Okay so repeating my problem aggain:
I have a Dell XPS 17 (L702X) laptop with a nVIDIA GeForce 555M Graphics card inside running Ubuntugnome 13.10. Since my batterytime is amazingly small (2 hours on a 9 cell batery which gives 10-12 hours in windows) i tried to install the latest nVIDIA driver for my card in hopes of being able to use the integrated graphics instead of the dedicated card all the time (fan noices are so annoying), here comes the trouble!
After installing driver 331.20 using these commands:
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-331
I restarted my laptop and then I came to this loadingscreen where everything just stopped.
First time around I held the powerbutton and tried again and when I realised it did'nt work I reinstalled my system!
After setting all up I tried same thing again but came to same conclusion, though this time I realized I could go "Ctrl + Alt + F2" to get a terminal where I basicly ran
sudo apt-get purge "and then all installed nvidiacomponents"
and I was back to "normal"... After this I tried also instead of
sudo apt-get install nvidia-331
sudo apt-get install nvidia-current
but unfortunatly with same result.
Does anyone know if I can fix this problem somehow? It is really annoying to have my battery drained in a couple of hours when I know what it is capable of..
