Last stable update broke Plasma install

Desktops & Window Managers Kde Plasma
#1

After yesterday’s stable update, KDE Plasma will no longer start. SDDM starts fine, then when attempting to login, xorg seems to crash and I get dropped back into SDDM. Or other times, it will stay stuck on the splash screen, but Krunner and other keyboard shortcuts work. I am using hybrid AMD/NVIDIA graphics.

My .local/share/plasma contains look-and-feel and plasmoids , but both are empty. Therefore I doubt the problem is the eventcalendar bug that affected many users.

journalctl -b here: https://paste.centos.org/view/e12b16f6 Any help would be appreciated!

Please try to boot 20.1.1 KDE ISO to see if that fails also.

@philm I’ve had no issues booting the 20.1.1 KDE minimal iso. Additionally, removing these Plasma extensions before updating:

plasma5-applets-active-window-control-git
plasma5-applets-virtual-desktop-bar-git
kwin-scripts-tiling

had no effect.

If you installed it from AUR will not be in your home directory, but still should need another build, after the update to load properly, or removed.

#5

I don’t think I have the event calendar installed, AUR or otherwise:

% yay -Qs calendar

local/libical 3.0.8-2
    An open source reference implementation of the icalendar data type and serialization format
#6

Same Problem :frowning:

UPDATE:
in my case, it was eventcalendar issue.

#7

I experienced same issue, taskbar (I have Latte and use eventcalendar) gone or not showing up after login screen and then few seconds and black screen and only terminal and cursor…I thought this is due to Latte issue or some new updates conflicting with Latte and created standard KDE taskbar which does not contains any additional custom plasmoids extentions…but when I added also (I also use this) plasma5-applets-plasma-pstate same effect occurred as with eventcalendar

for me solution is to temporary not use both of them and wait when this issue will be solved

I had problems with Plasma too, I fixed removing .local/share/plasma/plasmoids/org.kde.plasma.eventcalendar as stated here: [Stable Update] 2020-10-01 - Kernels, Mesa, KDE-Framework, Deepin, Systemd, Pamac, Xorg-Server, Qt
