Appeared that no /etc/X11/xorg.conf file caused this behavior.

Created one (as root in terminal) with X :1 -configure ; ignored the error messages and copied the resulting xorg.conf.new as xorg.conf to /etc/X11/

Login screen after (re)boot is fine now

edit: I noticed that llvmpipe as driver is used now, makes the compu very slow When radeon driver is loaded, problem still exists. Card is a ATI Radeon X1270

Can't understand why initial boot login screen is flickering and the returning login screen after logout isn't. The latter only begins to flicker when i close the lid (suspend?) and open it again.

have to live with it, i guess...

switching to lightdm ( # yum install lightdm lightdm-gtk; systemctl disable gdm.service; systemctl enable lightdm.service ) did the trick. Beautiful clear after-boot-login-screen. After login to Gnome, no screen issues.
