Runlevel 5 needed?
by Markus Kuderer 19 Apr '13

19 Apr '13

Hello everybody, in the installation instructions there is a remark that the server has to be run runlevel 5 to allow the X2Go server to accept connections. Why is it like this? Is the local XServer needed for operation? Is there an easy way to overcome this? Background of my question: I'm interested in using X2go in our system, but we had to switch to runlevel 3. Actually we use mainly VNC sessions for remote operation and these tended to hang up with a "local" XServer running on the server. Thank you very much. Best regards, Markus

issue: GTX don't work with V.4.0.0.1
by Michael Korn 17 Apr '13

17 Apr '13

Hello, I'm using Ubuntu 12.04 and a GTX 680 (Driverversion: 304.48) The old x2go (3.) worked with different 304.xx versions. Since I updated to 4.0.0.1 OpenGL/GLX don't work in a remote session any more. e.g.: > korn@cuda1:~$ glxinfo | grep direct > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Error: couldn't find RGB GLX visual or fbconfig > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". > Xlib: extension "GLX" missing on display ":52.0". Locally it works! Any ideas? Thanks Michael

Anyone installed/used the new x2goplugin on Windows yet?
by brian mullan 15 Apr '13

15 Apr '13

I was able to get the new x2goplugin working on linux with multiple different web browsers but the last I checked the x2go wiki was looking was still looking for input on how to install the x2goplugin on both Windows and Mac. Has anyone done this successfully yet? If so could they post how they set things up? thanks Brian

Debugging tips?
by Tom Harris 15 Apr '13

15 Apr '13

I'm just starting to use x2go, and it has mostly worked great. But, I have run into problems where I connect to my server, get authenticated, but never get my application displayed. I can see the x2goagent process running on the server, but the app never displays. Creating a new user account and logging in with that has usually succeeded as a workaround. But, obviously that's not a solution. I'm sure there is a simple fix for this, like cleaning up some lost session data. But, my attempts thus far have failed. Are there any session debugging tips available? Or, pointers for where to look or how to enable more debugging output?

Custom login script user/pass variables and pyhoca-cli
by Jonathan Brown 12 Apr '13

12 Apr '13

Hello I have two versions of a script that log a thin client into an x2go server using a YAD graphical prompt which passes variables to pyhoca-cli. The following works fine and logs you right in after entering AD username and pass: ----------------------------- #!/bin/bash while true; do frmdata=$(yad --center --undecorated --image=/usr/share/wallpaper/sago-header-mod.jpg --image-on-top --button="gtk-ok:0" --title "Login to Sago Linux Terminal Server" --form --field="AD username" --field="Password:H") frmusername=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $1 }') frmpassword=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $2 }') pyhoca-cli --server 10.0.201.242 -u $frmusername --password $frmpassword -c startkde --sound none --kbd-layout us --kbd-type pc105/us -g fullscreen --add-to-known-hosts done ---------------------------------- However, this one, which adds a dropdown to choose a session, does not just log in, it asked for interactive login at the console..

x2go with OS X and Proxy Server
by senrabdet＠aol.com 11 Apr '13

11 Apr '13

Hi All: Has anyone been using x2go on OS X using the proxy server option? We can get things to go just fine from a Windows machine (we are using two ssh keys, and in authorized_keys on the server direct the connection from the proxy server to an internal one). However, when we try the same settings on the OS X x2go interface, the connection sits there and never gets passed a status of "connecting". Any help appreciated! Thanks, Ted

Local Desktop Session with two monitors
by Tobias | x2go-community.org 10 Apr '13

10 Apr '13

Hi, is it possible to connect a local desktop session where the user we are connecting to has a two monitor desktop? The user gets a two monitored x2go session _but_ one monitor of the screen stays black and there is no interaction possible. http://x2go-community.org/node/36 "export DISPLAY=:50;printf '3839 0 1 1080\\n0 0 1919 1080\\n1919 0 1920 1080' > ~/.x2go/C-belladonna-50-1365404275_stS1XSHADbelladonnaXSHADPP0_dp24/xinerama.conf" tobias

got a black window after login and then disconnected automatically
by zimy 09 Apr '13

09 Apr '13

Hello, I use x2goclient to connect to a ubuntu 12.04 server machine with gnome installed. It worked well before I recently updated it. I remembered the updating related to ssh, and now I cannot connect it with x2goclient. I got a black window, and later x2goclient disconnected automatically. I tried x2goclient installed on a Win XP and Unbuntu 12.04. All failed. So the problem should be on the server side. The x2goserver/x2goclient are all the latest version. The information printed from the client side is attached. I saw nothing abnormal. Do you have any ideas?

Current Mac x2goclients crash
by Jonathan Fosburgh 08 Apr '13

08 Apr '13

I have attempted to run the 4.0.0.4 and 4.0.1.0 builds of x2goclient on my MacBook Pro (OS version 10.7.3). Both of them crash immediately on launch. When attempting to run from the command line I get illegal instruction 4. Unfortunately, I have not used a Mac long enough to know how to troubleshoot this (though I do have an extensive UNIX/BSD/Linux background) beyond the basics outlined below. For the 4.0.1.0 build, I have verified the md5 sum matches. I have the .dmg files for the 4.0.1.0 and 3.99.2.1 builds mounted. One thing I notice is that 4.0.x is significantly smaller than 3.99: /dev/disk1s2 50272 50272 0 100% /Volumes/x2goclient /dev/disk3s2 223104 188328 34776 85% /Volumes/x2goclient 3.99.2.1 Are the newer builds expected to be this much smaller? Unpacked, the entire dmg for 4.0.x is about 70MB smaller than the actual space used by 3.99.x, even with the dmg for 3.99 being somewhat bigger than the amount of space required.

x2goclient sessions immediately exit
by Orion Poplawski 06 Apr '13

06 Apr '13

One of our x2gousers is having problems where sometimes it seems to get stuck in a mode of connecting, the screen displays briefly, and then it exits (suspends). I've turned on debugging on the server but no error messages. Using pretty much the most recent stuff built for Fedora 18 and 17 (my own rpms). -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion(a)cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com
