My machine is Dell Precision 5530, and I have a TB16 docking station, running Fedora 31 with Gnome. My problem is that when I lock the screen (or it auto-locks), my USB devices connected to TB16 stop working. I have to re-plug to enable them. Laptop does not go to sleep after the lock, if it matters.
After the unlock, lsusb shows that my USB devices are there, but they still do not work until the re-plug.
Any ideas on what I can try?
I have the same issue, with Fedora 32 update on my Thinkpad T480s on Thunderbolt dock … my second screen never wake up, and my system will freeze after all.
