I need some help, I installed Ubuntu 14.04 from 12.04. I had some problems when it rebooted so I had to install unity using sudo apt-get install ubuntu-desktop and continue tu update all packages using the virtual console. Ctr + Alt + F1.

But when I tried to login, after entering my user and password nothing loads, no dash, no launcher, etc. I tried everything but most I find is for older versions so I need help with this version or how to install a Gnome panel to replace unity and set it as defaul.

using ccsm show the unity plugin checked.

P.D.: I'm using an Acer Aspire 4520 with and Nvidia card.

  • If you create a new account and log in to that, do you still get the problem? – bain Aug 3 '14 at 14:15
  • I can't access anymore than login screen, even the guest account gives the same problem. I'm not very good using the console so I don't know what to do anymore. – user311751 Aug 3 '14 at 14:51
  • It is probably a Nouveau bug. Can you try booting from the 14.04.1 ISO image and see if that works? – bain Aug 3 '14 at 14:56
  • You can run sudo apt-get install nvidia-current from the text console to switch from nouveau to nvidia. Just reboot after it's done installing for the changes to take effect. – mchid Aug 3 '14 at 18:00
  • Well I tried that but didn't work and when switching forma grafic to virtual console the screen turns flashy and I cant ese anything. To resolve this I have to use an external monitor. By this moment I think that fresh installation is my solution. – user311751 Aug 9 '14 at 1:51

Had a similar problem but I don't remember what I did exactly.
I'd suggest that if you installed anything that has to do with nvidia drivers, first remove them by running sudo apt-get remove --purge nvidia-*.
Then run the following commands and afterwards reboot your system:

sudo apt-get update 
sudo apt-get upgrade
sudo apt-get install --reinstall xserver-xorg-core
sudo apt-get install --reinstall xserver-xorg
sudo apt-get install --reinstall xorg
sudo apt-get install --reinstall ubuntu-desktop

This way, you can make sure that everything works with the default drivers and only afterwards try to install nvidia stuff.


Use Ctrl + Alt + F1 to open Terminal.
Type dconf reset -f /org/compiz/ and press Enter.
Then type setsid unity and press Enter then restart your machine.
