#241522 — GUI browser in VNC

[Multipart message — attachments visible in raw view] — view raw

Hey,

I’d like to run a desktop in VNC and open GUI browsers like Firefox in it.

I succeeded in setting up the VNC server but after installing Firefox,
Chromium and Chrome I find they don’t open when I launch them.

Is this because I am root user?

Is it just because you should always run browsers as non-root?

Thanks very much,
Julius

Could be an environment problem. Try to open a shell, then start firefox or 
chrome from the commandline. Maybe then you might see, why it does not start.

If the other system is a linux system, you can also connect with ssh and start 
gui applications.

Note, you must use the tag -X with ssh, like

ssh -X -l myusername host_or_IP

Good luck!

Possibly. Is it too hard to try that out? Can you run any GUI app like
xterm or xclock for example?

I use the tigervnc-standalone-server package for VNC access. It allows
a VNC server to be run as a normal user. It works fine with firefox on
my system.

Set up the VNC password and the xstartup script in the $HOME/.vnc
configuration directory. The package provides tools such as vncpasswd
to help set it up, and you can set the xstartup script to start any
installed desktop environment. I have used it with gnome, lxde, and
lxqt and it works fine. I don't think the package provides encrypted
connections, though, so I only use it on a trusted private network
or with a VPN that provides security and encryption.

After installing and configuring it, start the server as an ordinary user:

$ vncserver -geometry 1024x768

You can adjust the geometry as desired and connect to it from any
VNC viewer.

I also use Xen and Xen's built-in VNC server also works fine with
firefox in my experience - Xen's built-in VNC server allows access
to Debian running in Xen unprivileged domains from any VNC
viewer, but that is probably a niche use case.

Cheers,

Chuck

Actually, looking at the man pages for tigervncserver, there are
options to provide encrypted connections using X509 certs or
TLS. This would also presumably require the VNC viewer
to support X509 or TLS security, but I have not tried it.

Also, as normal (non-root) user, you stop it with:
$ vncserver -kill :1

Chuck
