Output of 'dmesg'
Description of problem:
My Thinkpad X200 has been behaving badly with Rawhide kernels: system no longer detects that the laptop lid is closed and that the onlly "useful" display is on VGA1, and screen redraw is badly displaying artifacts, no background, black borders around windows, and "display memory" when windows are moved.
Since the system consders the laptop screen to be on (even when the lid is shut), my VGA display shows a solid "gray" gdm-greeter screen: the user selection/password area is not displayed. (It is actually on the LVDS if I open the lid).
Not sure what to attach to be helpful, but I'll start with dmesg output, a copy of Xorg.0.log, and a copy of gdm/:0.log.
Let me know what else I can provide that would be helpful.
Here is what I see in dmesg:

Some more detail:
I've managed to "make this work for me as expected" (i.e., Laptop LCD detected as off, graphics working, no artefacts, etc.) by including the following 2 parameters to the grub2 boot line:
'modinfo i915' says:
parm: modeset:Use kernel modesetting [KMS] (0=DRM_I915_KMS from .config, 1=on, -1=force vga console preference [default]) (int)
parm: panel_ignore_lid:Override lid status (0=autodetect, 1=autodetect disabled [default], -1=force lid closed, -2=force lid open) (int)
I'm still seeing this with latest Rawhide:
I still need 'i915.panel_ignore_lid=0 i915.modeset=1' on the boot line or the lid being closed is not properly detected, etc.
Problem persists with xorg-x11-drv-intel-2.21.15-5.fc21.x86_64 and kernel-3.12.0-0.rc6.git1.2.fc21.x86_64
Any more info I can provide that would be helpful?
I believe it is working with xorg-x11-drv-intel-2.21.15-7.fc21.x86_64:
[root@tlondon proc]# cat cmdline
BOOT_IMAGE=/vmlinuz-3.12.0-0.rc6.git4.2.fc21.x86_64 root=/dev/mapper/vg_tlondon-lv_root ro LANG=en_US.UTF-8
So, I booted without the extra i915.XX args and "it worked for me".
Hmmm... spoke too soon.
Booted again this morning; the messed up rendering returned, but the closed lid is properly sensed.
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.
More information and reason for this action is here:
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
