my desktop files have disapeared

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

A few things that you might try:
 * Untick, then tick the option “Keep Aligned” in the context menu (right click) on your desktop – if the icons are accidentally moved out of the screen area, they should now reappear.
 * In Nautilus, move your files to another folder, then move them back to the desktop.
 * If your files are hidden, they will not show up on the desktop – type Ctrl+H while the desktop has focus.

wheal i can`t do what you told me Florin because also the right click menu does`n`t appear :) i gues there is a bug it happened when i turned the cub..

Indeed, without context menu my advice is rather worthless. I understand you are using Compiz though, seeing your reference to the cube? If that is so, you might try turning off Compiz – it might be a Compiz-related problem.

Wheal this wasn`t a suport question after all .... i just tried to point a problem that is happening to me... doing what you are telling me .... i think it`s faster to restart the system :)

thank you florin
