Hey pramod,
what shows in your output is not a segfault, and probably not a performer
fault either.
Gdb catches a 'arithmetic exception' in a function of your video driver.
Looking at the function name, the video-driver is probably just trying the
capabilities of your system.
I've seen these before, and they are harmless in this case. You can just
'cont' after this.
If you don't want to be bothered by this signal again, you can type
'handle sigfpe nostop' in gdb. Please remember that this also turns off
stopping at other arithmetic exceptions.
Hope this helped,
Tijs Zwinkels
