Hi,
I just stumbled over http://rpitc.blogspot.de/ - a project to turn Raspis into cheap thin clients. They're including an X2Go client in their image, too.
I'd be curious how these boxes perform under load - did anyone on this list try it out already? If no, who owns a Raspi and is willing to give it a try?

I played with a Raspberry Pi a couple of hours. It was not mine, and I do not remember which cilent version I did use, neither quality settings.
My impression is it was a bit slow to be a serious hardware to be used, even for day to day basic office/web usage.
Maybe I do test it again someday, now that I have more experience with X2go, than I did have when I played with Raspberry Pi.
hello,
yes we am testing to make x2go network with raspberry we have now in
testing phase.
as raspberry has no pxe we load raspian and x2goglient it works now we
have only 2 clients but we will do it with 5 to 10 clients
i would be very happy to have help, i am in kamerun and it is not easy
here to test
our project has the motto
computer everywhere for every body
to solve it we use solar technology low power computer (alix board as
client, now raspberry) and low power server (dual core 20 watts)
monitor 12 watts all with 12 and 5 volts imputs
assiciation linux friends limbe (cameroon)

we are an open source informatic school against digital gap between
north and south and digital gap in south between village and town

I don't know how the boot process of the RasPi works, but if it allows for booting alternative kernels/initrds, I would strongly suggest adding two bootable environments. Either as two separate partitions, or, if you're using kernel + initrd + squashfs(or nfs), two subdirectories under your boot folder. That way, you can push/pull updates of the base operating system from the running system to the non-running system in the other folder/partition and simply switch the default boot entry once the update has been completed.
I'm currently using such a code for some older non-PXE-bootable* Intel-based computers at home, but it's not ready for inclusion into X2Go yet.

*It's usually possible to PXE-boot an Intel-based computer using the images from http://boot.ipxe.org, even when the network card doesn't support PXE natively, but in my particular case, that doesn't help, either.
Hi,
From my point of view one of the advantadges of RPi is that you can easily deploy new OS images by just replacing the SD card with a different one (all v1 or v2 RPi have basically the same hardware ).
So in general I would just update one of the RPi nodes, check everything works and after that take the SD card to a standard computer and make a dd image of it. Then with that image you can update the SD cards of the rest of RPi.
If you can afford having some extra SD cards then you can just replace one SD card with the updated one.
In case you prefer network updates take into account that the network in the RPi is not especially fast because the NIC is only 100Mbits and the processor is also a limiting factor for the speed if using encrypted transfers (like scp).
Cheers, Javier

That's called sneakernet administration, and may work when all the computers are in close proximity, which may not well be the case here. It also means increased wear and tear on the SD card connector.

I believe if the poster mentioned cameroon, bridging the digital gap, and low-power, cheap devices, it is unlikely that he has much of a budget.

Why would that be a problem? You're not updating at boot, but "behind the scenes" in the other partition/directory while the main operating system is already running. if your updater uses rsync or wget, it's possible to resume where it last left off, and to throttle transfer speed. So you can set it up in a way that it takes 2 hours to transfer the image, why would a "low" transfer speed caused by 100MBit/s instead of 1GBit/s matter at all? It's done when it's done, and nothing breaks if transfer is aborted.
