I managed to mount my usb stick automatically via udev rules (hal isn't running). However, if I unplug the stick while thunar is open, the umount command hangs. After that I can't even reboot. But if I close thunar before unplugging the stick umount works fine. Automatic umounting is neither intended nor safe. The reason is obvious: To guarantee data consistency and proper functionality of the operating system, the file system has to be removed _before_ the underlying device is. This obviously cannot happen automatically.

Thanks for the reply. I know that unplugging the stick before umounting is kind of "unsafe". However, I never had problems with this and of course I do not unplug while files are get written. By the way the udev page on archwiki also suggests umounting in a udev rule. Finally, as I wrote before everything works if I close thunar before. And using hal it works in all cases anyway. So, I'm still grateful for further hints.

Thunar depends on HAL, so probably it is not correct to use it without HAL, and the following is from http://thunar.xfce.org "Use the correct HAL property to determine whether a given volume or device requires eject"

It can be used without hal, but not in the way that you can unplug a device without unmounting it. There's some technological difference between unplugging with and without hal. With hal: - device mounted - thunar open - device ejected without unmount - hal receives uevents and knows the device is dead - hal tells thunar that device is dead - thunar (and other hal or udisks-enabled programs) tries to close all references to the mountpoint - hal unmounts the dead device Now if you do that without hal, the point where hal detects that the device is dead and thunar getting to know that has to be done by yourself. If you forget that, you're screwed.
