I have installed Gnome 3.16 on my Ubuntu 15.04 (previously updated from 14.04) via:
sudo add-apt-repository ppa:gnome3-team/gnome3 sudo add-apt-repository ppa:gnome3-team/gnome3-staging sudo apt-get install gnome
However, I am unable to log into the Gnome desktop:
- If I select
gdmas my default desktop manager, my system boots to a black screen only showing the cursor. I can switch into tty, but no other X component loads.
- If I leave
lightdmselected, I am able to log in to Unity, but if I choose either Gnome or Gnome Classic I get a black screen for a couple of seconds after typing my password, then I'm back at the login screen. Gnome Flashback (both Compiz and Metacity options) works, but they are obviously not what I'm interested in using.
I've tried different suggestions from similar, but older, questions, including:
- Removing any
- Removing my
- Manually stopping gdm then running
None of these brought any improvement. The only potentially useful log info I can find is in the rather peculiarly-named
