About DISPLAY, remote desktop etc
I want to remotely control a computer
when I type "firefox" on shell through vpn
it prompts: "
[root@canard ~]# firefox
Error: no display specified
a solution is
while I want to use tigerVNC, a remote Desktop tool, I configure the vnc server on that computer by following the article:
my question is:
For our example I will setup vncserver to have display :3 running at a resolution of 1600×900. If you want a different number simply replace it with the number of choice.
what is the meaning of the 3 and :0.0
if I hope tigerVNC and the vpn shell are using the same window, namely, if I type "firefox" on vpn shell and I can see the opened browser window on tigerVNC client, what numbers should I set?
