Re: [X2Go-User] Can't get X2Go connection opened, with error PANIC! The remote NX proxy closed the connection.
Thanks. So nx is working. To be honest I am out of ideas now. Have you checked what updates were installed on the server recently? Can you downgrade and retry?

Hi Ulrich NX Agent appeared and Xterm opened inside it. BR, Kalle On Fri, 10 Mar 2023 at 13:20, Ulrich Sibiller wrote: > Hi, > > again I don't see any major problem in libssh related output.

Re: [X2Go-User] Can't get X2Go connection opened, with error PANIC! The remote NX proxy closed the connection.
Hi, again I don't see any major problem in libssh related output. But I see these: qt.qpa.xcb: X server does not support XInput 2 qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, resource id: 309, major code: 130 (Unknown), minor code: 47 NX does not support XInput 2. So these errors indicate the session has been opened successfully but some application had a communication problem with the X server (x2goagent in this case). So chances are that xterm, libxcb, libX11 or any accompanying library have been updated recently and are incompatible now. Maybe we can hunt this down by checking this: 1. ssh -X and run "nxagent -D -ac :55" there (nxagent window should open up) 2. ssh server and run "DISPLAY=:55 xterm" there (xterm should open in the nxagent window) Does the xterm come up? Also please repeat with "nxagent -R -ac :55". (no nxagent window will come up, the xterm should open up in its own window in step 2) Uli On Fri, Mar 10, 2023 at 11:53 AM Kalle Tuulos wrote: > > Hi Ulrich > > In this client log, I have defined Session type as Single application and > command as "/usr/bin/xterm". > > ---8<---8<--- > kalle@cathouse:~$ x2goclient --libssh-debug > qt.qpa.xcb: X server does not support XInput 2 > x2go-INFO-1> "Starting X2Go Client 4.1.2.2..." > x2go-WARNING-1> English language requested, not loading translator. > x2go-WARNING-1> English language requested, not loading translator. > x2go-INFO-3> "Started X2Go Client." > qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, > resource id: 309, major code: 130 (Unknown), minor code: 47 > x2go-INFO-8> "Starting connection to server: 192.168.1.41:22" > [2023/03/10 12:50:28.963355, 1] ssh_config_parse_line: Unsupported option: > ServerAliveInterval, line: 2 > [2023/03/10 12:50:28.963385, 2] ssh_config_parse_line: Unapplicable option: > ForwardX11Trusted, line: 5 > [2023/03/10 12:50:28.963393, 2] ssh_config_parse_line: Unapplicable option: > ForwardX11, line: 6 > [2023/03/10 12:50:28.963439, 2] ssh_config_parse_line: Unapplicable option: > SendEnv, line: 50 > [2023/03/10 12:50:28.963447, 1] ssh_config_parse_line: Unsupported option: > HashKnownHosts, line: 51 > [2023/03/10 12:50:28.963469, 2] ssh_connect: libssh 0.9.3 (c) 2003-2019 Aris > Adamantiadis, Andreas Schneider and libssh contributors.

Hi,
if you are not using kdrive then this message is totally ok.
The log does not show a real problem, AFAICS. So can you please try to
configure a minimum session opening only an xterm, again without any
file sharing, printing, sound?
