Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages I use a kubuntu 9.04 with kde 4.2 and nvidia proprietary drivers 180( my graphic card is a 8600MGT ). In the system-settings when I click on the display-setting, the system-settings instanannely crash with SIGSEGV 11. I think that the problem is lied to the presence of the nvidia proprietary drivers because they don't support Xrandr secifications.
This is the backtrace associated with the bug : Application : Configuration du système (systemsettings), signal SIGSEGV [Current thread is 0 (LWP 8002)] Thread 2 (Thread 0xa78a2b90 (LWP 9072)): #0 0xb7fca430 in __kernel_vsyscall () #1 0xb63ae412 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb676f344 in pthread_cond_timedwait () from /lib/tls/i686/cmov/libc.so.6 #3 0xa84bfae3 in ??
