Comment 57 for bug 749817

Affects me on Thinkpad T410 w/ Intel integrated graphics. External screen connected via display port. Screen set to span both displays. When I start the computer, external display is blank. Then I need to shut down, start up again for external screen to show.

Both screens show different resolutions (external screen is higher resolution than laptop screen). Sometimes, when I go into monitor settings, and change the resolution, and apply the settings, the desktop does not re-render correctly (parts of the screen are missing or corrupted and I need to reboot).
