Updating Gnome removes Startup Applications under System Settings. Its only
under Tweak Tool but there is only a white border and a + symbol. Nothing
happens when pushing that button. Before updating Gnome I don't have anything
called "compton compositor" under Startup Applications.
I have been playing around with Gnome3 I think I have found a bug. At first I
thought it was a dependency problem because I was removing software included
in the Trisquel installation. When I disable "Icons on Desktop" under Tweak
Tool and then login to Gnome there is only the background. I have to open a
terminal with keyboard shortcut (Default Ctrl+Alt+T) to get rest of Gnome
back plus a terminal window.
Also when I have it disabled the right click menu is Gnome 3 style but with
it enabled its the Trisquel default right click menu.
I'm trying as informative as possible so other people can get help in the
future. But now I have hijacked this thread. I'm now giving it back.
