Mac Lion
by Robert Dinse 15 Apr '15

15 Apr '15

I recently had need to boot into MacOS Lion (10.7.5) and while I had it running downloaded the most recent X2Go client. I am happy to report the inverted CAPS LOCK key is fixed in the latest version. Unfortunately sound still does not work. I've still got ESD only under MacOS and haven't attempted to compile Pulse Audio yet (and probably won't since I rarely use MacOS anymore). -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

X authorization issues
by Christoph Schmidt-Hieber 10 Apr '15

10 Apr '15

Dear all, We're having issues connecting to an x2go server running on Debian Wheezy. Specifically, we cannot connect to an xfce4 desktop from an OS X client. The x2go client version is 4.0.3.2 (from MacPorts). The x2go server version is 4.0.1.19-0x2go2+git20150326.1064+wheezy.main.1 (from the x2go Debian repo) Connections using plain "ssh -Y" or "ssh -X" work fine. Connections with x2go to a single application work fine. The permissions of $HOME/.Xauthority are 600 The owner of $HOME/.Xauthority is $USER:$USER The first attempt to connect will simply fail, without valuable error messages (at least to me), the second attempt will result in: "Your session was closed before reaching a usable state. This can be due to the local X server refusing access to the client. Please check authorization provided by the remote X application." Debug output from the client is attached. Any help would be greatly appreciated. Christoph

Ok. Can you please check that x2goserver-xsession is installed? I suspect this is not the case. Mihai

WorkSpace Switching
by Robert Dinse 10 Apr '15

10 Apr '15

I spoke too soon, the control-alt-left-arrow or control-alt-right-arrow to switch workspaces when you have an x2go client in them works sometimes. It seems to initially not work, but when you use control-alt-m to minimimize, after it's restored, then the other keys work. This is under Ubuntu with a MatÃ©desktop. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

GNOME and Unity can not launch
by Heng Zhou 09 Apr '15

09 Apr '15

Hi, I installed the latest X2Go client, but it only works with KDE. When I tried to launch Unity and GNOME desktop, they always fail. To be specific, when I selected Unity, the desktop just flashes and disappear. When I selected GNOME, I got a black desktop window and VcXsrv reports an error saying "Cannot establish any listening socket - make sure an X server isn't already running". The contents of VCXSrv.0.log is: _XSERVTransSocketCreateListener: failed to bind listener _XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: failed to create listener for inet6 _XSERVTransSocketCreateListener: failed to bind listener _XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: failed to create listener for inet (EE) Fatal server error: (EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE) (EE) Server terminated with error (1). Closing log file. I have no idea how to check if any X server is running on my computer. All the settings of X2Go are default. The remote machine is ubuntu 14.04. Any help? Thanks.

x2goserver issue on Ubuntu precise ...
by Sylvain Milot 09 Apr '15

09 Apr '15

Hello everyone, I have the following on my client when I connect to a server running the same ubuntu precise distribution: $ cat .x2go/S-sylvain-52-1428522297_stDXFCE_dp24/sessions Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. $ lsb_release -d Description: Ubuntu 12.04.5 LTS $ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t nxproxy 2:3.5.0.31-0~605~ubuntu12.04.1 x2goagent 2:3.5.0.31-0~605~ubuntu12.04.1 x2goclient 4.0.3.2-0~800~ubuntu12.04.1 x2goserver 4.0.1.19-0~1064~ubuntu12.04.1 x2goserver-extensions 4.0.1.19-0~1064~ubuntu12.04.1 x2goserver-xsession 4.0.1.19-0~1064~ubuntu12.04.1 Has anyone encountered this ? I had this working at some point and it appears a regression may be at play on the server side. I googled the problem and it seems to have been reported many years ago so perhaps someone on this list can provide some quick insight? On my ubuntu server (also 12.04.5) I have the following : $ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t nxproxy 2:3.5.0.31-0~605~ubuntu12.04.1 python-six 1.8.0-1~bpo70+1~0x2go~ubuntu12.04.1 x2goagent 2:3.5.0.31-0~605~ubuntu12.04.1 x2goclient 4.0.3.2-0~800~ubuntu12.04.1 x2goserver 4.0.1.19-0~1064~ubuntu12.04.1 x2goserver-compat 4.0.1.19-0~1064~ubuntu12.04.1 x2goserver-extensions 4.0.1.19-0~1064~ubuntu12.04.1 x2goserver-xsession 4.0.1.19-0~1064~ubuntu12.04.1 I changed loglevel=debug on the x2go server to look for clues but nothing caught my attention. Note that with the same client (running at home) I can connect to other servers running Debian squeeze, on the same network as the ubuntu precise server (at work). On my debian squeeze servers, I have this ... all works nicely here though: $ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t libnx-x11 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 libssh-4 0.5.4-2~deb6+x2go2 libxcomp3 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 libxcompext3 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 libxcompshad3 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 nxagent 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 nxproxy 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 rdesktop 1.7.1-0~bpo60+x2go1 x2go-keyring 2012.07.23+squeeze~main~17~build1 x2goagent 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1 x2goclient 4.0.3.1-0x2go1+git20141127.753+squeeze.main.1 x2godesktopsharing 3.1.1.1-0x2go1+git20140401.131+squeeze.main.1 x2goserver 4.0.1.18-0x2go1+git20141006.949+squeeze.main.1 x2goserver-compat 4.0.1.18-0x2go1+git20141006.949+squeeze.main.1 x2goserver-extensions 4.0.1.18-0x2go1+git20141006.949+squeeze.main.1 x2goserver-xsession 4.0.1.18-0x2go1+git20141006.949+squeeze.main.1 Thanks in advance for any help and x2go is a great piece of software BTW!

Re: [X2Go-User] Fwd: Ctrl-s not recognised (OS X client)

Starting up xev will likely put it into foreground and every X11 event is printed out verbatim. Make sure the pointer doesn't move, or you will be spammed with messages. Pressing Ctrl will print a message with "Control_L" on the third line. Afterwards, pressing "s" (hold Ctrl all the time) will print a message having "s" in the third line and the fourth line will read XLookupString gives 1 bytes: (13) "" if everything is working as expected. Given that the key combination is not recognized in emacs and LibreOffice, I suspect nothing will pop up in xev. However, my basic test suggested that it's not a general X2Go problem, as it's working on my machine(s) and I know a few users using LibreOffice via X2Go. Naturally, Ctrl-S not working would be a grave issue for them. My current suspicion is that the keypresses are either captured by a desktop environment or NX. I understand that you have no control over the remote system as such, but, if existent, what is the content of /etc/nxagent/keystrokes.cfg? Mihai

Ctrl-s not recognised (OS X client)
by Christopher Thomas 08 Apr '15

08 Apr '15

Hi, I connect to my university servers remotely from OS X using x2go. It seems that the keystroke combination Ctrl-s (and perhaps some other combinations) are not recognised. This is quite inconvenient, particularly since I use emacs extensively and Ctrl-s is the command for a search. I couldn't find any info on this problem. Can anyone help? Chris

OSX/windows keyboards?
by Les Mikesell 07 Apr '15

07 Apr '15

When I start a remote linux session from an OSX client, then disconnect and pick up the session from a windows client, the screen seems OK but the keyboard input is garbage. I thought I had that problem a long time ago and then it was fixed. Do the client versions have to stay in sync? And is there some way to reset the keyboard type to fix it and continue the session? -- Les Mikesell lesmikesell(a)gmail.com
