I reported this problem at https://bugs.kde.org/show_bug.cgi?id=466118 There's a report about user switching problems involving two users at https://github.com/sddm/sddm/issues/1660 Selecting Switch User resulted in a black screen 6/8 times. I had switched to VT2 in VMs and logged in as the liveuser user before selecting Switch User in the two cases when the lock screen appeared instead of a black screen. Proposed as a Blocker for 38-final by Fedora user mattf using the blocker tracking app because: Selecting Switch User in Plasma 5.27.0 in the Fedora 38 KDE Plasma live image Fedora-KDE-Live-x86_64-38-20230218.n.0.iso resulted in a black screen with sddm errors in VMs and on bare metal, and nothing appeared when I tried to switch to another VT. This problem happened unless I had previously switched to another VT and logged in as the liveuser user in which case a lock screen was shown. The Fedora 38 Final blocker criterion "User switching must work using the mechanisms offered (if any) by all release-blocking desktops in their default configuration." might be violated. https://fedoraproject.org/wiki/Fedora_38_Final_Release_Criteria#User_switching IIRC, we intend to specifically disable user switching in KDE in Fedora because it's known not to work very well. I guess what changed is that disablement got lost?

Switch User was disabled for https://bugzilla.redhat.com/show_bug.cgi?id=1929643 in kde-settings-34.5-1.fc34 https://bodhi.fedoraproject.org/updates/FEDORA-2021-a526beb5e7 The lines disabling user switching appear to have been removed by https://pagure.io/fedora-kde/kde-settings/c/c48b87a6c5447b9c9b2febe96bf94feae9ad5183?branch=rawhide in kde-settings-38.0-1.fc38 https://koji.fedoraproject.org/koji/buildinfo?buildID=2150810 Thanks. This is technically an sddm bug, though it'll be "fixed" by disabling fast user switching again in KDE Plasma. Revert applied: https://pagure.io/fedora-kde/kde-settings/c/abdb7005d5e5d8b3ccdc84ffab5bd37b0973d36c Packages building: * F39: https://koji.fedoraproject.org/koji/taskinfo?taskID=97780917 * F38: https://koji.fedoraproject.org/koji/taskinfo?taskID=97780935 +3 in https://pagure.io/fedora-qa/blocker-review/issue/1040 , marking accepted. Also proposing as a Beta FE in case the update doesn't make it before freeze kicks in. the update did get in under the freeze, so this ought to be resolved now. Matt, can you confirm the switch user option is gone in latest updates? Note this may possibly only affect freshly created user accounts. +4 Beta FE in https://pagure.io/fedora-qa/blocker-review/issue/1040 , so marking as accepted just in case this isn't actually fixed yet.

Switch User isn't shown in the Leave menu of the Application Launcher menu in Fedora-KDE-Live-x86_64-38-20230221.n.1.iso. Thanks. Awesome, let's close this then. |
