Public bug reported: I'm using ubuntu 14.04 LTS, as well as tried to load 15.04 dev build downloaded today. Display showing black and white rectangles with some color noise. When in switch to text i see errors from nouveau driver telling "PGRAPH TLB flush idle timeout fail". And i see it is happening in infinite loop.
the only way to me to boot into X is to use "nomodeset". I dont want install nvidia proprietary drivers, since i will need to use Xen later and it won't work with them.
