if its a little inaccurate - but this will play internal and external speaker at the same time - although not perfectly sychronised
hope this helps
cheers

Premiere PRO CS4 really slow when playing back AVCHD

Hi,
I'm trying to edit some AVCHD (full HD 1920x1080p) but the playback in Premiere PRO CS4 is really really slow. The quality is set to Draft and even resizing the window to 25% keeps it slow.
So I decided to give it a try upgrading my computer. But... what should I upgrade to improve playback and edit my videos smoothly?
I have this PC specifications
- DualCore AMD Athlon 64X2 6000+ (3.0 GHz)
- 2 GB RAM DDR2-800 (Kingston)
- 1 TB WesternDigital 7200 rpm Hard Drive
- nVidia GeForce 9800 GT (1 GB Ram)
Any recommendations would be appreciated.
Thanks

I need to admint that I made a huge mistake when I got the HD camera in my hands and I started shooting and watching it on a HDTV and it was nicely recorded. But oh surprise!, when I tried to watch it and edit it on my computer it was a nightmare.
Yes, that was what I was alluding to earlier on. It seems to be a good format, but requires an investment in gear to smoothly edit it. I almost feel that there should be a warning label on all cameras, that use it. At least it IS editable, unlike some other formats.
what a nice I/O sub-system article there, thanks for that
I agree, and that is why I try to tell Harm "thank you," whenever I can. He actually did three along the same lines. This was #1, IIRC, with a more generalized followup on the hardware beyond the I/O, and #3 was his setup details for 64-bit OS. All three are well worth reading. He put a lot of time, thought and effort into those. First thing that I did was publish links to each on several Video production fora.
Good luck, and please let us know how your new rig handles the AVCHD material. Before you get too far into things, Harm's other two articles might be of use too.

MBP display turns off when external monitor is attached

Hi there,
Over the last few days I have been trying to get Windows 7 to work with an external monitor. I am running a Mid 2012 15" Macbook Pro with a Nvidia GeForce GT 650M GPU. I sucessfully installed windows 7 in bootcamp and everything worked flawlessly until I try to connect my monitor with the mini displayport via a VGA <-> Displayport adaptor. When I connect it the monitor powers on, with the windows desktop and is responsive but the mouse dissapears and the MacBook Pro's monitor turns off. The mouse is still useable but invisible, so its very difficult to do anything. I have tried to update the Nvidia drivers as well as trying everything I can think of and haven't been able to find a solution. Has anyone else out there exerinced this, or found a solution?

Okay, so a little update. I have determined that the problem is the nvidia driver. When I roll back the driver to the "Microsoft Basic Display Adaptor" driver and connect the monitor then it behaves as excpected. The external monitor isn't detected and everything continues to work properly.
So is there anyone out there who is running a Mid 2012 15" MacBook Pro with an external monitor in either Windows 7 or 8.1? If so please let me know what your setup is and what driver version you are using. This is driving me crazy. Thanks.

IChat disconnects when external monitor connected to Macbook Pro.

Downloaded latest OSX patch last week (Thunderbolt patch). Now, when connecting my HP external monitor to my Macbook Pro (2011), iChat will only stay connected for 2 to 3 minutes. If I disconnect my external monitor, iChat will stay connected all day long. This just started last week after loading the latest SW upgrade. Any ideas?

Hi,
I am not going to be much use here.
I don't have a computer with Thunderbolt.
The computer I do run a second screen on is a G4 running Leopard and in the Energy Saver there is no setting for the second screen to be set independently than the main screen.
I think it may pay to ask again in the Lion Forum Community.
