Hi, I need a GUI application (RetroShare) to start on boot on my headless server (Debian Wheezy up to date with x2go repos) and be available remotely. I got it working with the scripts below but it's cumbersome. Is it how it is supposed to be done ?
I only encounter two issues apart from the complexity : -- x2goclient (v4.0.1.0 on my PC) resolution is ignored and Xvfb startup resolution (900x550) is used even after it has been killed. -- Caps Lock cannot be used, because once it has been, it stays on.
Regards, Yohan
scripts :

There should be no need for using Xvfb. X2Go has its own X-Server
(x2goagent/nxagent), so when using Xvfb, you actually use X-Servers.
Why not go this approach...
pyhoca-cli --server localhost -N -c LXDE --user yohan
--add-to-known-hosts --password mypasswd
--kbd-layout fr --kbd-type pc105/fr &
sleep 5 X2GO_SESSION=$(<detect-session-id-of-just-started-session>) <launch whatever application you want to launch in session $X2GO_SESSION>
# Whenever you need that application on screen... pyhoca-cli --resume $X2GO_SESSION --server localhost
This can also be done rootless, just by not using a desktop shell
command as --command:
pyhoca-cli --server localhost -N -c <YOUR-COMMAND-IN-$PATH> --user yohan
--add-to-known-hosts --password mypasswd
--kbd-layout fr --kbd-type pc105/fr &

Hi Mike,
There should be no need for using Xvfb. X2Go has its own X-Server (x2goagent/nxagent), so when using Xvfb, you actually use X-Servers.
Why not go this approach...
pyhoca-cli --server localhost -N -c LXDE --user yohan
--add-to-known-hosts --password mypasswd
--kbd-layout fr --kbd-type pc105/fr &sleep 5 X2GO_SESSION=$(<detect-session-id-of-just-started-session>) <launch whatever application you want to launch in session $X2GO_SESSION>
# Whenever you need that application on screen... pyhoca-cli --resume $X2GO_SESSION --server localhost
I just tried but it failed for some reason... LXDE was never started and the session terminated. I also tried as root just to be sure : # pyhoca-cli --server localhost -N -c LXDE --user yohan --add-to-known-hosts --password mypasswd --kbd-layout fr --kbd-type pc105/fr & [1] 5440 # xwininfo: error: unable to open display "" pyhoca-cli[5440] NOTICE: preparing requested X2Go session pyhoca-cli[5440] (PyHocaCLI) NOTICE: preparing requested X2Go session pyhoca-cli[5440] (x2gosessregistry-pylib) NOTICE: registering X2Go session Pyhoca-Client_Session... pyhoca-cli[5440] (x2goclient-pylib) NOTICE: initializing X2Go session... pyhoca-cli[5440] (x2gocontrolsession-pylib) NOTICE: connecting to [localhost]:22 pyhoca-cli[5440] (x2goproxy-pylib) ERROR: Bringing up NX3 proxy failed. pyhoca-cli[5440] (x2goproxy-pylib) WARN: X2Go proxy shutdown gave a message that we may ignore: [Errno 3] No such process pyhoca-cli[5440] (x2goclient-pylib) WARN: HOOK_session_startup_failed: session startup for session profile ,,Pyhoca-Client_Session failed. pyhoca-cli[5440] (PyHocaCLI) NOTICE: give the X2Go session some time to come up...

This can also be done rootless, just by not using a desktop shell command as --command:
pyhoca-cli --server localhost -N -c <YOUR-COMMAND-IN-$PATH> --user yohan
--add-to-known-hosts --password mypasswd
--kbd-layout fr --kbd-type pc105/fr & I tried this without any luck either :
[1]+ Fini pyhoca-cli --server localhost -N -c LXDE --user yohan --add-to-known-hosts --password mypasswd --kbd-layout fr --kbd-type pc105/fr pyhoca-cli --server localhost -N -c /usr/bin/xlogo --user yohan --add-to-known-hosts --password mypasswd --kbd-layout fr --kbd-type pc105/fr
It seems pyhoca-cli requires an active xserver to start. No ? Both commands work if I launch them from my PC, but as I said I am trying to start the application on my headless server when it boots with /etc/rc.local. Hence the ugly hack I did with Xvfb. If there is no way to do that (other than using Xvfb), I'll probably start the application from my PC with the command you suggested. My server does not reboot that often anyway.
Thanks for helping me out. Regards, Yohan
