Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O
When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message – my user account and credential verification seem to be OK.
I suppose that my individual graphics configuration causes problems … I'm not sure how to reset that. I've tried stopping the UI via
sudo service lightdm stop
executed
sudo nvidia-xconfig
and restarted the UI
sudo service lightdm start
to no avail.
My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07.
Anybody have an idea how to get this fixed? Your help is appreciated 🙂

I've changed the display manager from the default LightDM to GDM by installing latter via
sudo apt-get install gdm
. With GDM set as new display manager (executesudo dpkg-reconfigure gdm
if you couldn't set GDM as display manager during installation), I could log in via the old-school graphical login screen it presented me with after a reboot.Once logged in, I reset my display manager to LightDM by executing
sudo dpkg-reconfigure lightdm
. After another reboot, things were back to normal: I can log in via the distribution's standard login UI, now.
