Greetings,

As far as I can tell this problem goes back at least 10 years, but despite reading 40-50 threads, there is no solution. david42 is a new user after doing a zypper update in prep for 42.3 upgrade. I have marked the problem in bold. root logs in without any problem. Old users, ditto. I see "solutions" like "copy an icon to .default.face" and "I don't have this problem"

I've been working with linux for a long time and this is the first time I've run into this specific problem.
