Confirm the bug here on an Acer Travelmate 6292 (Santa Rosa Platform) with Intel GMA using unity version 3.8.12-0ubuntu1.
Toggle through the Display States with the FN -Key (here FN-F5) really weird things happen. The Top-Panel is OK, then there is a black area some 50 Pixel high then the Rest of the screen is OK again. Opening an indicator menu I can only the the lower part of it, as the upper part is "below" the black area. The only way to get the normal screen back is to log out and log in again. lspci 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 03) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 03) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled upon restoring original resolution or connecting external displays -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
