Global ssh-agent
by Dmitry Bely 03 Dec '15

03 Dec '15

Hi, I would like to use ssh-agent globally for X session (Debian/MATE if it matters). X session starts it itself and when I login to X locally it works as expected (SSH_AGENT_PID and SSH_AUTH_SOCK environment variables are set correctly). But if I connect to the host via x2go, strange things happen: in any terminal session SSH_AUTH_SOCK points to non-existing path and SSH_AGENT_PID is not set at all. I tried to work around this adding to ~/.bashrc: if [ ! -S ~/.ssh/ssh_auth_sock ]; then eval `ssh-agent -s` ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock fi export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock This way SSH_AUTH_SOCK is correct but SSH_AGENT_PID is surprisingly unset somethere. Any idea how to fix that? - Dmitry Bely

Hi Stefan! The adding extra spaces before and after "/" are from google translator. I have not seen that after copying / before paste the text, sorry. Thank you for "TC_X2GO_DEBURL = deb http://packages.x2go.org/debian wheezy main" It works now. Bye, Olaf (PS: I am not sure if this posting will be there at the correct place, in the thread. I did not receive any mail after the Authorization-Mail, and I do not see any "reply"-Button on this gmane-page.)

Re: [X2Go-User] Debian Jessie + Openbox / Not working keyboard shortcuts

Hi René, Thank you for your answer. > does ctrl+alt+tab work for you to switch windows? Unfortunately not. [X2Go client is installed on a Windows OS.] [X2Go server is installed on a Debian Jessie OS.] [The session is an OpenBox session.] ctrl+alt+tab allows me to switch from one Windows OS window to another... Thanks for helping. Best regards, -- Léa Massiot On 2015-12-01 8:59 AM, René Genz wrote: > Hi Léa, > > does > ctrl+alt+tab > work for you to switch windows? > At least that is my workaround in my X2Go sessions (X2Go client on > Lubuntu 14.04 x86; X2Go server on Fedora 22 x86_64; Xfce session).

Debian Jessie + Openbox / Not working keyboard shortcuts
by Lmhelp1 30 Nov '15

30 Nov '15

Hello, I am using Debian Jessie + Openbox. When logged into the machine itself (not via X2Go), I usually hit the keyboard keys Meta + t to start a new XTerm. To be able to do this, I added the following keybind into the OpenBox configuration file "/etc/xdg/openbox/rc.xml": ======================================== <keybind key="W-t"> <action name="Execute"> <command>xterm -fn 10x20</command> </action> </keybind> ======================================== Hitting Meta + t, successufully starts a X terminal. Also, I can hit: Ctrl + Alt + F1 to F6: to switch to the first to the sixth console. Ctrl + Alt + F7 : to switch to desktop mode. These keyboard shortcuts do not work when I am logged into the machine via a X2Go client. Is there something I can do to make these shortcuts work? Thank you and best regards. -- Léa Massiot

Hello I've not been able to get remote print working. The issue seems to be with this: # ls -l /tmp/.x2go-rob/spool ls: cannot access /tmp/.x2go-rob/spool/C-rob-63-1448653826_stDLXDE_dp24: Permission denied total 0 d????????? ? ? ? ? ?

Any clues on how to solve this? best regards Rob Fantini

Hello I've been using Jessie and Mint on virtual machines and on hardware, but can not seem to get remote print working - due to an sshfs issue. I posted in an earlier email a few days ago. If you have remote print working, could anyone please report back which distro / release works? best regards, Rob Fantini

Putting the below in /etc/sysctl.conf both client and server machine, helped me a whole lot.

TCE client resolution
by Michael Pope 30 Nov '15

30 Nov '15

I'm running an Intel D510MO with Intel graphics chipset as my x2go thin clients. When I start my session and set my display to 1920x1080 for the 24" screen I notice that a lot of the screen is hidden off the sides and top and bottom of the screen. I'm missing a good 100px right around. Here is my sessions file; [20130619111118075] speed=4 pack=16m-jpeg quality=9 fstunnel=true export= iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=true width=1920 multidisp=false display=3 height=1080 dpi=96 setdpi=false xinerama=true usekbd=true layout=us type=pc105/us sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=myserver icon= host=192.168.0.4 user= key= sshport=22 autologin=false krblogin=false rootless=false published=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL, startxfce4, xfce4-session, /usr/bin/openbox command=XFCE rdpoptions= rdpserver= xdmcpserver=localhost maxdim=false rdpclient=rdesktop directrdpsettings= rdpport=3389 directrdp=false usesshproxy=false sshproxytype=SSH sshproxyuser= sshproxykeyfile= sshproxyhost= sshproxyport=22 sshproxysamepass=false sshproxysameuser=false sshproxyautologin=false krbdelegation=false sshproxykrblogin=false clipboard=both If I set the resolution to 1280x1080 it fits ok, but as it's the wrong ratio for the screen it looks a little funny and I would prefer 1920x1080 if possible. I've been happy using this client in 1920x1080 as a LTSP thin client so I know it all works from Michael

TCE install a new kernel
by Michael Pope 30 Nov '15

30 Nov '15

I've just installed the Thin Client Environment on a separate Debian VM and some of my clients boot. Some need a more up to date kernel than 3.2, I would like to use the 3.16 kernel from backports under Debian Wheezy. I've installed the 3.16 in the chroot environment and ran the x2go update script, but my thin clients still boot with the 3.2. Is there something else I have to do? Here is the list of commands I did; Go into chroot environment : x2gothinclient_shell Install latest kernel 3.16 : apt-get -t wheezy-backports install linux-headers-3.16.0-0.bpo.4-amd64 linux-headers-3.16.0-0.bpo.4-common linux-image-3.16.0-0.bpo.4-amd64 Exit chroot environment and update : exit : sudo x2gothinclient_update from Michael
