Description unggnu 2009-04-03 00:38:26 UTC

I am using a i915 chip. X crashed shortly after initiating suspend which results in gdm/kdm login screen. After that chainging to text console isn't possible anymore because of a black screen. Sometimes it seems to happen on dpms activation too.

At least in my case Suspend works fine until XV is used (first XV usage results in a short flicker). I still using Overlay because the tearing problem isn't gone.

This bug was marked as a duplicates three times after checking the stacktrace. The stacktrace is from an i855 chip but it have to be similar otherwise the bug wasn't marked as one.

It has nothing to do with the xorg.conf options of the first reporter since one of the duplicate reporters have an unchanged xorg.conf and i855. It happens with the defaul Ubuntu 9.04 Kernel 2.6.28 too.

All other information are available under https://bugs.launchpad.net/bugs/345796 and the duplicates.

Seems similar to bug#21007

Comment 3 Jesse Barnes 2009-04-06 09:40:35 UTC

Yeah, looks like a dup.  Posted a patch in the other bug that should have fixed the issue.
