Public bug reported:
After my upgrade to ubuntu 13.04 stable I've got Problems with my dual monitor
configuration on an Intel HD 4000 Graphics System. The second monitor blanks
and gives an input frequenzy mismatch error (this one is connected using the
HDMI Output). Futher the startup Panel of unity gets purple and the whole
Session is not responsive. I'm only able to switch into a console using the
STRG+ALT+Fx command and do a reboot from there. If I switch back to X the whole
System stops responding.
I found a working Configuration using the Gnome3 in Fallback Mode w/o effects,
opening the Screen Resolution Applet, switching the second monitor off and on
again in this dialog then its working inside that session, but no way to use
Unity or Gnome with the full feature set.
It seems that the expired Bug #1155568 tells exactly the same story.
