[Ubuntu-x-swat] [Bug 438000] Re: [i945gm] [karmic] X servers hangs when settings up dual monitor config
*** This bug is a duplicate of bug 419328 *** https://bugs.launchpad.net/bugs/419328 I am having the same issue with a Dell Mini 10 (Model 1011), Atom N230 and GMA 945. I successfully, and without any effort, had Compiz enabled while driving both the LVDS at 1024x576 and the VGA at 1024x768 right of LVDS in 9.04. Today I upgraded to 9.10 via update manager and now have this same issue. Combined width is 2048 which is the max texture size (width) for the 945 chipset. This may not be a bug, but is most definitely a regression because I have lost functionality over a previous version. As mentioned in the other bug, success can be had by arranging the screens vertically: 1. Switch to Metacity (Desktop Effects set to None) 2. Attach external monitor 3. Open Display Settings 4. Arrange external Below LVDS 5. Set proper screen size for the VGA (in my case it's actually 1280x1024) 6. Turn Compiz back on (Desktop Effects set to Extra) This arrangement nets a virtual resolution of 1280 x 1792 which falls neatly inside of the accelerated buffer limit of 2048x2048 on the 945. The problem is, as mentioned, this is a regression from 9.04 (which did let me arrange them side by side) and is spatially difficult to maintain as I don't rest my netbook on top of my monitor as the arrangement seems to make me want to feel. -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 438000] Re: [i945gm] [karmic] X servers hangs when settings up dual monitor config
With kernel 2.6.32rc7 and xorg-edgers' intel driver (2.9.0+git), I could switch to a console (tty1), and dump kernel messages after the GPU hang (and reboot properly). It seems that by default, the Gnome screen resolution menu sets external monitor to extended at right, which could break with compiz enabled if the with is greater than 2048. But what I don't understand is why does it hang when I just run xrandr command after hotplugging the monitor? (without setting up the external monitor yet) ** Attachment added: dmesgGemErrors.log http://launchpadlibrarian.net/35683236/dmesgGemErrors.log -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 438000] Re: [i945gm] [karmic] X servers hangs when settings up dual monitor config
Ok I see, calling xrandr will by default expand the virtual screen as if the external monitor is right of LVDS, even if we directly call xrandr --output VGA1 --below LVDS. I tried with LVDS1=1280x800 and VGA1=1280x1024 (native resolutions, chosen by default). VGA1 at the right/left of LVDS1 will result in a frame buffer of 2560x1024 = greater than 2048 (i945's hardware limit), crash with compiz. VGA1 below/above LVDS1 will result in a frame buffer of 1280x1824 = Fits in 2048x2048 and works with compiz. Running xrandr --output VGA1 --below LVDS first creates a 2560x1024 frame buffer before creating the proper 1280x1824 frame buffer (seen in Xorg.0.log without compiz). Therefore, it will always crash with compiz enabled. However we can do it with metacity (compiz disabled), and then put back compiz (compiz.real --replace), it will work. In Xorg.0.log, after running the command given below: (II) intel(0): Allocate new frame buffer 2560x1024 stride 4096 (II) intel(0): Allocate new frame buffer 1280x1824 stride 2048 If you have higher native resolutions for LVDS and/or external monitor, there is currently no solution with compiz. Conclusion: The problem is that xrandr and gnome-display-properties will systematically setup the external monitor next to the LVDS, without checking if it's possible. Those tools should not do this if hardware does not allow it. The problem is that those tools are not aware that compiz is running (which reduces the hardware limit to 2048x2048), and so try to create the too large frame buffer (which is legal without compiz). -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I am having this issue with up-to-date post-release fresh install of karmic i386 32bit with intel 945gm. It is very annoying to have to restart simply to use dual head. It is very predictable and consistent. This worked just fine in Jaunty.

[Ubuntu-x-swat] [Bug 438000] Re: [i945gm] [karmic] X servers hangs when settings up dual monitor config
I've been doing some more testing on the Dell D420 referred to in #14. If I boot with the 2nd monitor connected, the system starts with the displayed mirrored. I can then use system / preferences / display to make the displays different. If I unplug the monitor, I can use system / preferences / display to reset it back to a single display and it works. If I then plug-in the monitor again, the display hangs in the same way as if the laptop was booted without a second display connected. Both primary and secondary screens are blank except for a stationary cursor on the secondary monitor. If I switch to metacity as described in this thread, dual screens just work. -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 438000] Re: [i945gm] [karmic] X servers hangs when settings up dual monitor config
The following comment in bug 383345 seems to sum up the root cause of this issue. Though, why it worked in Jaunty and not in Karmic, I don't know. No bling for me! Please, before setting dual screen, disable desktop effects (compiz). Compiz cannot work at resolution higher than 2048x2048 (yet) on i915/945 hardware, limitation of HW 2048x2048 max texture size. Without Desktop effects your dual screen configuration should work. (it is then limited to 4096x4096 framebuffer size.) With Desktop effects and resolution 1024+1024, you probably will experience this BUG. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/383345/comments/62 -- [i945gm] [karmic] X servers hangs when settings up dual monitor config https://bugs.launchpad.net/bugs/438000 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
