The problem is somehow related to the video driver. The "plug-n-play" driver which was installed by Gutsy was an "Intel experimental modesetting driver".
I changed the Driver option in the "Device" section from "intel" to "i810", and that resolved this problem, as well as several others (such as Gamma and other options in xorg.conf being ignored). While this may be acceptable as a temporary workaround, I believe the bug should be kept open, as I understand that i810 has been deprecated since Gutsy. -- Gutsy freezes when loggin out or shutting down https://bugs.launchpad.net/bugs/160342 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
