You are using the open source driver. Have you tried the proprietary driver?

I havnt.

However I've had really bad experiences w proprietary drivers totally annihilating everything on my system.

Is there a safe way I can try it out and easily drop back to nouveau?

Alternatively:

Can I drop back to nouveau the drivers through the command line?

... This is really just a personal fear of mine, as I've tried the proprietary on past installs and had a week of trouble after the install failed. So I'd love to get back to using nouveau if the proprietary fails =]

Sure, just drop to root recovery mode and run:

mount -o remount,rw /
apt-get --purge remove nvidia*
reboot

And you'll use the nouveau driver again.

So I just installed the new drivers through the GUI software and it prompted me to deactivate UEFI.

I followed the directions + gave it a password.

Rebooted.

And now when I login ... the login screen comes up, I type in the (correct) password, and it simply reloads the login screen.

So should I reboot into the recovery console or what?
