I upgraded from Ubuntu LTS 14.04 to LTS 16.04. I have a problem and it's that my computer doesn't charge any environment desktop (I've installed MATE, LXQt and KDE Plasma 5.7). It just shows "Ubuntu 16.04 LTS ubuntu tty1" and the option to log in. Any ideas?

Thanks beforehand.

Graphics Drivers

I would say that your drivers for your graphics card were not properly installed. To fix this just login to the command line (without desktop environment) and do this:

If nvidia, choose a drivers from this list and install it with apt:

First you must uninstall the old drivers that are not working:

sudo apt-get --purge remove xserver-xorg-video-nouveau

Otherwise use the open source Nouveau drivers that ubuntu provides, try reinstalling them:

sudo apt-get install xserver-xorg-video-nouveau

You can find out which one to install by going to the nvidia drivers website and putting in your system and card information

If you have a radeon/AMD card then I would follow this

NOTE: Because you haven't posted any logs of your system I can't do any debugging and this answer may not work.

Other possible problems

• It could be as simple as switching to another terminal using alt-<f7>

• Grub might need to be reinstalled on your system: grub-install /dev/sda

• Try restarting the xserver systemctl restart lightdm

  If none of this works your going to have to post the logs somehow or just post the error message.
