Bug description:
This bug is about problems after resume, with Intel video hardware and
i965_dri.so. If you're having these symptoms with other hardware,
Nvidia or ATI/Radeon, this isn't the place for reports or questions.
[Those comments are building up, so brief links to direct other people
to appropriate bugs might be good here, if anyone has them. Thanks.]
----------------------------------------------------------------------------------------
This happens intermittently. Sometimes upon resume, all I see is a
black screen and the cursor. the mouse and keyboard respond (the mouse
moves) but nothing changes. Switching to console and back doesn't fix
it. Killing Compiz also does not fix the issue. Further, if one has
password lock disabled on resume the user will be stuck with a frozen
display of whatever was last shown on the screen before suspend. The
mouse cursor still changes as you hover over various elements but the
display is frozen solid. One can switch to another TTY via ctrl+alt+F1
but killing the X session is the only way to get back to the desktop.
Attempts to replace compiz have been fruitless. Trying the 3.4 kernel
also did not fix the issue.
BTW, I haven nothing connected to the laptop when I resume and before
suspend. This is a very annoying issue because the only way to
recover is to reboot, which means all the open files will be lost.
[UPDATE]
It was discovered that switching to a tty, killing compiz, then invoking
'metacity --replace' would successfully switch over to metacity. Attempting to
invoke 'compiz --replace' afterwards would put the state right back where it
was (frozen screen, etc.) and output error messages saying something similar to
"invalid configuration, this should never happen, you should probably raise a
bug report about it". After killing Compiz again and invoking compiz --replace
yet again I can get basic window management back (though unity --replace still
does not work as it whines about unclean exit states). So one still needs to
start over again to get it all functioning properly.
