Okay Im on FC6 and I just yum update, and now I have all the updates, I went to restart X but now I just get the error, "I've detected a panel already running, and will now exit" and I havn't got my taskbar or whatever its called in linux I googled it and then i ended up trying "gnome-panel" in terminal and I get the same error, I managed to create a file on desktop to launch terminal, so i can use firefox, etc...

Does anyone know what ive done // how to fix it, or what update may of done this for me to try and uninstall?

Edit, I found a fix for this EDIT: It still dont work, when I restart I have to do that again to get taskbar up.

Try the following
from terminal run
>gconf-editor (if command not found then yum -y install gconf-editor)
In the Configuration Editor
goto tab apps->panel
In the panel tab locate 1. general
2. toplevels
In the general tab the the toplevel_id_list should be [top_panel,bottom_panel]
& object_id_list should have [menu_bar,......]
In the toplevels tab there should be two tabs, bottom_panel & top_panel
Also check if autohide key is checked (in toplevels->bottom/top_panel)
If you go through the keys & values I think you may get the answer why your panel is running but not visible

Could there be an orphaned pid file that is being detected. Look before starting gnome.

Ive kindof sorted it, all those values were correct, I got it running and gnome-session-save now Ive got the panel working I don't have the bit at the top of each window with the Minimize, Maximise and Exit button it just isn't there....
