in debian jessy you can see the desktop but some areas are very dark.
I cannot see terminal, cannot type, mouse pointer also very dark. I lost it time to time.
I removed xfce and installed lxde in debian (with physical serial terminal) with below commands:
sudo apt-get purge xfconf xfce4-utils xfwm4 xfce4-session thunar xfdesktop4 exo-utils xfce4-panel xfce4-terminalsudo apt-get autoremovesudo apt-get install task-lxde-desktop
but there are still problems, lxde menus cannot be closed, the desktop is not refreshed, you open and close windows, but there still remaining buttons etc. very interesting..
What commands are you using to remove xfce completely?
I will try ubuntu again with lxde.. I am building images from 150balbes github repository.
