I have installed Ubuntu 14.04 and every time I try to log in the screen will freeze and won't let me do anything else. I have tried running Ubuntu from a USB as well but the same issue still persist. The screen freezes or the whole computer locks up and I have to do.a restart. I know it has to do with nvidia graphics card but I can't seem to find the correct command to make it work. This is my first post on Ubuntu, so I apologize I know this question has been answered before somewhere.

Here is the info on video driver:

Sorry for any duplicates of the same issue if it has been addressed before. Thanks Michael

If you have installed nvidia drivers from their website, please remove it following the installer instructions. You can still login to Ubuntu using Ctrl+Alt+F1 for that.

Now follow these steps(login to terminal using Ctrl+Alt+F1) First purge any nvidia drivers

sudo apt-get purge nvidia*  
sudo reboot

Then install it from the ppa

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358
sudo reboot

For more details, refer to this thread

If sidebar is missing then try this Press Ctrl+Alt+F1 to got to tty and log in, now run this

dconf reset -f /org/compiz/

then

setsid unity

  • Thanks for the reply I did the steps above but still no go. I am able to log in but then just get a blank desktop no launcher. The desktop screen is orange and then after a few minutes the screen starts to have lines in the screen.Thanks – kb0vwg Feb 16 '16 at 01:58
  • @kb0vwg. Try the above solution. If this fixes your issue - accept this as correct answer by tick mark. – Ashu Feb 16 '16 at 02:39
  • Tried the dconf reset -f /org/compiz/ But what I get in return is. error: cannot autolaunch D-Bus without x11 $DISPLAY Usage: dconf reset [-f] path and then it gives a few arguments PATH or KEY or DIR and then returns back to the prompt for a command – kb0vwg Feb 17 '16 at 00:33
  • I am starting to wonder if this pc just does not like ubuntu period. I have ubuntu on 2 of my home computers with zero issues. they are both HP and they have nvidia video cards and no issues. I dont have much hair left to pull out lol. – kb0vwg Feb 19 '16 at 02:51
