[Using XFCE 4.6.0 from Ubuntu 9.04 repo]
Suddenly XFCE started having troubles upon launch, infinite number of xfdesktop (or sometimes xfwm4) processes spawned, which cause system to lock up. I've tried delete user settings, and purge/reinstall XFCE components, but it hasn't fixed the problem. Can anyone tell me what's wrong and how to fix it?
The Session information is stored in ~/.cache/sessions/ , try deleting everything in that folder and starting Xfce again. If all else fails, see how it starts (hopefully the way it should) for a new(fresh) user.
Oh, that worked, thanks.
