07 Nov '17

Hello, I have two problems with two IDEs. 1) For R programming I use Rstudio.I am starting mate-terminal via x2go, and then execute rstudio remotely. It displays well, apart from the fact that pull-down menus are not displayed. They got highlightedwhen clicked, but nothing more. This is the only program which has this issue that I am aware of. Warning messages are as follows: QXcbConnection: Failed to get the primary output of the screen Could not initialize OpenGL for RasterGLSurface, … [View More]

ssh-keygen.exe loads the processor every time the client starts
by Max A. 07 Nov '17

07 Nov '17

Hello. I'm using a x2go server on CentOS 6.9 (the latest version from EPEL, 4.0.1.20), clients use Windows XP/7 and the latest version of X2Go Client (4.1.0.0-2017.03.11). Each time the client connects, ssh-keygen.exe (C:\Program Files\x2goclient\ssh-keygen.exe) starts with the parameters "-t rsa -b 4096 -N" "-C" X2Go Client RSA user key "-f C: /Users/max/.x2go/ssh/gen/key.fl1416 ". On not very powerful computers, this causes a delay of a few seconds with each connection and irritates … [View More]

X2Go on Debian Stretch server : root user keyboard mapping
by Bruno Joffredo 06 Nov '17

06 Nov '17

Hello, I have installed X2Go (server v4.0.1.20) on a Debian Stretch (v9.2) server a few days ago. This machine is secured at the network level, so i want to login root. When I log in as a user, the keyboard mapping is good. But when I log in root, the arrow keys are not good : up doesn't show anything, down acts like return, and the pipe key does not show anything. I did some search on the web, but everything I found did not work. Connected via X2go Client to the root user : * the … [View More]command setxkbmap fr return : Error loading new keyboard description * echo $DISPLAY : :50.0 * the command DISPLAY=:0.0 setxkbmap fr return no error * here is the contents of the file ~/.x2go/C-root-50-1509957528_stDLXDE_dp24/clients : No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24 No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24 No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24 No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24 No matching visual for __GLcontextMode with visual class = 5 (32771), nplanes = 24 No matching visual for __GLcontextMode with visual class = 5 (32771), nplanes = 24 No matching visual for __GLcontextMode with visual class = 5 (32771), nplanes = 24 No matching visual for __GLcontextMode with visual class = 5 (32771), nplanes = 24 The XKEYBOARD keymap compiler (xkbcomp) reports: > Error: Can't find file "null" for symbols include > Exiting > Abandoning symbols file "default" > Error: Cannot open "compiled/server-50.xkm" to write keyboard description > Exiting The XKEYBOARD keymap compiler (xkbcomp) reports: > Error: Cannot open "compiled/server-50.xkm" to write keyboard description > Exiting The XKEYBOARD keymap compiler (xkbcomp) reports: > Error: Cannot open "compiled/server-50.xkm" to write keyboard description > Exiting AUDIT: Mon Nov 6 09:38:52 2017: 27087 x2goagent: client 3 rejected from local host The XKEYBOARD keymap compiler (xkbcomp) reports: > Error: Cannot open "compiled/server-50.xkm" to write keyboard description > Exiting * I modified the content of the file /etc/x2go/x2goagent.keyboard like that : rules=evdev but it's always the same I don't know what to do.

Mint Sonya 18.2
by Robert Dinse 06 Nov '17

06 Nov '17

I upgraded Mint from Serina to Sonya 18.2 and now with x2go I am getting the tiny 680x800 screen related to xrandr version being 1.2 where 1.3 or later is needed. I installed the nightly build which has corrected this problem on other distributions but it did not fix it in mint.

X2Go and a complex command
by James M. Pulver 01 Nov '17

01 Nov '17

I'm having some issue with a session command. I'm trying to launch x2go and have it run xterm -e 'qrsh -q interactive.q -pe sge_pe 1 -l m_core=1 /nfs/opt/ImageJ/ImageJ' This command works when run manually, and other commands like xterm -e 'qrsh -q interactive.q -pe sge_pe 1 -l m_core=1 matlab -desktop' work also.
