Damn, apparently the nvidia driver is not actualy in use, even thoug
additional drivers tab under software and sources claims it to be in
use. "sudo lshw -c video" gives the following output:
*-display

In other words, the nouvea driver is still in use. Any ideas on how I
can get nvidia driver working properly, so that I can test it with
upstream kernel?
I have switched between nouvea and proprietary driver many times in
software and sources and rebooted, but this doesn't seem to work...
