A debugging feature introduced
into the X.org server 1.11 can be used by someone with physical access to the system to bypass the screensaver. First reported by "Gu1" on their blog
and on the oss-security mailing list
. The key sequence Ctrl-Alt-KeypadMultiply will bypass any screensaver. A workaround
has been posted, but one would expect an update from X.org before long.
