I upgraded my Ubuntu Desktop 10.10 system to 11.04 and then 11.10.
Now, when I start Ubuntu, the Unity desktop doesn't start correctly. Here's what I do:
- Start computer
- I log in via the GUI login screen
- The X Window System starts. I can see an arrow icon for the mouse, and can move it around the screen.
Nothing else starts. There are no desktop icons, no launcher, no taskbar, etc. Right clicking on desktop does nothing. I've tried some common keyboard shortcuts ("Alt-tab" "Ctrl-Alt-T" "Ctrl-Alt-Backspace") but nothing happens.
If I go to another Virtual Console, and run the command
unity, the Unity desktop will start on my primary X desktop. However I'm seeing many problems like windows which are only half-drawn, some applications run without the familiar "Minimize, Maximize, Close"
What's happening here? It seems that the X Window System started, but Unity did not start?
How can I debug this?
