Hello to everybody, as I'm new to this forum and relatively new to KaOS. After the major update roughly one week ago, I encountered some graphics problem on boot-up I haven't managed to fix yet. At first, I thought it's similar to the one described here: https://forum.kaosx.us/d/2533-reboot-after-upgrade-no-sddm-only-black-screen-and-mouse-pointer. However, a few seconds after the black screen, some graphical elements like the KDE Wallet Manager do show up, but I can‘t actually access them (even the clock widget on my desktop freezes immediately). The login screen generally works, but after a while, it starts to "blink" (turn on and off) but is still responsive. According to
systemctl status sddm.service, sddm is active (running). I've kept the system up to date via
sudo pacman -Syu, but nothing has changed yet. Hardware data is listed here: https://paste.ee/p/BGTJl
Booting a KaOS live system from USB on this laptop only works if I take the 2020.05 ISO, which I had used for the initial install. With the 2020.07 ISO, there‘s just a black screen and a mouse pointer, plus the error message "Configuration file /var/lib/sddm/.config/sddm-greeterrc not writable. Please contact your system administrator." However, I can boot from the same 2020.07 ISO on my other laptop: https://paste.ee/p/kZ76G. I'd appreciate any help, thanks.
