Hi, Have you ever thought about / looked at thinstation (http://www.thinstation.org/)? As far as I know, it is possible to load different configurations, settings and drivers for different machines booting on PXE (for sure, you can "filter" by IP- and MAC-address). This mechanism may possibly adapted to your system. Maybe I have misunderstood you and this info is obsolete... Kind regards Simon

Hi,

yes I tried thinstation a while ago but only the live-cd. And my experiences with hardware detection where not the best (e.g. monitor resolution). Maybe it improved in the last time. But thinstation doesn't provide a x2go-client. Does it?

cheers Stefan

Hi Neil,

thanks for answering. This is indeed a option. Since I got very good experiences with the live-helper tools from debian (http://live.debian.net/), this would be a possibility to create the live-cd-image even easier and more reproducable.

Bevor I've seen the x2gothinclient-environment I was already thinking to make a pxe-bootable live-image with x2go-fullscreen-client this way.

It's also available for ubuntu - but I've never tried. It shouldn't be more difficult than with pure debian (http://packages.ubuntu.com/de/hardy/live-helper).

But if possible I would prefer a generic debian solution.

So far I see x possibilities

1. hacking the x2gothinclientd script
2. building live-cd image (ubuntu)
3. setting up a special thinclient changeroot for each client which needs special configuration (with hard-links for all unchanged files) and booting with mac-specific pxe

Since I've got already the custom xorg.conf for the clients which behave not like they should, I'll start with 1.

For second way it would be great to use the live-helper script and to publish all configuration in the wiki. I'll do, if I find the time.

The first way quick and dirty without changing the x2gothinclientd:

I created a script /etc/init.d/x2go_xorg_custom

#!/bin/bash
# Workaround for custom xorg.conf
# tests if custom xorg.conf for mac-address exists.
# if yes copy to /ramdrive/tmp
# if no the default xorg.conf.default kopiert
# ein symbolixher Link /etc/X11/xorg.conf verweist auf diese Datei

# make shure having always the same output of ifconfig:
export LANG=C

# getting Mac-Address for the eth0 -> has to be adjusted if the interface
# isn't always eth0
xorg_file="xorg.conf.$(/sbin/ifconfig eth0|grep HWaddr | awk '{print
$5}')"

# tests if a custom xorg.conf.MACADRESS exists

if test -e /etc/X11/$xorg_file; then
  echo $xorg_file;
  else
  xorg_file="xorg.conf.default"
#  echo $xorg_file
fi

# copiing the specific xorg.conf to ramdrive
cp /etc/X11/$xorg_file /ramdrive/tmp/xorg.conf

exit 0

in the changeroot I made a link from the xorg.conf to the new one and add a starting-script before the x2gothinclientd

chroot /opt/x2gothinclient ln -s /ramdrive/tmp/xorg.conf /etc/X11/xorg.conf ln -s /etc/init.d/x2go_custom_xorg /etc/rc2.d/S19x2go_custom_xorg

Thanks a lot. Stefan

Stefan,

I tried long and hard to get the xorg.conf file to work with my monitors to no avail. Debian simply did not have the intelligence to detect various monitor configurations and I finally had to unfortunately give up.

Probably not the answer you want, however I can say that we went a different route and it's worked just fine: we decided to create a custom Ubuntu Live CD image and boot to that via PXE. Ubuntu picks up virtually any monitor settings and audio works great as well over PXE. I created a custom kiosk mode so a user boots up right to a full-screen x2go client, just as the x2go-thinclient package did. The two links I used were

https://help.ubuntu.com/community/LiveCDCustomization

and for setting up the kiosk mode, I used this description (made for NX, but just replace the NX settings with the x2go_gtk client and all worked fine). http://blog.nistu.de/A_kiosk_setup_with_nxclient.html

Let me know if you have any questions.

Neil

Hi all,

I installed recently x2go-one and the thinclient-netboot-environment. So far all works fine. (Sound and printing not yet tested).

At the same network we have also a ltsp installation but I think to

ist step by step with x2go mainly because of spee issues.

One of the main questions I have ist if it's possible to offer custom xorg.conf to the clients which boot via pxe.

Some of our monitors are not correctly recognized by the x-server an need

a

special xorg.conf.

In the ltsp changeroot there is the possibility to offer something like xorg.conf.00:00:00:00:00 with mac-address as a suffix.

I've confused this: is not in ltsp but in the pxe configuration ;-) In ltsp you define the specifics for each host in the lts.conf but maybe the client mac is still a good starting point.
