** 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. - --- + 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. + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
