Description Andrei Kolu 2007-08-04 12:00:02 UTC 
LCD screen remains blank after Dell XPS M1210 lid is closed and reopened. Looks like LCD screen was not resumed from power-saving mode. System works without problem though- I am able to log in over ssh. Changing consoles with Alt+Fx does not give any change in screen behavior. Only solution is to type reboot- restart brings screen back.

Hardware:
CPU: Intel Core 2 T5500 @1.66GHz
Video: Intel 945GM
dmesg included.

Fix: Not known.

Patch attached with submission follows:
How-To-Repeat: Close lid and reopen it.

Andrei,

is this still an issue with recent revisions of head or stable/8?

Yes, this is still an issue with FreeBSD-8.1-STABLE-201011-amd64.

I just browsed around and thought I leave a short note...

I have had this issue since always on my Dell Latitude E7240 with Haswell i7-4600U (HD4400). Until FreeBSD 11.2-RELEASE I was using the default /boot/kernel/i915kms.ko since the kms port isn't needed for Haswell graphics.

Though, when I recently upgraded to 12.0-RELEASE I gave graphics/drm-kmod (12.0) a try and the display now always resumes correctly. It must be an issue with the old base system i915kms, as it's no longer updated if I'm not totally wrong.

Can probably be closed, because in the now-supported releases the correct i915kms.ko gets loaded.
