Can't install nor load into a fresh Fedora 43 KDE on my Lenovo laptop due to Platform Trust Technology, possible video issue

try again and add also rd.driver.blacklist=nouveau modprobe.blacklist=nouveau ( if it’s a new install w/o rpmfusion’s nvidia drivers )

To update kde pls update the system first (don’t reboot) and then pull the newest kwin update from updates-testing. This is a working solution for a KDE issue on F43.

sudo dnf clean all
sudo dnf upgrade
sudo dnf upgrade kwin\* --enable-repo=updates-testing
