Looking at bug #73955 ... (this is on the installed Feisty now) I can't test the reproduction sequence posted by Colin Watson on 2006-12-04 because I don't have that file.
However, the reproduction command posted by wiertel on 2007-01-06, entered in a konsole session: $ /etc/init.d/console-setup restart creates exactly the same kind of screen corruption as occured just before the partitioning step of the installer. So while I'm not entirely certain, it's quite reasonable to assume that this bug is a duplicate. -- Installer / partitioning messes up X display https://launchpad.net/bugs/79269 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
