Resetting a saved gnome-session
Gnome saved-sessions may not work well with Compiz.
When i saved a session and when i tested it after logging out and in, the screen was black with only mouse pointer displayed. After 2-3 minutes the session [windows] that i saved were displayed but all windows were without title-bars, and also without borders. There was also problem with the menu and panels. The windows can be bought back to shape by disabling Compiz [from System>Preferences>Desktop Effects].
But I wanted to delete this saved session and make things as they were after installation.
The trick is to delete the session file in the ~/.gnome2. Or to be safer try renaming it to something else.
cd .gnome2
mv session oldsession
Logout and in to see the results.
