A ton of users are dissatisfied with the decision to change the buttons on the title bar, however, it’s incredibly easy to change back and forth between the old (Karmic) look, and the new (Lucid Alpha) look. You do not have to be on Lucid to test out the new look. These commands work fine on Karmic and (probably) older.
First, open up a terminal.
If you want your Title Bar icons to look like they do in Karmic (RIGHT side), copy and paste the following code into the Terminal and press Enter
gconftool-2 --set “/apps/metacity/general/button_layout” --type string “:minimize,maximize,close”
If you want your Title Bar icons to look like they do in Lucid Alpha (LEFT side), copy and paste the following code into the Terminal and press Enter:
gconftool-2 --set “/apps/metacity/general/button_layout” --type string “maximize,minimize,close:”
Method 2
To change the buttons layout from left side of the window to the rightside , hit the alt-F2 keys then type gconf-editor, then apps > metacity > general > button layout > menu:minimize,maximize,close
