A subsequent test result was thought-provoking. With lines in rc.conf commented out – to neither auto-load radeonkms.ko nor auto-start sddm – I got: - a command line that _was_ visible, but illegible (torn) So I _blindly_ keyed: Alt-F2 root (password) kldload radeonkms.ko Return Then I _might_ have got a successful suspend and resume, but there was a show-stopper: sddm with the manually loaded radeonkms.ko was unusable. ---- The result of: service sddm onestart – was repetitive flashing with repetition of lines, maybe the same two lines that were shown in 2015 bug <https://github.com/sddm/sddm/issues/390>: /usr/local/bin/xauth: (stdin):1: bad "remove" command line /usr/local/bin/xauth: (stdin):2: bad "add" command line Once, the repetition ended in response to a single Control-C. Then, the repetition continued until after I _held_ the Control-C combination for a while. Then, the repetition seemed endless; no matter how long I held Control-C, I could not regain a usable command line. It was necessary to (Control-Alt-Delete) restart the system. If it helps: the issue with (or affecting) xauth might have been first observed yesterday morning, Friday, a few hours _before_ I updated to r339186. Maybe after a relatively simple `pkg upgrade` routine. Housekeeping, after the experiment ================================== I removed the comments marks # from rc.conf to regain automated load and start of radeonkms.ko and sddm.
