gnome missing!!!!

[hamidhqs]

upgrading to 12.04, I was using gnome without problem; then I used Unity shell but when I wanted to come back to gnome in login window, the gnome didn't open and instead unity opened....

Gnome shell (3) or gnome 2?

If the former, try:


sudo apt-get install --reinstall gnome-shell

If the latter, then you have problems, as gnome 2 is no longer supported. I can list several forks/clones/alternatives if that's the case.

it's gnome 3.2.1 and i did what you said but it didn't work...

Okay, just thinking of all the things that could possibly go wrong.

Things to try (note try, I have no idea what's wrong):

1) Can you run Gnome-shell/Unity3d? It's easy to get confused between Unity and Unity2d (fallback), which is what gets launched if your machine can't cope.

2) Let's go for PURGE!


sudo apt-get purge gnome-shell
sudo apt-get install gnome-shell

3) "Didn't work"? Error, or just no change?

4) Backup and (re)move any themes you've installed. It's possible they're incompatible.

Other than that, I have no clue. You may want to try a fresh install, as these often create less problems. Current GS version is 3.4...?

It's called gnome-fallback or Gnome Classic. Check Synaptic for the packages. Then select on the login screen.
