Multiple resolutions don't work after edgy install

I think this Cntrl-Alt-+/- problem applies to all edgy users.  And
someone should file a bug report and point to the patch at

It sounds like the bug is all distros using unpatched xorg 7.1.  Try
the Cntrl-Alt-+ and then try the work around xvidtune -prev or
xvidtune -next.

Mark from TWUUG gave me the clue that led me to the bug in 7.1.  I
searched for DontZoom and ubuntu...

The bug was caused by a certain someone screwing things up when they
"changed case-insensitive string comparisons to case-sensitive ones".

I am now attempting to rebuild the package, although the patch didn't
completely apply correctly - hopefully it will work...
