I'm on AMD64, so I can't test the i386 Ubuntu package that was posted. However, I installed xserver-xorg-video-intel_1.9.92-1_amd64.deb and xserver-xorg-core_1.2.99.902-1_amd64.deb from Debian-experimental, and it seems to have resolved several issues for me. One of the resolved issues was a system freeze that would happen while my laptop's screen was powered off.
-- xf86-video-intel 1.9.91 (2.0 RC1) is out, and would be nice to have as the source for the xserver-xorg-video-i810-modesetting package https://launchpad.net/bugs/90213 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
