The crash of GNOME components seems to come from Xorg bugs with the fglrx driver.
Since Ubuntu 14.4, Mesa and the free ATI video drivers are completed matured to the point that KSP can be played without FGLRX. Performance difference with my RadeonHD6850 is not noticable (KSP is a very CPU- dependend game, GPU is seldom the bottleneck), stability improvement is huge. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/1201095 Title: gnome-panel crashes after launching steam game (Thomas was alone) Status in “gnome-panel” package in Ubuntu: Confirmed Bug description: Hello, I encountered a minor problem on Ubuntu 13.04 with Gnome session in fallback mode. After running the game (even without launching steam application), both gnome panels (upper panel and the bottom one) disappear. I had started gnome-panel manually in the terminal and then launched the game. I received a following message: (gnome-panel:3447): Gdk-ERROR **: The program 'gnome-panel' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 32189 error_code 8 request_code 62 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
