Application: kscreenlocker (2.0) KDE Platform Version: 4.4.3 (KDE 4.4.3) Qt Version: 4.6.2 Operating System: Linux 2.6.33.7-server-1mnb x86_64 Distribution: "Mandriva Linux 2010.1" -- Information about the crash: As soon as the screen saver starts, it crashes (automatically or by pressing the lock button). This problem is permanent and appeared recently. May be related to an recent kernel update and a try to install the proprietary fglrx ATI/AMD driver. Along with this new problem, the Desktop configuration in the systemsetting crashes permanently. It is now impossible to modify any setting in the desktop configuration. The crash can be reproduced every time. -- Backtrace: Application: KDE Screen Locker (kscreenlocker), signal: Segmentation fault [KCrash Handler] #5 0x00007f298da40fee in XF86DRIQueryVersion () from /usr/lib64/libGL.so.1 #6 0x00007f298da41189 in XF86DRIQueryExtension () from /usr/lib64/libGL.so.1 #7 0x00007f298da40a9c in ??

I can duplicate this bug on request as well. I also suspect fglrx, and I share all of the symptoms listed. Feel free to contact me if you need me to provide some sort of debugging information. My kernel is 2.6.32-24-generic on Ubuntu 10.04. Regards.
my kernel is 2.6.33.7-server-2mnb on Mandriva 2010.1. I tried to remove and re-install the fglrx driver with no improvement. I even tried the ati driver instead. When I click on the desktop configuration icon under the system settings tool, I can see in a split second the desktop configuration window and then it disappears. I look inside the different output logs but I could not find any useful information. I suspected OpenGL or Xrender but the 3D effects works fine and simple tool like xclock based on Xrender works as well. If I start the kscreenlocker from the console I get this message : KCrash: Application 'kscreenlocker' crashing... sock_file=/home/bdufresne/.kde4/socket-benflow/kdeinit4__0 and in the KDE crash handler : Application: KDE Screen Locker (kscreenlocker), signal: Segmentation fault [KCrash Handler] #5 0x0000000000000000 in ??

I reviewed bug 234689 and, if I'm following the thread correctly, the resolution listed there is to run "aticonfig --initial" from a command line, and/or delete your "/etc/X11/xorg.conf". I had already performed both of those procedures countless times, in every order possible. I also tried restoring various backups of xorg.conf, but to no avail. "aticonfig --initial" absolutely did not resolve anything for me. The only resolution I could find was migrating to Mandriva, which seems much more stable and reliable for me. I kind of miss Debian's packaging system, but I don't miss it *that* much. :-)
