[Nix-dev] vncserver

[Lluís Batlle]

Hello,

I want to start tightvnc x servers. I enabled xfs, as I saw the
vncserver script wants it.

The server starts fine, but no client can connect to it. I mean the X
clients, the X programs I want to start in the startup. The vnc
clients work fine, but they find no x client running in that server.

I've seen posts of people with the same problem, and most solutions
come from *not using tightvnc*, and using any other system.
The finest I've seen, which doesn't work for me, tells that the
problem appears when the server is started from an ssh session, and
that starting it after a "su $USER" works well. It doesn't work for
me, and I use a ssh session.
Nevertheless, I've noticed that if I do the "su $USER", my environment
has the XAUTHORITY variable, while in a normal ssh sesssion, it
doesn't. I don't know what puts the XAUTHORITY variable there, after
the "su $USER" command. In fact, that variable even doesn't point to
my usual ~/.Xauthority file, but to some ~/.Xauth{RANDOMCHARS}, the
randomchars being like those of mktemp().

I have this startup script:

#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

And I have this log:
