Debugging is complicated. We do have a page at
https://wiki.x2go.org/doku.php/wiki:development:debugging

But most of the time there are special circumstances that lead to failure, which
cannot easily be ticked off using a checklist.

Even when it would be, the output is huge and usually needs proper
interpretation. Difficult to do so without knowing or at least looking at the code.

The general syslog, after enabling server debug output, and client debug output
(x2goclient --debug) is more important, but this issue looks a lot like
https://github.com/ArcticaProject/nx-libs/issues/679

I've only fixed the screen positioning issue today - nightly builds should
already have that fix.

A workaround is to start x2goclient on your first (normally also primary)
display. Are you starting it on a secondary (non-first) display? If yes, then
it's likely that this is causing the trouble.

You can't. User registration has been disabled due to spam bots creating
accounts and vandalizing pages. Wiki administrators (Heinz, me) can create new
accounts for users.

I typically need an email address (mandatory), a nickname (optional but
preferred, otherwise I'll guess it) and a real name (optional) for registration
and I will create an account accordingly.
