i've been pulling my hair off for 2 weeks now to get vnc4server to work.
after a fresh install with the lastest netinst of Debian 9 (all option to default except printing server and installed gnome) i've run as root (su command) :
apt-get install vnc4server
the installation goes well, but when i run "vncserver" it can't open any instance, i get prompt for a password, but when i enter "vncserver -list" no vnc server are running...
when i try to start it as root logs are :
Warning: nasbiantest:1 is taken because of /tmp/.X11-unix/X1
Remove this file if there is no X server nasbiantest:1
