Comment # 1 on bug 1080015 from Neil Rickert

I can confirm this.

This was with Tumbleweed on a KVM virtual machine.  I haven't yet applied this
update to a bare metal system.

So it booted to "gdm".  The mouse moved but could not click anything.

My temporary workaround:  I used CTRL-ALT-F1 to get to a command line, and
logged in there as root.  Then I use "update-alternatives" to switch to
"lightdm".

Everything seems fine with "lightdm", presumably because it uses Xorg and does
not use Wayland.  Login to Xorg sessions seems fine.  I have not tried login to
a Wayland session, because that never worked with "lightdm".
