Thanks for your bug report. I can say that I was shocked to find that I can confirm this bug when (while trying to reproduce it) XGL died and the my X session disappeared : )
Steps to reproduce: 1. Go to System -> Preferences -> Keyboard . 2. Select the Accessibility... button at the bottom. 3. Tick "Enable keyboard accessibility features". 4. Select the "Mouse Keys" tab and tick "Enable Mouse Keys" 5. Press 8 on the numeric keypad. Expected results: Mouse pointer to move up. Actual results: XGL crashes (and bizarrely is not restarted by GDM) Version information: Ubuntu Feisty xserver-xgl 7.2.0.git.20070224-0ubuntu3 -- Xgl crashes and restarts if using Mouse Keys https://launchpad.net/bugs/31907 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
