When I boot I get to the login screen fine, and then after login I get a screen with my wallpaper and mouse cursor, but no menu, no dash, ctr + alt + T does nothing, clicking the mouse does nothing. I've tried to get a text prompt using ctrl + alt + F1 - F6, but they take me to a completely blank screen with no prompt, ctrl + alt + F7 takes me back to my wallpaper and cursor. All the other solutions posted need me to be in a terminal window, but I can't get into one.

I upgraded from 14.10 when this happened - the upgrade seemed to go ahead like normal. This machine originally had 10.04 on it, but has been upgraded every 6 months with no issues .... until now!

I can get into recovery mode, but don't really know what to do to fix it from there.

My machine is an ASUS laptop with a radeon HD6320 graphics and an AMD brazos E450 processor.

I have created a bootable dvd of 15.04 and that works fine!

my .xsession-errors file has some odd entries - does anyone know what they mean?

  • Did you try mount -o remount,rw / && dkms autoinstall in the root console of the recovery mode? – Karl Richter Apr 27 '15 at 20:31
  • Hi @KarlRichter thank you very much for your reply. CTRL + ALT + F1 - now works and I can log into the tty from there, and then startx brings me into a unity window. But the normal graphical login still has the same symptoms - ie just a moveable cursor and background. Any ideas? :-) – benj May 1 '15 at 13:47
  • Did you run sudo dkms autoinstall? – Karl Richter May 1 '15 at 15:54
  • Yes. Now can get a tty but no graphical interface. – benj May 1 '15 at 17:47

This is a long shot but I ran into the same issue as you and it took me an hour of trial and error to fix it. I haven't figured out why, but the unity settings are probably messed up.

You need to start the compiz config settings tool. I couldn't figure out how to start it from command line so I started up a cinnamon session where I could start the settings tool. In the settings tool I, quite frankly, messed around a bit. Checked and unchecked the OpenGL plugin and the unity plugin. I think the latter is probably what made it work, since it yelled back at me with warnings and conflicts.

After this. I logged out and logged back in again and unity was back.

  • wow this worked for me! to run compiz config settings from terminal: 1. Ctrl+Alt+T (to open up terminal) 2. then type 'ccsm' – David Lam Oct 3 '15 at 4:28

I had the same problem, and all I had to do was:

sudo apt-get install unity && unity

and my desktop immediately fixed itself.

Had the same issues here, but it didn't happen after an upgrade. I shut the laptop down in the morning and all of a sudden had no window decorations, no dash and no menu bar after booting it up tonight.

Following Leonard Broman's suggestion, I opened CompizConfig (fortunately right-clicking the blank desktop still gave me a context menu with the Open terminal option). Turns out all plugins (Composite, OpenGL, Unity Plugin, Desktop Wall, Grid, ...) where somehow disabled... I simply enabled them back and got the graphical user interface right again.
