** Description changed:
Ever since I installed Ubuntu 12.04 x86-64, I've experienced several X
crashes/freezes each day. Sometimes it happens when I play a Flash
video on the web, or when I play a local video file. Sometimes it
happens when I have multiple Firefox windows open, and I click on the
dock icon to reveal both windows.
Sadly, although the bug triggers frequently, I've had difficulty
reproducing it consistently. I'll play a video and X will crash, yet
after restarting X or rebooting the machine, the same video plays fine.
When the bug occurs, the screen freezes with the exception of the mouse
cursor. I can SSH into the machine. Killing the X process *usually*
works just fine: the desktop environment starts right back up and I can
continue using the machine until the next freeze. However, the last
time I tried this the desktop environment never restarted, and I
rebooted the machine.
My current uptime is 18 hours, but most of that time the machine was
sitting there idle. If history is any indication, I can expect a crash
by the end of the day.
Anecdotally, the freeze seems more likely when I have several
applications open (Firefox with several tabs, some of which may contain
Flash video; the Terminal; my Downloads directory in a file manager
window; and perhaps VLC). Freezes seem more likely when using Compiz
effects like when I switch applications.
Please excuse me for not using Ubuntu-specific terminology. I use
several different OSes on any given day and it's hard for me to keep
track of the names of every application, subsystem, etc.
I don't normally maintain distribution code, so please let me know what else
I can do to help fix this bug.
