Ubuntu – No graphical user interface after update on 16.04


After an update from Ubuntu GNOME 15.10 to 16.04 my gui completly crashes after GRUB. If I try a normal boot, the gui freezes there, where the LVM needs the password to decrypt the systemdrive.

I can boot into the recoverymode and decrypt the systempartition but then strange things happends.

The gui does not start and tty1 just "flashes" every few seconds. It looks like some process try to start the gui but it does not work.

If I change to tty2 or another tty the "flash" kicks me back to tty7 every few seconds.

With ps aux | grep Xorg I see, that the Xorg server is restartet whenever this "flash" happens (PID is increasing every "flash"). I can just stop it by renaming the Xorg binary.

I try to install the driver from Nvidia for my GForce 980TI


but theres an error while building the DKMS Module.
(UEFI Secure boot is deactivated).

and try the following things:

sudo apt-get purge nvidia-*
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-364

Didn't help

sudo apt-get purge xorg-* xserver-xorg; sudo apt-get install xorg xserver-xorg; sudo dpkg-reconfigure xorg

Didn't help

sudo apt-get purge ubuntu-gnome-desktop gnome-desktop-environment; sudo apt-get install ubuntu-gnome-desktop

Didn't help

It seems like I have to do a fresh install.

You might want to try to install NVIDIA drivers 361 - open a terminal and execute the following commands :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-361
sudo reboot
