Hello KDE plasma core developer team, I hope you're having a nice day. I'm trying to build KDE Plasma desktop *from source code* on Debian, using the standard procedure based on kdesrc-build. While the building part went very well, I'm stuck on the "*installation*" part: when I log in using SDDM, I get the *loading screen then black-out with only my cursor visible* ...
I've tried everything to troubleshoot this to no avail (of course, the official page <https://userbase.kde.org/Troubleshooting/Black_Screen> didn't help), so I'm seeking help: *would you know what could cause KDE to black screen when logging in?* I will send you whatever informations/logs you may ask to help you troubleshooting; I didn't find any obvious error in my "journalctl" (I'll provide it if you request it, but because it's huge, I prefered to not include it in this first mail). Additional informations that may be important: - I'm trying to build KDE Plasma 5.27 on Debian 12 (branch group= stable-kf5-qt5). - I started from an installation without prior desktop: I do everything via TTY/SSH.$ - Install prefix is "/opt/kde/" (I did made symlinks for executables to "/usr/local/bin", and stuff). Thank you in advance, again don't hesitate to ask me if you need me to provide you with some more detailed informations. I wish you all a good continuation for your work. Regards, Matthieu 'Rubisetcie' Carteron
