Uninstalling these ppa packages is a real pain, by the way. -- [r200] xorg crashes in _mesa_PopAttrib() https://bugs.launchpad.net/bugs/451514 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
