Bug Description

(compiz may or may not be the right place for this - please relocate if needed)

When running unity, every now and then the display will freeze. The image remains visible on the screen, but is static - the cursor can still be moved around the screen, and ctrl+alt+F1 still brings you to a virtual terminal. When running top from tty1, it can be noted that the compiz process is still running, also no crashes appear in /var/crash/*. The only way to resolve this seems to be a reboot. The issue started occurring about 2-3 weeks ago. From memory I have encountered this lockup maybe once or twice whilst only using the internal monitor of the netbook. When an external monitor is connected however, within a few minutes the display will freeze. The machine in question is a dell mini 9 using the i915 driver.

Same bug here. The display freezes after ~30s, for around 1mn, unfreezes for 30 more seconds, freezes again.
While the display is frozen, Crtl+Alt+F1 remains active, and in fact the underlying windos are active: if I right-clik and move the cursor down where "Create New Folder" should be, a New Folder will appear when the display unfreeezes. Checking with the console shows that the forlder is immediately created. Thus, only the display is actually frozen, and the other layers are not aware of a crash at the display level.

If I let the computer idle, the display spontaneously gets dark (like when compiz crashes) and re-displayed every 2-3 mn.

Computer : Dell Studio, nvidia card, nvidia-current driver.

Here is the output of apport-bug compiz (made on tty1). Feel free to ask if more information or tests are needed.

Just a quick update to this bug: the issue persists with unity 6.6.0-0ubuntu1 and compiz 1:0.9.8.2+bzr3377-0ubuntu1. In the last few weeks I have not been able to reproduce this issue when using only the internal monitor, but it is 100% reproducible when an external monitor is connected. After the freeze has occurred, you can disconnect the external monitor, but the internal monitor changes from the frozen image to a black screen. It is possible to issue 'sudo killall Xorg' in tty1 and this brings you back to lightdm, but it kills all open windows and unsaved documents, so doesn't really help. The issue can also be reproduced using the guest session.

So just to summarize the steps to reproduce this crash:
- I have a dell mini 9 with an external monitor attached
- within a few minutes of normal usage the image on the screen will freeze (100% of the time)

(to speed up the last step you can eg open nautilus, browse to /usr/share, left mouse down on the handle of the overlay scrollbar, whilst holding the left mouse button down you can now make circle movements with your mouse which will cause nautlius to scroll up and down rapidly - this will cause the image on the screen to freeze within 10-60 seconds.)

Please copy the attached dstack script to your home directory. Then next time the hang happens:

1. Switch to a VT (Ctrl+Alt+F1) and log in.
2. Run: sudo sh dstack compiz > compizhang.txt
3. Run: sudo restart lightdm
4. Attach the resulting "compizhang.txt" to this bug.

Thanks.

This happens consistently for me in 12.10. It started happening immediately after I upgraded to 12.10. After I log in Unity is usable for a minute or so then it permenantly freezes on both screens. I am able to work around the problem by not using my external monitor but that is no practical for me because I have a netbook with a small screen.

To get out of the frozen state I start another virtual terminal, log in and sudo reboot.

My system is an ASUS eeepc.
My graphics driver is "INTEL IGD X86 MMX SE2"
I am running stock Ubuntu 12.10
I have an external samsung monitor, VGA

Additionally I noticed that there is another new bug in this version. When a window runs slow, it dims. This has been standard behaviour for several versions. Now when it dims it also has a flashing or pulsing border. I saw this both in the configuration which hangs and in the non-hanging configuration.

Hi - sorry for losing track of this bug. The freezes persist in raring with all the latest updates, so I'm reopening this bug. I've done a little research and have managed to obtain a kernel log with drm.debug=6. Perhaps this helps? If you need any other info please let me know.
