This is the disaster I've run into (look at the clock)
It looks like I have four X-sessions running on my screen. Everything started when I added a second monitor and plugged it to my second video card. After fidgeting with the "NVIDIA X Server Settings" I ended up with this sorry situation. Right now I have unpluged the second monitor and I am back to one monitor, one video card.
My question is: what steps do I have to take to get back to get rid of the X-sessions? I don't even know if these are extra X-sessions or what.
I tried reconfiguring the xserver
but this doesn't help. In fact, it seems I don't need and xorg.conf file in order to start an X-session!
sudo dpkg-reconfigure xserver-xorg
I'm at a loss. Any help is immensely appreciated.
