X server freezes (except for mouse) with Compiz enabled on ATI Radeon Mobility 9000
Binary package hint: xserver-
Following the lead of Nick Bauermeister and at the suggestion of Bryce Harrington here: https:/
I'm starting a bug report specific to my ATI Radeon Mobility 9000 problems.
The basics: I'm running Hardy, the latest updates as of the time of writing this (2008/03/25), on an IBM ThinkPad T40 with an ATI Radeon Mobility 9000.
Like other reports, X freezes with nothing working except for the mouse cursor. I can only break the freeze via SysRq REISUB (or waiting, more on that in a minute).
Unlike other reports, I was able to reproduce the freeze by starting Gnome Screensaver Preferences and switching to the "Braid" screensaver. What's strange is that this freeze doesn't trigger the gdb--I have to interrupt with Ctrl+C to run a backtrace. I've also discovered that this freeze will fix itself after some time (anywhere from 5 minutes to an hour in my testing). I managed to get a gdb run that consists of two SIGPIPE broken pipes during login, a SIGPIPE running the actual Braid screensaver, and multiple SIGINT Ctrl+C interrupts during the suspicious freeze with mouse still working. I ran backtrace full each time gdb stopped, either on its own or from my interrupt. The last four or five backtraces are probably the ones of interest, all stemming from the Braid screensaver, subsequent freeze, and (after a long wait) recovery.
Note: Unlike Nick Bauermeister's bug report at https:/
Hope this helps.
