Having successfully installed Ubuntu 11.04 I decided to look into improving look and feel of the unity desktop. I could find no option to introduce any nice effects with the standard install, but a google session suggested Compiz would do the job. I installed this and selected the "Wobbly windows" option and this worked fine.

After a while I thought I'd try some of the other available effects (can't remember which but may have been cube desktop) but this resulted in no windows showing at all. I now have just blank wall paper with no icons or menus. There are no error messages and right clicking the desktop produces a small context menu but nothing else. Rebooting brings me back to a blank desktop with just wallpaper.

I do not know where to start.

Try following commands in terminal (CTRL+ALT+T)

unity --reset
unity --replace

or instead of second command just reboot your box.

Be carefull with Compiz. Some of the features are not really working well with Unity ie. Cube plugin.

Thank for the reply. CTRL+ALT+T does nothing. No errors, just nothing but a brief flash as if a window was about to appear but then just the wallpaper again. I can change the desktop background and create documents using the right click menu so I don't think its completely broken! – Mark Sep 6 '11 at 20:04
Try to right click on a desktop and create launcher for terminal. In command field write gnome-desktop. Then launch terminal and follow the answer above. You might need to reenable wall plugin in Compiz when you restart. – Wojciech Sep 6 '11 at 20:06
Many thanks - All working again now after a reboot. – Mark Sep 6 '11 at 20:18
Command I ment was gnome-terminal not gnome-desktop, sorry for that. – Wojciech Sep 6 '11 at 20:19
No problem - now all sorted. BTW Is there a better / more stable app I should use rather than compiz? – Mark Sep 6 '11 at 20:23
