[X2Go-User] How to change X2Go MaxClient setting?

["Adrián Gibanel"]

1) Maximum number of clients reached

So, I'm one of those users that have a lot windows and applications open at the same time for a long period of time.

So I reach very easily the default Xorg 256 limit and when I try to open a new Xorg program I get the following error:
Maximum number of clients reached
.

As per a quick search in a local system with Xorg this would be fixed by adding a file changing this limit to either 64, 128, 256, 512, 1024 or 2048.

Something like:

printf 'Section "ServerFlags"\n\tOption "MaxClients" "512"\nEndSection\n' \
        > /etc/X11/xorg.conf.d/99-maxclients.conf

and then restarting the Xorg server.

2) X2Go - And Xorg conf files

As I am using X2Go I know that I'm not dealing with the usual Xorg server but with an improved one based on older Xorg upstream releases.

I was expecting to find an /etc/something/xorg.conf.d/ where I could create a similar .conf but I haven't found any of this. At least, not explicitly documented.

If I'm being honest I'm not very sure if it's nxagent, nxproxy or x2agent the one process which it's an actual Xorg server.

3) How to change MaxClients for X2Go?

So my question is:

  - Can I change MaxClients with a conf file or do I have to recompile some program/library ?
  - If so Where do I create that conf file?

4) X2Go / Library versions

This is Debian 12 (Bookworm) using distro's own packages. I also have old .list file disabled. So that means that in the past I used the http://packages.x2go.org/debian repo.

I haven't found out an official way of describing/documenting your installed software towards receiving free support here so hopefully this will do it, otherwise just ask whatever you need:

5) In case it matters:
- I use x2goclient to connect to my own machine (server is localhost)
- X2Client is opened in a local Xorg KDE Plasma session with one user
- Once I'm inside X2Go I'm using a KDE Plasma with another different user

Thank you very much!
