Re: Ubuntu Natty Kernel .debs

 

Hi Adam,

Nope I am still trying things with Jesse.

It is a regression and now filed as:
	https://bugs.freedesktop.org/show_bug.cgi?id=30877

The flickering is (if I remember it correctly) independent of the resume
stuff (flickering was already there before Jesse started adding the
resume commits).

Hehe. Then maybe wait :)

An EASY test for the flickering: Change to console (e.g. tty1) and
change back to X. If you (shortly) see a BLACK screen with white random
patterns - mostly thing lines - then you are already "infected" ;)
