Affects: gnome-screensaver (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Please add support for Ctrl-U in the unlock dialog of gnome-screensaver.
My muscle memory has bound Ctrl-U to "clear the line" (since that's how
{z,da,ba}sh all do it.)
