Comment 21 for bug 157213

I tried with the Hardy Alpha 2 CD today, and I can confirm that the version of xserver-xorg-video-intel (2:2.2.0-1ubuntu1) used there does NOT fix the problem. I get the exact same symptoms - flickering screen as if the refresh rate were set incredibly low - as I did in Gutsy before applying the aforementioned patch.

This bug is a potential showstopper for some Intel 855GM users, as bug #155312 prevents the use of the old i810 drivers as a fallback, essentially rendering the system unusable unless the patch is applied.
