I use KDE and whenever I mount anything, such as a usb stick or cd, with a gtk program through it’s file chooser, I am unable to unmount it through the normal KDE ways. I can open a terminal and successfully umount it, but trying to do it with dolphin or the Device Notifier widget results in the following:
Could not unmount the device.
One or more files on this device are open within an application.
I know there’s nothing using any files on said volume, since issuing umount from a terminal works ok. Also, it’ll unmount ok if I mount it through a KDE/Qt app or widget. I also noticed that when mounting it through a gtk program, the folder that it gets mounted to is a random string, such as /media/XXXX-XXXX, while when done through KDE it shows up as /media/disk, or something similar.
I couldn’t find any way to deactivate this daemon or process from being started (its not started at bootup).
Anyway, there were several other gvfs processes running coming from a package named gvfs-backends, this one I deinstalled and additionally I put following line to my ~/.profile:
Now, the unmount works correctly with the plasmoid.
I couldn’t remove the gvfs package because that would mean to remove several other GNOME packages which have dependencies on gvfs.
I you find a way to prevent gvfs from beeeing started … please post :-).
I tried un-installing gvfs, which it did without any problems since I don’t have gnome installed, but then all removable media disappeared from the places box in the gtk file chooser, so I’m still trying to figure this one out.
