I just had this. I cleaned up my xorg.conf file and rebooted. X was long to start and then I had displayconfig-gtk asking for configuration. I set it up and validated... nothing. I fixed the xorg.conf myself, rebooted, logged into GDM, and then apport reported a traceback similar to his.
Oddly enough, I chose precisely all the hardware I have. I had disabled the second screen (which was named "Screen 1" like the primary one). -- displayconfig-gtk crashed with IndexError in setRefreshRateIndex() https://bugs.launchpad.net/bugs/128994 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
