Hi,

The following commit permanently turns my screen off when x server is started (i3 330M Ironlake):

[83f45fc360c8e16a330474860ebda872d1384c8c] drm: Don't grab an fb

reference for the idr

Reverting this commit fixed the issue.

This is definitely unexpected. I think we need a bit more data to figure out what's going on here: - Please boot with drm.debug=0xe added to your kernel cmdline and grab the dmesg right after boot-up for both a working or broken kernel. - Are you using any special i915 cmdline options?

Everything else should be in the debug logs I hope.

Thanks, Daniel
