Bug Description

I'm using Ubuntu Intrepid. I recently bought a new monitor to use with my Laptop (Acer Aspire 1642WLMi with Intel graphics card), and I'm using xrandr to switch to two monitors. The commands I use are:

xrandr --fb 1280x1824 --output LVDS --mode 1280x800 --output VGA --mode 1280x1024 --below LVDS --verbose

to turn the monitor on, and

xrandr --fb 1280x800 --output LVDS --mode 1280x800 --output VGA --off --verbose

to turn it off. The problem is that when I turn the monitor off, I return to the login screen, I'm assuming because X11 restarts. This doesn't happen all the times, it usually doesn't work when I have been working on a session for some time. Some errors I found in some logs:

/var/log/gdm/:0.log.2:
(EE) intel(0): underrun on pipe B!
Xorg: intel_context.c:1020: UNLOCK_HARDWARE: Assertion `intel->batch->cliprect_mode != REFERENCES_CLIPRECTS' failed.

/var/log/syslog:

I don't know what extra files are required, please let me know if you need any extra information.

Checking a little closer, it usually happens when some specific programs are open, like Firefox or some wine programs. When these are close, X doesn't restart.

Hi jonatanschroeder,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

I'm sending both Xorg.0.log and Xorg.0.log.old, as a new log was created when X11 was restarted.

About xorg.conf, the error happens with both the original xorg.conf (using dpkg-reconfigure -phigh xserver-xorg) and this version (changed to avoid the screen to blink when I call xrandr). I'm attaching the modified version.

Hello!
I can confirm the issue - disabling the external monitor crahses X, __when Visual Effects (compiz) are enabled__.

Prerequisites:
1 you have compiz turned on
2 my monitor setup is: external monitor is on (1440x900@60Hz), laptop screen is disabled (OFF)

Steps to reproduce in Gnome 'Screen Resolution' tool:
1 switch laptop screen ON (1024x768@60Hz)
2 turn external monitor OFF
3 Apply the modifications
Result - GDM/X crashes

Work around - if you disable the visual effects before reproducing the steps, everything will go just fine.

I'll add the xorg.conf, syslog, auth.log, :o.log.1 and lspci -vvnn as an attachment

hope that helps 8)

Reassigning to xserver-xorg-video-intel on the basis of that assertion error; besides, xrandr is a client program and cannot be responsible for *server* crashes.

Um, Google search results for 'UNLOCK_HARDWARE: Assertion `intel->batch->cliprect_mode != REFERENCES_CLIPRECTS' failed.', show that it's mesa code that's doing the assertion.

FWIW I get this error on Intel 965GM:

I can confirm this on my Intrepid laptop. Unfortunately I don't have Jaunty to test with.
