Window decorations disappeared?

yesterday everything was fine and today when i logged on to my ubuntu 10.10 I noticed that the icons in the top of each menu dissapeared(I mean the the bar where the close mini maize etc..) this problem is not new for me in ubuntu 10.10 but it also happened in ubuntu 10.04 so please if somebody knows how to fix this post the answer

Solution 1:

Fixed it for now I hope it wont happened again.

I ended up running: metacity --replace in the terminal to replace the window decorations.

Solution 2:

for better GUI application, try to install Compiz fusion Icon.

sudo apt-get install fusion-icon

if your metacity is not apear again, just run the application (Applications > System tools > Compiz fusion icon), the application's tray icon will appear and then right click the icon, choose reload window manager.

make sure you have selected 'compiz' in 'Select window manager' that tray icon menu.
