Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen.
I have tried everything I could think about including
- Reinstalled compiz, unity, ubuntu-desktop, xorg
- Reinstalled and then removed the nvidia driver
So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all.
I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work.
Does anybody know what else I could try?
UPDATE:
sudo dpkg-reconfigure xserver-xorg
sudo service lightdm stop
sudo service lightdm start
When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there.
Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY
I can only run applications with export DISPLAY=:0
UPDATE 2:
I've reinstalled my OS and everything went fine until it updated again. After the update, unity is once again unusable.
UPDATE 3:
I ran sudo apt-get dist-upgrade and compiz was updated. Now the desktop icons are displayed but nothing more.
Also, after a reboot I got a System Error regarding Xorg. It somehow disappeared before I could see what generated the error. I tried to reboot again in order to see the error again but it didn't appear anymore.
