On waking the system and switching the HDMI input, the screen showed the cursor but not the desktop. I was able to switch virtual consoles with the keyboard and confirm that X11 was running, but switching back didn't restore the desktop, just the cursor. This is under KDE. No idea what's going on. I think I'll remove the HDMI switch (I don't currently use it for anything and the other output is disconnected) and see what happens. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
