Description James Bhatt 2010-08-25 01:38:46 UTC

I have an ATI xpress 200M.
Using the opensource radeon driver.
Using KDE4.5

I've found out how to trigger it:
Enable desktop effects, use Default settings for everything.
Apply settings.
Open any window & minimise it
Attempt to show the window by clicking on the taskbar entry.
X.org should crash.

Disable Desktop Effects, and apply settings
Open, minimise & show a window: X.org will not crash now.


I've attached xorg.0.log from when the crash happens as well: http://pastebin.com/bkgEFttr
The crash occurs at line 141

Please attach the full log file here rather than referencing a volatile external excerpt, then feel free to reopen this report.

Meanwhile, this looks related to GLX rather than EXA, reassigning.

Can you get more information about the crash with gdb (preferably with debugging symbols available for at least /usr/lib64/xorg/modules/extensions/libglx.so)?

Comment 5 Sean Robinson 2010-12-21 10:10:54 UTC

I believe I have the same error, but on 32-bit.  X server segfaults with KDE4.5 desktop effects.  Here is a GDB backtrace with symbols.  Is there any other info I can provide?

Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
