I've read the other topics about this problem but my problem didn't solved. I tried to install bumblebee because of HDMI problem. I gave these commands.

sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee bumblebee-nvidia virtualgl linux-headers-generic sudo reboot

Then I got "The system is running in low-graphics" error. I tried a lots of ways but I could not solve the problem for a week. Also I can not "purge" nvidia drivers.

Here are some outputs;

dpkg -l | egrep "nvidia|bumblebee"

Try with ubuntu 14.04...I had similar problems with 12.04 but after installation of 14.04 I don't have any problems with my NVIDIA graphics cards! – Null pointer Jun 16 '14 at 12:04
Did you lose your personal documents ? If so, I can not do that – user294032 Jun 16 '14 at 12:07
Actually I took backup on external hard disk and did a fresh install! It is recommended! – Null pointer Jun 16 '14 at 16:31
Also one more advice which may work..go to /etc/X11 and rename xorg.conf file to xorg.conf.backup And reboot! This may help! – Null pointer Jun 16 '14 at 16:32

Try purging bumblebee, at low-graphics screen go to tty1 by pressing ctrl+alt+F1 and login with your user name, password and run

sudo apt-get purge bumblebee

sudo apt-get purge bumblebee-nvidia

I've tried it. Problem still exists. There are no packages like that – user294032 Jun 16 '14 at 11:58

You can try to find your driver in the text consol by taping :

sudo apt-cache search nvidia

Then locate your driver (maybe a mention to bumblebee in the name) and install it. After, you can reboot and enjoy :)

I tried it on my Ubuntu laptop and and it works well.

Good luck during your search.

This is possibly a duplicate of a question about how to completely remove the nvidia drivers (and restore unit) How can I uninstall a nvidia driver completely ?

share|improve this answer

I have solved the problem through the removing packages one by one

sudo apt-get purge nvidia-304 sudo apt-get purge nvidia-prime sudo apt-get purge nvidia-common sudo apt-get purge nvidia-current sudo apt-get purge nvidia-settings
