There is a consistency missing between Leap-15 and SLE-15, that "SLE Classic on
Xorg" session is not available in Leap-15, only default "SLE Classic" is there
which starts to a Wayland session by default.

Discussed with xiaoguang offline. We might want some clarification what's
needed here:

1. Make Leap and SLE consistent to have both Wayland and Xorg

2. Keep Leap consistent with upstream GNOME Classic, which only has Xorg
enabled
   - SLE-15:  SLE Classic on both Wayland and Xorg
   - Leap-15: SLE Classic on Xorg

3. Keep the current status 
   - SLE-15:  SLE Classic on both Wayland and Xorg
   - Leap-15: SLE Classic on Wayland

Maybe there are better ideas that opened to discuss.
