x2goclient session icons not working
by Will Wagner 23 Nov '16

23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

remote development environment
by Raphael Bauduin 17 Nov '16

17 Nov '16

Hi, I have no experience with x2go but it seems to be a good fit to implement a remote development environment. Does anyone here have experience with such a setup? (Read below for more details) I need to set up a remote development environment to be used by multiple employees of a company. The goal is to let employees work in their prefered environment. As users might need to have root access, I might go with one vm per user. That would effectively move the desktop system of the user to the 'cloud', which would be access through x2go. That way every dev can use the editor (s)he wants, compile on its vm, install packages, etc... Would that be a workable approach? Which attention points would you highlight? If anyone has experience with this kind of setups, I'm very interested in getting your advices and opinions! Thanks in advance rb

Re: [X2Go-User] Clipboard and virt-viewer?

I don't run anything like that normally, but I have this feeling that virt-viewer does something that might resemble a clipboard manager so it can capture the selection and send the info about it into the virtual machine. I know the virtual machine needs to be running an "agent" service to talk to the outside world via a virtual serial port (or something like that, anyway - I'm very fuzzy on the details :-). Of course I'm also fuzzy on the details about how x2go deals with selections, so that's fuzzy squared :-).

Issues with resuming session
by Bragg, Richard 16 Nov '16

16 Nov '16

Trying to move from NoMachine as new server is virtual and I'm having some issues with some programmes not resuming with correct colours. Client : 4.0.5.2 (Qt 4.8.6) Windows 7 32 bit Server info - OpenSuse 13.2 KDE 4 On intial startup it works fine. It would be good if it would, like NoMachine, always use the 4:3 moitor if attached whether 1st or 2nd display device. But I set it to use display 2 for testing. Session starts full screen as expected and I can background the screen and bring back to front. On resume : If I use the internal X server a window open then crashes. If I use the latest build of vcsvr it will start up but in a small window and this doesn't resize or rather the window resizes but the display doesn't. I move to larger monitor and the display only takes up half height.

More than emacs crashes now
by Tom Horsley 16 Nov '16

16 Nov '16

I'm sure I've run virt-manager and virt-viewer under x2go fairly recently, but some update has apparently killed lots of things sometime recently: virt-manager and virt-viewer crash when run under x2go. zooty> gdb /usr/bin/python2 GNU gdb (GDB) Fedora 7.11.1-86.fc24 Copyright (C) 2016 Free Software Foundation, Inc.

Adding old style fonts to X server?
by Tom Horsley 13 Nov '16

13 Nov '16

I use x2go frequently between my fedora linux system at work and my near identical fedora linux system at home. When using X directly on both systems I get a font path like: Font Path: catalogue:/etc/X11/fontpath.d,built-ins And the /etc/X11/fontpath.d directory has lots of symlinks to various font directories (with most of the same fonts installed on both systems). When using x2go, I see the font path is much stupider. Including explicit paths to just the misc, 100dpi, and 75dpi font directories. What the heck is the bast way to fix this so old X programs will see all the same fonts I get when I run native? Can I do something like edit /etc/x2go/x2goagent.options and add -fp catalogue:/etc/X11/fontpath.d,built-ins as an option? (On both source and target systems).

Clipboard and virt-viewer?
by Tom Horsley 13 Nov '16

13 Nov '16

On my native fedora box, if I'm looking at a virtual machine display in virt-viewer, I can use cut&paste to do something like copy the current URL from a web browser running on the host machine, and paste it into a web browser running inside in virtual machine in the virt-viewer display. If I'm connected to the same fedora box remotely via x2go, and I then display a virtual machine inside that remote x2go session, the cut&paste from fedora to virt-viewer doesn't work. Any idea what is going on here and how to make it work?

terminating suspended sessions
by Sebastian T. 04 Nov '16

04 Nov '16

After some time unclosed sessions fill all the memory on the server. It is hard to discipline users to always close sessions -they just close the client instead. Is there any more elegant way of clearing all suspended sessions then the command I have here: for f in `/usr/sbin/x2golistsessions_root |grep \|S\| | cut -c-5`; do /usr/ bin/x2goterminate-session "$f" && kill "$f";done

Segfault on some applications
by Thackeray, Neil L 04 Nov '16

04 Nov '16

I just upgraded Ubuntu from 14 to 16.04, and I really regret it now. Many things now don't work within X2go. I've completely lost KDE, which I see is a known issue, but for some reason now Firefox and many other applications don't work. I even tried gnome-calculator and it doesn't work now, but LibreOffice does. I'm not sure if it's because of the graphical toolset used or not. The most important app not working for us is Eclipse. All of the applications that don't work function fine with an exported X session, but there is just something in X2go that is keeping it from working. kernel: [12762.555968] firefox[65546]: segfault at 0 ip 00007f9d91f649bf sp 00007ffecd72a238 error 4 in libc-2.23.so[7f9d91ecf000+1bf000] kernel: [12762.572675] crashreporter[65553]: segfault at 0 ip 00007f4bf9c009bf sp 00007ffe73a9d248 error 4 in libc-2.23.so[7f4bf9b6b000+1bf000] kernel: [12787.466816] [UFW BLOCK] IN=eth0 OUT= MAC=01:00:5e:00:00:01:00:25:00:ef:46:fb:08:00 SRC=128.174.227.254 DST=224.0.0.1 LEN=44 TOS=0x00 PREC=0x00 TTL=1 ID=63656 PROTO=UDP SPT=52742 DPT=8612 LEN=24 kernel: [12800.095585] gnome-calculato[65714]: segfault at 0 ip 00007fcfab8999bf sp 00007ffd744e1ff8 error 4 in libc-2.23.so[7fcfab804000+1bf000] kernel: [13492.855643] eclipse[68620]: segfault at 0 ip 00007f4bca47c9bf sp 00007ffd8d26b2b8 error 4 in libc-2.23.so[7f4bca3e7000+1bf000]
