I have noticed (in the past), switching from X to virtual term (Ctrl+Shift+Fx) will override/revert the ownership of /dev/drm0, resulting in above (or similar) errors when I switch back to X and run something like xlock. I say "in the past", as I have avoided above switching since. Hope this sheds some light onto the problem (or possibly as-designed behavior). --patrick > Can you include the output of ls -l /dev/drm0 and > the contents of /var/log/Xorg.0.log ? > > How are you starting X, xdm/startx/?
