Comment # 2 on bug 1176304 from Neil Rickert

I decided to test this.  And, yes, I see the SuSE logo on the lock screen. 
Note that this is the Gnome lock screen from locking the session while using
Gnome.  If I instead login to KDE, then I get a different lock screen.

When that Gnome lock screen is showing, with the SuSE logo, there are no
processes being run by user "gdm"

ps -fu gdm

does not show any running processes.  So perhaps it is a mistake to call this a
GDM lock screen.  Yes, it is similar to the GDM login screen.  But then when I
lock a KDE session, I get a lock screen similar to that of the SDDM login
screen, even though I am not using SDDM.

I won't mark this as confirmed because of that disagreement over whether it is
GDM.

Note that I did my testing with KVM virt-manager.
