Thank you for the excellent advice. I switched the virtual machine acting as my tftp server to Debian 11 and pxe boot started. I didn't event need to chainload ipxe with undionly.kpxe. Basically using Ubuntu for my tftp server was the problem. Something of note, though. It was necessary create a new directory /srv/tftp/pxelinux.cfg and copy /srv/tftp/default.cfg into it. I discovered this by consulting professor Google. I did not read this in the classic X2go-tce documentation. Perhaps this might be explictly added to this documention to help nubes like myself? I am having more problems, though. The first, red X2go splash screen comes up but I am unable to make any selections, not with the highlighted hotkeys nor with the arrow keys or even TAB. Not a real problem, after timeout it defaults to x2go-tce which is what I want anyway. I just mention it in case it is a symptom of the other problems I'm about to describe. The boot soon fails with the following messages: [ 16.996870] Initramfs unpacking failed : write error[ 17.488013] mce: Unable to init MCE device (rc: -5)[ 19.959922] Failed to execute /init (error -2)[ 19.190964] Kernel panic - not syncing: No working init found.

Try passing init =option to Kernel. See Linux Documentation/admin-guide/initrst for guidance. ]--- Then the whole thing hangs up indefinitely. It seems to me that the old thin client (TK-3550 AMD GX III LX800 CPU, 256 MB ram) needs a legacy BIOS boot and this is unavailable for some reason. Should I redo my X2go-tce setup (x2gothinclient_settings) and use an older version of Debian to create the chroot image? I used the default "Buster". If I need to go back enough versions of Debian will I need to change to archived repositories in the same file (rather than just http://ftp.debian.ors/debian <distr-codename> main)? Do I need to add to the APPEND line of x2go-tce.cfg instead with init=/sbin/.... or some such (professor Google again)? Once again any help here would be appreciated. I recognise that the thin client I am using is rubbish but the price was right and having come so far I'm reluctant to give up now.

At one time, when, about a year ago, while installing x2go on ubuntu, I faced about the same problem. Nevertheless, in a week I was able to run x2go-server + pxe. Endless poking around in the configuration files gave me the idea to change the distribution kit. Imagine my surprise when, in 30-40 minutes, I installed and configured this bundle on Debian_10 without any problems and have already been using it with 20 clients for a whole year. I also did not find understanding and help in the x2go community. My advice to you is to change your distribution to Debian.

Hello,
I posted an enquiry quite some time ago but it hasn't attracted anyone's interest. In the meantime I have contiued trying to solve the problem on my own. I moved all my dchp functions from my cheap, rubbish router to my ubuntu 20.04 server. I spent some time fiddling with the settings of isc-dhcp-server. I downloaded ipxe undionly.kpxe and put it in my tftp server (a virual box virtual machine with bridged netwrking also running a ubuntu 20.04 server) at /srv/tftp. When I boot up my Termtek TK3550 Thin Client (AMD GX III LX800 CPU, 256 MB ram, Intel UNDI network card PXE 2.0) undionly.kpxe is successfully booted via tftp and the new bootloder finds pxelinux.0 then just locks up. Nothing happens and it continues to happen indefinitely. I have attached a photo of the boot screen when it locks up.
I have created a directory of the tftp server /srv/tftp/pxelinux.cfg . I copied /srv/tftp/default.cfg into this directory both as default.cfg and as simply default. I also copied x2go-tce-cfg, memtest.cfg and local-boot.cfg into this directory just in case. I am now at a loss. I have no way of checking/altering pxelinux.0 as it is in binary or code of some sort. I have spent hours in my free time to get this far, but in reality the end goal of logging into my linux server on a thin client seems no closer. Any help would be appreciated.
