Backported i915 Driver

[janoble]

Whoa, it may be working. It seems logging on and off multiple times is beginning to clear up the screen. The logon prompt screen still doesn't seem to work reliably, but I'm seeing a desktop I haven't seen since last year.

I'll let you know how things eventually turn out.

Thanks for all the patience and help.

This is almost certainly worth a bug report on bugzilla.redhat.com BTW. I don't know what else to suggest than you've already tried otherwise.

Well I shut down last night and booted this morning and nothing seems to have changed from my original problem. Here's the tail end of my dmesg:

• SELinux: initialized (dev proc, type proc), uses genfs_contexts
  [drm] GPU crash dump saved to /sys/class/drm/card0/error
  [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
  [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
  [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
  [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
  i915: render error detected, EIR: 0x00000010
  [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
  i915: render error detected, EIR: 0x00000010
  fuse init (API version 7.14)

The i915 driver continues to be listed as the cause. I don't understand how yesterday it managed to work and today it's back to the Black screen and cursor.

Verified kernel: 2.6.32-504.16.2.el6.i686
Verified /etc/modprobe.d/drm_kms_helper.conf: options drm_kms_helper poll=0

I'll go ahead and submit a bug report on bugzilla.redhat.com.

Thanks for the help.
