Ubuntu 13.10 - Black screen after logging in after installing nVidia drivers
Like the first answer removing the xorg.conf file will reset your "driver-setup".
But I've had this problem or one very similar myself. The problem lay in Optimus, a nvidia technology that allows the user to switch back and forth between integrated and nvidia graphics in order to safe power.
Now I'm assuming now that you've got optimus, if not that you can ignore this solution. You can install a program called Bumblebee that installs and manages your graphical drivers including Optimus.
to install (make sure to purge your current-nvidia settings before!!):
sudo apt-get install bumblebee bumblebee-nvidia
then reboot
sudo shutdown -r now
then after crossing your finger and a succesfull login. You can run programs using nvidia graphics using the optirun command:
optirun yourprogramnamehere
there you have it Optimus working and running.
I had the exact same problem and after searching for hours i got the solutions. Problem was, that due to installation of some software's like opencv it automatically installed nvidia drivers/graphics on NON-NVIDIA machine and due to this screen goes blank. So Just follow these simple steps to get your desktop screen back:
- Press Ctrl+Alt+F1
- Provide Login details.
- Type in terminal:
sudo apt-get remove --purge nvidia-*
sudo reboot
Done!
I am running dual 660Ti cards, with sli,and dual monitors. I had a similar problem. The main screen would boot properly, but my second screen was black. I could see in the display settings that the screen was detected, and should have been functioning. I don't know the root cause yet, as I am new to ubuntu, but I simply pressed the analog/digital select capacitive button on the front of the monitor. Now the monitor works properly. I know this is not a permanent solution, but I have seen similar results, from other users, with the brightness buttons. This may help you, until you can resolve the root cause issue.
