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/

  • Hmmm...never heard of t9his happening before. Does it also happen when you use gdm? Could you also post the output of ps aex | tee? That will output a list of running commands. – Andrew Gunnerson Aug 19 '11 at 21:41
  • Yes it happens with gdm. The requested output is really long, how to post it here? – piedro Aug 20 '11 at 17:00
  • use paste.ubuntu.com and add a link into your question. – fossfreedom Aug 20 '11 at 17:07
  • hithere! sry for being absent for a while. Here's a link to the paste.ubuntu.com: paste.ubuntu.com/678832 . thx. But it's only about 10% of the output. semms to be cut. – piedro Aug 31 '11 at 11:55

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.

  • I stopped dropbox and the issue seems to be better now. But I have to test a bit before being sure. SO is there a way to run dropbox for KDE with Dolphin being the filebrowser? – piedro Aug 21 '11 at 11:35
  • @piedro there is (was) an application called kfilebox or something, but it doesn't work anymore, and the site seems to be down. – RolandiXor Aug 21 '11 at 21:29
  • thx roland, I use kfilebox, it's still working for me, but it loads "nautilus-dropbox" indeed! There seems to be a file browser independent dropbox daemon, but i couldn't find a deb file for it nor a comprehensive installation guide. – piedro Aug 22 '11 at 13:47
  • @piedro: yeah sucks for KDE users :(. It's one of the reasons I don't use KDE more. BTW you should mark this as answering your question. – RolandiXor Aug 22 '11 at 15:14
  • Hallo Roland! sry for me being absent for a while. It doesn't work. Even after killing everything related to dropbox, still the problem remains. I think I have to ask a more general question how to truely separate the gnome and KDE side of things on the same computer. – piedro Aug 31 '11 at 11:50
