It sounds like nautilus is blocked waiting for one or more slow mounts. Most likely that's a network mount, so try removing any of those temporarily. Less likely it's a local disk failure.
Please also check that the problem is not high CPU by running 'top'. If you can't find the source of the problem then please: 1. Reboot to create a fresh system log. 2. Reproduce the problem once. 3. Immediately run: journalctl -b0 > journal.txt and attach the resulting text file here. ** Package changed: gnome-shell (Ubuntu) => nautilus (Ubuntu) ** Changed in: nautilus (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1899720 Title: Gnome takes MORE THAN 20 SECONDS to open a folder To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1899720/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
