Created attachment 102166 [details] dmesg from remote login openSUSE 3.16.0-rc2-5.g19015a0-vanilla Downstream bug I filed yesterday before testing with openSUSE 3.16 kernel: https://bugzilla.redhat.com/show_bug.cgi?id=1115241 Gfxchips causing display sleep that does not occur with radeon or nvidia video: i845G i865G i915G i945G (current attachment) i4000 series 32 bit and 64 bit kernels produce same behavior. Prior failing kernel: kernel-3.16.0-0.rc2.git0.1.fc21 Recent working kernel (plus all 3.15 tested): kernel-3.16.0-0.rc2.git2.1.fc21 and all of 3.15.* Latest failing kernels: kernel-3.16.0-0.rc3.git0.1.fc21 openSUSE 3.16.0-rc2-5.g19015a0-vanilla on: VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) Latest failing cmdline: ipv6.disable=1 net.ifnames=0 noresume splash=verbose vga=791 video=1024x768@60 3 I try to keep all instances of *lymout* off my installations (but sometimes they sneak in). Normally I have vga=791 video=1024x768@60 on my cmdlines, but removal at runtime has no effect on display sleep. Leaving 3 off or replacing 3 with 5 on cmdline does not help either.
It lost detected outputs. What outputs are listed in working kernels, which remain when broken? Also setting drm.debug=6 would give much more information in the log. My guess is that the VGA is lost.

int_crt_support 0 Jesse stole your VGA.
I gave it back though! From -nightly: commit 84b4e042c4707bd1bf05094a51111403d680dc39 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Wed Jun 25 08:24:29 2014 -0700 drm/i915: only apply crt_present check on VLV
I just sent a pull request to get this merged to 3.16-rc4 (or -rc5 at the latest).
