Description of problem:
when executing mesa test which use e.g. openarena or tuxracer on dualhead, the game start cause that the secondary display will go off, that is ok, but quit the game will not fall the secondary display back on. I would assume that the display should be switched back on
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. have dualhead configured
2. run tuxracer or openarena
3. quit the game
4. watch the secondary monitor
secondary display stay off
secondary display should fall back to online
Don't think it is HW dependent, saw also on some Intels and nVidias.
This is... subtle. I don't think it's a regression from anything we've previously done, but I'm not sure it's desired either.
The issue, I think, is that SDL is using a Mesa GL extension for screen resizing, which Mesa implements with the XF86VidMode X extension internally. VidMode has no notion of multihead.
I suspect to fix this we'd need to teach SDL to be much smarter about pushing and popping display state with RANDR.
