(In reply to Stefan Dirsch from comment #27) > Nothing obvious in the X logfile. No idea why this results in a blank screen. well, xdm gives me a system console screen which is unusable or I don't know how to use it. reverting glibc still with xdm does not give a graphical screen but changing xcm back to sddm/glibc 2.36-4 provides graphical screen.
