Hi, I'm running stretch with Xfce. Gnome is also installed. The login

Have you tried right-clicking with the mouse? My laptop with Stretch, Xfce,
and the default login manager (lightdm?) requires this.
I tried mouse buttons 1, 2 and 3. I also tried Ctl-Mouse 1/2/3,
Ctl-Alt-Mouse 1/2/3, Ctl-RightAlt-Mouse 1/2/3, Shift-Mouse 1/2/3, etc.
But no success.
