Bug ID: 424375
Summary: Unable to BOOT after installing kde
Product: kde
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org

Target Milestone: ---
SUMMARY
On regular Ubuntu (not kubuntu) 20.04, I installed kde with:
$ sudo apt-get install kde-standard
I got a prompt to choose a display manager, i.e. sddm, kdm3 or another one that
I can't remember.
I had no clue and the prompt screen was uninformative (that's an issue on its
own), but after a bit of research, I seemed to understand the best choice was
"sddm", so I chose that one.
After installation was complete with no error message, I rebooted.
I got nothing but a black screen for several minutes.
I turned the laptop off and on, and again, black screen forever.
My computer was BRICKED.
I was able to recover from the desaster by hitting ctrl+alt+F3, logging in via
the virtual console, and running:
sudo dpkg-reconfigure kdm3
Prompted again to choose the display manager, this time I chose kdm3.
Then I rebooted again, and this time I could get as far as the login screen.
Now, after selecting the user, I clicked on the gear icon on the bottom-right
which allows you to choose the desktop environment to log in to. I chose Plasma
(freshly installed).
After that, again a black screen.
I retried several times. No way to log in to KDE Plasma.
So I restarted again and logged in into Cinnamon.
