I was wrong earlier about not getting an active screen under nouveau, i forgot to take the nvidia line out of xorg.conf and it was loading conflicting modules and now I can get a screen as regular user under nouveau. I tried purging and reinstalling the nvidia driver, but things remain the same unfortunately.
When i call xrandr in the console, as root, with X running, it says 'Can't open display'. If I set DISPLAY=:0.0, it just says 'Can't open display :0.0' On Sat, Sep 7, 2013 at 10:47 AM, Dave <[email protected]> wrote: > Huh?
