I made the big mistake of upgrading to Ubuntu 12.04 on my computer with NVidia card and the interface is now broken. I have to use Unity 2D and the games I used to play with my daughter are not working anymore (slow as hell). I'm trying to upgrade to the latest nvidia drivers, but I can't seem to stop the X server.
I tried to boot into console with "text" added as argument to kernel - it doesn't do anything, I still get a graphical login screen.
I tried killing Xserver with
sudo service lightdm stop
I get a
stop: Unknown instance:
If I do a lightdm restart first I can stop it, but I get a garbled console screen on which I can't read anything
I tried booting into single mode and that worked and then a telinit 3 brought me back to the graphical login screen.
What else can I do? Did I overlook something?
I tried to search in many places, but couldn't find an answer to my question (for everybody else the 'text' option seems to work)...
