modesetting after hibernate
Description of problem:
Video broken when system waked up after hibernate.
System is Asus X101CH with Intel gma3600 video card.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start hibernate mode from menus or run "systemctl start systemd-hibernate.service".
2. Resume system.
Xorg video broken, see screenshot, no errors in Xorg.0.log.
I can switch to terminal with Ctrl+Alt+F2, video there is fine, then I can restart kdm.service and then video in Xorg becames fine.
Video should not be broken after hibernate.
After suspend video is fine.
Video is not broken after hibernate if fbdev Xorg driver used instead of modesetting.
I also tried modesetting 0.5.0 driver but it have the same problem with broken video.
The same problem with xf86-video-modesetting-0.6.0 driver.
This is kernel bug, it fixed in repo
But unfortunately fixes will be available only in 3.10 kernel
Broken video problem after hibernation fixed in 3.10 kernels from Rawhide.
F18 should be getting a 3.10 rebase within the next few weeks.
