I have a logitech G15 old keayboard. In the past I have used g15daemon and later on gnome15.
Unfortunately both of these programs seems almost abandoned...
I removed successfully g1daemon and gnome15 but I cannot uninstall sys-kernel/lg4l-kernel-module.
If I remove the modules or do not execute 'lg4l-rebind.start', SDDM refuses to start!
No systemd errors. When I execute 'lg4l-rebind.start' sddm starts immediately.
Somewhere there is a configuration file for sddm that requires this device to be configured.
I checked udev and keyboard exists before lg4l script execution.
startx as root works fine.
Any idea how can I debug this?
