I'm experiencing the weirdest problem right now. Nautilus is essentially not working right now. My desktop is frozen, clicking and right clicking doesn't work, I can't open anything in nautilus, etc. It simply is broken. The problem is that I can't exactly kill it with anything.

while true; sudo killall -9 nautilus ; done doesn't kill it.

I can't log out because I'm right in the middle of a long upload and I'm not going to kill it if I can help it. Is there something I can do to reload nautilus without logging out?

FYI, I was having the same issue. In my case, it appears to be caused by a faulty mount point somewhere in my FS tree.

Specifically, the culprit was a samba mount (cifs) that failed due to me losing VPN. As nautilus mentions these under 'Network' in the left sidebar, I'm guessing this caused it to hang. As a work-around I remounted all my volumes (sudo mount -a) and now nautilus is responsive again.

this was my case; I had a couple of autofs directories in the left sidebar and they were not accessible. This caused nautilus to always timeout, no matter what. I'm not sure why deleting all nautilus configuration didn't solve this though, disabling autofs mounts did. – Riccardo Cossu Jun 13 at 10:01

Have you tried nautilus -q already?

It exits (and restarts) nautilus. I use it when it hangs or when i need to "refresh" it after installing new nautilus context actions

Command hangs and nothing happens. Whatever's messed up here, it is seriously messed up. – Naftuli Tzvi Kay Aug 31 '11 at 18:04
Still same here in Ubuntu 12.04. Nautilus hangs quite often and kill/killall does not show any effect. 'nautilus -q' just states "Could not register the application: Timeout was reached". – Seven Apr 10 '13 at 12:44
12.10 and I get the same message "Could not register the application: Timeout was reached." – jwigley May 26 '13 at 23:44
Same here, with Ubuntu 14. – Bzazz Dec 4 '14 at 15:50

Running the command

killall nautilus

fixed this for me - it may help a future visitor.
