Oct 30 22:49:56 fedora systemd[1321]: Started plasma-baloorunner.service - KRunner provider for baloo file indexer. Reproducible: Always Steps to Reproduce: 1.Boot Fedora 43 KDE 2.Login screen does not appear / black screen; TTY login required 3.Enter user credentials 4.Manual startplasma-wayland Actual Results: get into kde plasma desktop and run normaly Expected Results: give me an sddm screen to login with wayland Additional Information: before updating i could not install 43, so i had to dnf remove wine-core.i686 wine-core.x86_64
I am having similar results after newly upgrading to Fedora 43; I can remediate with a tty session and running `systemctl restart sddm` to get to my login screen, and then otherwise have normal behavior. But first session attempt fails each boot after upgrading to F43 KDE on a laptop with AMD R5 5600U and integrated graphics. ayoungdukie@fedora ~> lspci -k | grep -A 2 VGA 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
