Hi Guys,
I've been a long time user of x2go and I love it, but recently I've
run into an issue where I can connect to my session from a linux
desktop, but not from a Windows desktop.
Linux Server system:
-------------------------------
- It's a VM running with 24gb of RAM and 4 CPUs, running on ESX 6.0
- xfce 4.12 is my session manager and window manager.
- CentOS 7.7.1908 (kernel 3.10.0-1062.1.2.el7.x86_64)
- I've got the following packages installed:
> rpm -qa |grep x2go
x2goserver-4.1.0.3-3.el7.x86_64
perl-X2Go-Log-4.1.0.3-3.el7.noarch
x2goserver-xsession-4.1.0.3-3.el7.noarch
x2goserver-common-4.1.0.3-3.el7.noarch
x2goagent-4.1.0.3-3.el7.x86_64
perl-X2Go-Server-4.1.0.3-3.el7.noarch
perl-X2Go-Server-DB-4.1.0.3-3.el7.x86_64
- xdpyinfo of the working server session show:

Linux desktop:
-------------------------------
Fedora 30 (kernel 5.4.21-100.fc30.x86_64) with a 1900x1200 display.
- I've got the following packages installed:
$ rpm -qa | grep x2go
x2goclient-4.1.2.2-1.fc30.x86_64
x2goserver-xsession-4.1.0.3-3.fc30.noarch
x2goagent-4.1.0.3-3.fc30.x86_64
x2goserver-common-4.1.0.3-3.fc30.noarch
x2goserver-4.1.0.3-3.fc30.x86_64
Thought I'm only using the client, not the server. This pair works
just fine, esp since they're across the country from each other with
about 80-100ms of delay, but a decently big pipe.
Windows Desktop (fails to run session)
-------------------------------------------
My failing client is a Windows 10 system, and I just recently
installed the latest x2go client to see if that would help. It's
running:
X2Go Client v. 4.1.2.2 (Qt - 4.8.6)
And it's got the same 1900x1200 display attached to the PC, but it
also fails when using just the laptop display, or another smaller
remote display at home. Annoying for sure!
When I connect from the failing client, it just closes the session
after quickly opening and showing the windows for a second, then
dying.
what's the best way to debug this, and is there any better way to
provide better debugging for end users when a connection is dropped
like this?
The session.log file doesn't seem to give any useful info when I
connect, it makes the connection, then it suspends almost
immediately. Sorry for the crappy cut'n'paste here.
