Hi all, (sending this again in plain text; I think it did not make it through the first time because I had used html formatting)
A cursory reading of the online lit I found relating to x2gothinclient seems to require that the stations all pxeboot...
I don't want thinclients that pxeboot.. what I need is a minimal OS that is setup to autologin to X and then pyhoca-cli to the x2go-server... can the x2gothinclient packages do this say on a minimal debian install for the thinclient.. ?
Since I did not see this capability, I already built from scratch a minimal Debian 6 that does an autologin into X using gdm/matchbox wm, and then created a script that force loops a username/pw graphical dialog using yad (zenity fork)... suffice it to say this works well... but I'm thinking if x2gothinclient already had the capability to do this then I did it all for nought.. except it was definitely a good exercise...
The steps and scripts that I did do make this pxe-less x2g0 thin-client/kiosk follow ... I'm sure this can be quite improved... actually the main thing I'd like to improve is to have the matchbox wm/X on the local thin client be aware when there is no activity in the x2go session, and if no activity, then kill or suspend the pyhoca-cli session, thus going back to the yad login prompt, but I haven't found a way to do this (normal logout of the x2go session of course works fine and brings you back to the yad login prompt)... I think the problem is that matchbox wm/X always thinks there is activity when the x2go session is logged in/active, even when there is no activity in the x2go session itself...
Any thoughts on any of the above would be appreciated!
Steps/scripts etc for x2g0 thin-client/kiosk:
I sort of used the following as a guide and modified some things: http://www.alandmoore.com/blog/2011/11/05/creating-a-kiosk-with-linux-and-x1...
and went from there...
After initial Debian squeeze install with only ssh server:
Add x2go sources and install pyhoca-cli apt-get install xorg apt-get install gdm --no-install-recommends apt-get install xautolock feh wget http://archive.ualinux.com/ubuntu/main/lucid/yad_0.15.0-1~webupd8~lucid_i386... dpkg -i yad_0.15.0-1~webupd8~lucid_i386.deb (the above is an ubuntu lucid yad deb package but it worked so I didn't ask any further questions :) ... there might be a better yad package for squeeze but I could not find one) adduser kiosk (my .xprofile etc examples are for user sagotech) cp -r /home/kiosk /opt/; cd /opt/kiosk/; chmod -R a+r .; touch .xprofile chmod a+x .xprofile
To enable autologin of user into the minimal X/matchbox, add the following to /etc/gdm/gdm.conf:
[daemon] AutomaticLoginEnable=true AutomaticLogin=USERNAME
my .xprofile:
root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/.xprofile
xset s off
xset -dpms
matchbox-window-manager &
eval cat /home/sagotech/.fehbg &
xautolock -secure -time 10 -locker /usr/local/bin/suspend_pyhoca-cli.sh &
while true; do
rsync -qr --delete --exclude='.Xauthority' /opt/sagotech/ $HOME/
exec /home/sagotech/start_pyhoca.sh
done
suffice it to say xautolock does not detect non-activity in an x2go session so the suspend_pyhoca-cli.sh never ran:
root@lxtrms-thinclient-colodesk:~# cat /usr/local/bin/suspend_pyhoca-cli.sh #!/bin/bash pyhoca-cli -S
(for background behind the yad login prompt): root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/.fehbg feh --bg-scale '/usr/share/wallpaper/custom-bk-2.jpg'
The script that brings up the yad login prompt loop called from .xprofile follows... so we have this loop inside the loop of the .xprofile script... not sure if this necessary or a good thing etc.
root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/start_pyhoca.sh #!/bin/bash while true; do frmdata=$(yad --center --undecorated --image=/usr/share/wallpaper/sago-header-mod.jpg --image-on-top --button="gtk-ok:0" --title "Login to Sago Linux Terminal Server" --form --field="AD username" --field="Password:H") frmusername=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $1 }') frmpassword=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $2 }') pyhoca-cli --server X.X.X.X -u $frmusername --password $frmpassword -c startkde --sound none --kbd-layout us --kbd-type pc105/us -g fullscreen --add-to-known-hosts done
The above basically gives you a login prompt and forces you to enter a login AND password and the password is hidden when you type it it puts a nice header image at the top of the prompt.. it only gives an OK button (no cancel)... then passes off the username/pw to pyhoca-cli
So yeah I would like to improve this so that inactive x2go sessions get suspended and go back to the yad login prompt... perhaps there is a pyhoca-cli switch that does this that I'm not aware of... But even without that feature this works real nice as a non-pxe x2go thin-client station.
Anyway this is all probably very messy and amateurish, but I am not exactly a programmer or very proficient bash scripter so.. :) Also I might be missing a few steps and if any of the above does not make sense please advise and I'll try to see if I missed something in the steps given above...
Any thoughts on any of the above would be appreciated!
