Proposed as a Blocker and Freeze Exception for 38-final by Fedora user geraldosimiao using the blocker tracking app because: As described on this criterion "Default application functionality: For all release-blocking desktop / arch combinations, the following applications must start successfully and withstand a basic functionality test" Users expect to be able to input their passwords or choose their login as soon as the login screen shows itself with this to be chosen. Wait for more 15 to 30 seconds on a freezed screen doesnt stand for a good UX quality standard. I have two notes: * On my machines (hardware or virtualized) the "freezing" is only for about a second, but I suppose I have quite fast hardware. * The reboot options do not just show when holding the Virtual Keyboard button, but rather with any action that unfocuses the input field: for example, focusing the ">" button by tabbing once. Alright, well observed, click on keyboard layout or x11 and wayland session button too, unfocuses the input field and then shows the other options. Geraldo, can you please file a separate bug for the button problem? That doesn't seem to have anything to do with the freeze problem. They seem like different bugs. Especially since this is proposed as a blocker, they should be separated, otherwise it's unclear what we're proposing to block on.

OK, done https://bugzilla.redhat.com/show_bug.cgi?id=2180100 Probable incriminating log: sddm-greeter[7018]: Qt Quick Layouts: Polish loop detected. Aborting after two iterations. It is the last message before the "freeze" Created attachment 1952203 [details]

Messages related to sddm just before and after the freeze
Discussed at 2023-03-20 blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2023-03-20/f38-blocker-review.2023-03-20-16.00.html . We agreed to delay the decision on this issue as it's not yet really clear how many people the freeze would affect, and how long it will last (some testers report seeing no freeze, some seeing a much shorter freeze). We're hoping further investigation of the cause of this will allow us to make a better guess as to how many folks it's likely to affect, and how badly. Created attachment 1952243 [details]
new log from the moment it freezes
I compared two F38KDE vms, same config but one with sddm-x11 and this with sddm-wayland. It seems this is different at this moment of login.

another boot log from the moment
this messages are consistent
I can reproduce the delay after boot or after log out. It's about 3 sec for me, when I have my usual 3 CPU cores assigned to the VM. When I assign just 1 CPU core, the delay is about 6 sec. So this seems to be dependent on CPU speed. The amount of RAM I give it doesn't seem to affect the delay. I also see the error message from comment 8, it seems likely to be related. Can somebody please report this to https://bugs.kde.org ? Geraldo, please share your host system specs here, especially your CPU, thanks. This is my host:

(In reply to Alessandro Astone from comment #20) > Upstream: > https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2766 As suggested by Alessandro, I tested this change at both my F37KDE host, and F38KDE VM, and it worked for the freeze problem, no more waiting time at login screen (edited both breeze and breeze fedora themes) :D One sideffect of this is that now keyboard layouts at the menu button on login screen gets scrambled, no more in alphabetical order. Another PR is in: https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2767 (In reply to Kamil Páral from comment #22) > Another PR is in: > https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2767 I tested this new patch, following guidance from aleasto, and it did fix correctly the bug, without side-effects (keyboard layouts are order). Password field is responsive right from the start. User selection too, right from the start. Created attachment 1952931 [details]
screencast from the boot process with the patched sddm
With last patch bug seems fixed at F38. (tested at F37 and it works great too)
