Unity doesn't load, no Launcher, no Dash appears
I just updated to the latest 12.04 and it recommended to restart, so I did. After the restart, only the wallpaper shows, no unity dash, no top bar.I tried to reset unity (by using tty2) but the result is the same: only the wallpaper shows. I also noticed that by right clicking, I get the desktop menu but the windows has no top bar (upper decoration with close-minimize button), if this helps.
I also sudo apt-get update
and sudo apt-get upgrade
in tty2, but there were no new packets to update.
Do you have any suggestions?
