I finally managed to revert the changes in my system (from: https://forums.suse.com/showthread.php?6233-xdm-not-working-on-console-after-update)
But, now there is one problem left, and that is that no fonts are showing in Gnome.
I get a warning:
Window manager warning: Log level 16: /usr/lib64/pango/1.8.0/modules/pango-basic -fc.so: cannot open shared object file: No such file or directory Window manager warning: Log level 16: failed to choose a font, expect ugly outpu t. engine-type='PangoRenderFc', script='latin'
And both the folders /usr/lib64/pango/1.8.0/modules/ and /etc/pango are empty.
Question is: How do I restore the fonts?
