I also have (had?) this issue. I highly suspect that at least in my case the problem is that I installed amd's catalyst driver for my radeon card. Since catalyst doesn't support my card the xorg radeon driver is used.
I got the exact same stacktrace whenrunning glxinfo. I then uninstalled catalyst and can now run glxinfo. I don't know how to reproduce the error with gnomescreensaver so I can't verify that it is the same issue. -- gnome-screensaver-gl-helper crashed with SIGSEGV in XF86DRIQueryVersion() https://bugs.launchpad.net/bugs/529418 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
