Hello.
I'm using debian 8 latest version of packages gdm3=3.14.1-7 task-xfce-desktop=3.31+deb8u1 x11vnc=0.9.13-1.2+b2 xfswitch-plugin=0.0.1-5
/usr/bin/x11vnc -norc -forever -shared -bg -rfbauth /etc/x11vnc.pass -autoport 5900 -o /var/log/x11vnc.log
After I successfully log in into any account and then trying to switch user, the image in VNC client become corrupted and if I reconnect with VNC client then only black screen appears.
The issues recovered only after
systemctl restart gdm3
(even without restarting x11vnc)
Moreover, after I finish xfce session (end session), x11vnc server crashes (although I started x11vnc with -forever option)
