Every time I start an application that is using fullscreen mode in KDE my gnome desktop background is loaded before starting the program. This is aesthetically diturbing and I suspect there is a waste of ressources when the gnome system is somehow started in the background.
Affected are:
- wine applications using fullscreen (started via playonlinux)
- virtualbox using fullscreen or scaled modus
- firefox flash plugin
What I did (inspired by some hints in various forums): replaced gdm with lightdm (flash plugin seems to be fixed now) used "killall nautilus" - but this had no effect at all.
How can I make sure KDE doesn't use any gnome programs or settings in the background without removing gnome (as gnome is used as an alternative login for testing purposes!)?
p.s.: I am using 11.04 Ubuntu with kubuntu desktop installed, 64bit, newest nvidia drivers
Here's the output of "ps aex | tee" as suggested: http://paste.ubuntu.com/678832/
Almost without a doubt I can be sure you are running Dropbox, which starts Nautilus under KDE no matter what you do. If you want nautilus to go away, you can run
killall -9 nautilus. You can even add this to KDE startup applications and have it run only in KDE.
