Created attachment 1033609 [details] Xorg.0.log Description of problem: After upgraded to Fedora 22 and KDE 5, the monitor displays horizontal lines and the display is corrupted. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.99.917-10.20150526.fc22.x86_64 How reproducible: Log in to KDE and navigate for a while. Steps to Reproduce: 1. Log in to KDE from KDM 2. Use the system for a while 3. Actual results: The display is getting corrupted with the following dmesg: [53287.708030] [drm] stuck on render ring [53287.710120] [drm] GPU HANG: ecode 3:0:0x7ee6ffc1, in Xorg [769], reason: Ring hung, action: reset [53287.710125] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [53287.710128] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [53287.710130] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [53287.710133] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [53287.710136] [drm] GPU crash dump saved to /sys/class/drm/card0/error [53287.740091] drm/i915: Resetting chip after gpu hang Expected results: The display should have no issue like previous KDE 4 and Fedora 21. Additional info: The error of /sys/class/drm/card0/error and the /var/log/Xorg.0.log is attached.
I cannot add the attachment /sys/class/drm/card0/error due to error in the Bugzilla. I can mail it over. Anyway, I would appreciate a workaround. It is very irritating and it happens very often.

okay that's no good, dnf distro-sync xorg-x11-drv-intel should return you the upstream one. I've got a test kernel that might work better, https://kojipkgs.fedoraproject.org/scratch/airlied/task_9915290/ it disables a feature of the i915 kernel driver that is possibly causing the problems.
The system is already distro-sync'd. I have tested your test kernel: root@bb229:[203] ~ # uname -a Linux bb229 4.0.4-303.bz1227202.fc22.x86_64 #1 SMP Tue Jun 2 09:46:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux and it seems to work fine so far. One remark: remember to increase the version number. It is more convenient that dnf can install it as an update from a local repository and grub2-mkconfig can make it default. Currently the latest default 4.0.4-303.fc22 > 4.0.4-303.bz1227202.fc22. Is there any luck for us having integrated Intel graphics and especially for me working with an ancient model?
A workaround to stick to the testing kernel until a solution is found: # echo 'exclude=kernel-*' >> /etc/dnf/dnf.conf It will ignore all future kernel updates.
I have tested the latest kernel-4.0.5-300.fc22.x86_64 and it seems to work fine so far. Is it possible to assign it to the kernel team in order to provide more information about the resolution?
