Dapper: Todays update, problem with XOrg

['Forum Post]

Clearly it's some sort of bug, but for now, until it's fixed, if you'll
Ctl-Alt-F2 to switch to another login screen and then Ctl-Alt-F7 to
switch back to a graphical login, you'll find that your screen is now
crystal clear (at least, that worked for me).  



This is certainly an annoyance, but I'm sure they'll have it fixed
soon, so no need to fret.
