With Plasma 4 and LightDM, I could login to my regular account as well as a Guest Account. With Plasma 5 and sddm, I can only login to my regular account. The Guest Account was great not only for Guests, but because it wiped itself with each re-boot. I marked this as a bug because it was a regression for me, but if it needs to be a wish-list, I understand.
Changed to wishlist.
Can this be considered a regression rather than a wish?
(In reply to Sergio from comment #2) > Can this be considered a regression rather than a wish? It was a regression for Kubuntu, but since Kubuntu migrated from LightDM to SDDM, I am not sure it can be called a regression for SDDM.
Yes, I agree on this. But, unfortunately kubuntu made the (IMHO very wrong) choice of forcing everyone to upgrade to Plasma 5 right now. No matter they say that they offer the choice because Ubuntu LTS is still on Plasma 4: those who updated from LTS 14.04 to 14.10 without imagining what was coming, now cannot downgrade to LTS (there is no support for this) and are forced up to 15.04 that is plasma 5 only. As of today, this is a path that is full of regressions wrt what they were used to (guest session, usable session save/restore, working screensavers, opengl compositing on older nvidia hardware with no freezes, working cpu monitor, no plasma crashes when removing widgets, hplip docking properly in the system tray, external projection screen attach with no plasma/kwin crashes, many widgets that are now missing, etc.) So the only hope of kubuntu users now is that at least the most prominent issues that they are encountering and that they did not have up to yesterday are actively treated as regression by the upstream developers since the distro, that caused the issue in first place, cannot address them.
I agree that it's a regression and should be fixed.
Upstream SDDM needs to get support before we (in KDE) can add an option for it. I'm pretty sure there's already an open issue on that there.
If this needs action both upstream /and/ in KDE, maybe it is not the best idea to close the bug, because as soon as the upstream part is done, the bug will likely need to be reopened. Furthermore, some claim that the bug can be fixed without any upstream intervention, because the sddm Xsetup and Xstop scripts are enough to support a proper guest login.
