 |
|
Hi Experts, I have recently installed TigerVNC server on a Gentoo machine -
| Quote: | USE="server" emerge --ask --update --newuse net-misc/tigervnc
|
Also I have installed xfce using below commands -
| Quote: | emerge --ask xfce-base/xfce4-meta xfce-extra/xfce4-notifyd
emerge --ask --deselect=y xfce-extra/xfce4-notifyd
emerge --ask x11-terms/xfce4-terminal
|
But when I am trying to bring up vncserver from one of the user accounts, I get the below message -
| Quote: | $ vncserver :11
~/.vnc is deprecated, please consult 'man vncsession' for paths to migrate to. at /usr/bin/vncserver line 43.

| I haven't tried to start a VNC server from a user account, but it works fine as a service. Edit /etc/tigervnc/vncserver.users to associate a userid to a VNC screen, then start the service; for example, with Openrc, rc-service tigervnc.1 start . Modify as needed if you use systemd. |

Hi manu.rhel,
First I'd better advise you that upstream TigerVNC have deprecated the vncserver script, and will only be supporting running the server via a service (a systemd service for that matter, but so far our Gentoo hero devs are working around that for us  ). Just to warn you, you may in future only be able to start it as a service; of course if you want to be able to start it as a user, you can simply use sudo to allow your user to start the service on-demand. (I won't bore you with the details now but just ask if you want them.)
That said, vncserver was still working last time I tried it. I'm not certain but the problem might be the lack of a config telling vncserver to start the XFCE session. For this you need a line like the following in ~/.vnc/config, or ~/.config/tigervnc/config if you want to get with the preferred current location:
Note: The value is a guess on my part, it should be named like whatever the XFCE session script is called in /usr/share/xsessions/ folder.
If you already have that, it's possible you need to add the following to /etc/tigervnc/vncserver.users (I think this is only needed for service use but I could be wrong)
After that you could check whether :1 works instead of :11 (if you still need the server to be on port 5911, I believe that's also doable). I did find it wouldn't let me use :0, which I'm sure they have their reasons for but is a bit dumb on a headless server  |

| Last time I tried, new vncserver had different symantics than old one, didn't it ? With the changes, tigervnc is useless for me, and I gave up on it. |

@dmpogo not to OT but can I ask what changes broke your setup, and in which version? |

I guess I partially overreacted (and not really needing vnc at that moment), but what frustrated me a bit is the lack of vncserver -kill :display_number functionality in the new version. I also tried to setup vncsession, and that did not fit my workflow (or I got completely confused and failed) My workflow at the time was to run several vnc sessions as a user on different displays, with different stuff. I did not use vnc for the last year or so, so never came back to it. |
