Simply removing the USB flash drive is what is supposed to be done. If the folder remains, then something goes wrong on the server-side (in x2goumount-session), maybe in X2Go Client (dunno otoh).
Well, that's not what's happening. I was able to confirm the behavior on my test system.
On the ThinClient,
/media/Manufacturername/rawdevice # like sdb
and
/media/Manufacturername/partition # like sdb1
remain after unplugging the flash drive.
I just checked, x2gousbmount contains a step to force-umount the media after removal, and to somehow let X2GoClient know about it by doing things in ~/export/, but it never contained a step to remove the directory *on the thinclient*.
Also, it looks like the X2GoServer is simply monitoring directory existence on the thinclient - because as soon as you manually rmdir the empty directory on the thinclient, it also disappears from the server.
I could simply add an rmdir step to the umount routine in x2gousbmount, but given what you wrote above, I'm wondering if it's supposed to happen somewhere else, and failing.
Any insights? Should I proceed or go rmdir-grephunting across the X2Go source first?
Digging further into this, it looks like that on the server, x2goumount-session is responsible for deleting the stale desktop shortcuts.
HOWEVER ...
a) It exists twice, once as x2goumounts-session, once as x2goumounts_session. Not symlinked, but two separate files. WTF?
b) it contains a *hardcoded* path that makes it check /media/disk only, with a big fat FIXME note on top that this needs to be changed to handle CD-ROM and removable media mounts as well. So it's kinda obvious why it's not working for removable media ...
c) It looks like neither x2goumounts-session nor x2goumounts_session are being called upon stick removal (there's no "x2goumount-session has been called [...]" message in the syslog at all).
Harumph.
