Comment 1 Paul Whalen 2013-09-05 17:42:34 UTC
Proposed Alpha blocker under this criterion:
"A system installed with a release-blocking desktop must boot to a log in screen where it is possible to log in to a working desktop using a user account created during installation or a 'first boot' utility." [1]

Comment 2 Mike FABIAN 2013-09-06 06:20:21 UTC
I see this as well, but only  when the session “Custom” is selected
in sddm. “Failsafe”, “KDE Plasma workspace (Failsafe session)”,
and “KDE Plasma workspace” work, but the selected default “Custom” 
does *not* work.

Comment 3 Jaroslav Reznik 2013-09-09 07:48:01 UTC
Based on the post on mailing list, it's not related only to ARM (and I'd say probably for Mike too). At least for now fixing the "Custom" selected as default would be a good fix for Alpha. And it's possible to workaround it by selecting the right option. Pinging mbriza to take a look.

Comment 6 Kamil Páral 2013-09-09 16:51:28 UTC
Discussed at 2013-09-09 blocker review meeting [1]. This has been accepted as an Alpha blocker. While not a 100% clear-cut violation of the criteria for KDE, this was deemed close enough to a violation to take as a release blocking bug for F20 alpha: "A system installed with a release-blocking desktop must boot to a log in screen where it is possible to log in to a working desktop using a user account created during installation or a 'first boot' utility."

sddm-0.2.0-0.5.20130821gite707e229.fc20 fixes the issue for me.

Comment 8 Martin Krizek 2013-09-10 12:04:49 UTC
Just noticed that "KDE Plasma Workspace (Failsafe Session)" is now selected as default instead of "KDE Plasma Workspace", is this expected?

Comment 9 Martin Bříza 2013-09-10 12:27:42 UTC
Martin, thanks for testing!
SDDM now lists the sessions in the same order QDir::entryList() returns them from /usr/share/xsessions . It would indeed be better if the regular session was first (and I'll address it in the future by pre-selecting it by default) but it isn't really a big problem right now.

Comment 10 Rex Dieter 2013-09-10 12:39:54 UTC
Does sddm support accountsservice and/or ~/.dmrc yet?

Comment 11 Kamil Páral 2013-09-10 12:49:42 UTC
I also thought it was fixed, then I realized I tested an already installed system. Of course the right session was picked after upgrade, it was remembered from the last attempt.

So I installed a clean TC5 DVD KDE system, booted into runlevel 3 on the first boot, upgraded sddm and rebooted. Unfortunately this is not fixed. "Custom" is still present and selected as the default.

Comment 12 Martin Bříza 2013-09-10 12:53:56 UTC
It's fixed in sddm-0.2.0-0.6.20130821gite707e229.fc20.x86_64 , not .5 (didn't notice that at Martin's comment), the update system didn't inform about the change of the update: https://admin.fedoraproject.org/updates/FEDORA-2013-16155/

Rex, not yet, AccountsService support is planned but for some reason it's listed as "Qt5 only" on https://github.com/sddm/sddm/wiki/TODO . Will ask aavci about it when he comes to IRC.

Problem fixed with .6, KDE failsafe pre-selected as default. "Custom" is gone.

Sorry, it was a typo, I tested sddm-0.2.0-0.6.20130821gite707e229.fc20.x86_64 (and I didn't log in using .5 after clean install so the choice wasn't saved from the last login in) ;)

The plan was to use this https://github.com/hawaii-desktop/qt-accountsservice-addon which is done for Qt 5 since I'm not using Qt 4 anymore but I don't think there are problems adding Qt 4 support.

I'll see if I have time on this weekend to add Qt 4 support, that will make it usable on SDDM.
