UXA requires GEM, so it can only work with a kernel with GEM support. xf86-video-intel 2.9.x (the "new" driver) only supports UXA. There is no EXA or XAA support anymore. So in turn it will only run correctly on kernels with GEM support. > Also, virtual terminal > switching has been problematic over here with the new driver, so > testing it thoroughly on other systems is wise.

I don't remember if you provided more details on this to oga@ or not. But he will definatly need more information to help fixing this if possible. -- Matthieu Herrb
