On a long-running session that I've been connecting to / disconnecting for many times, this morning I'm getting the attached error message. Despite the error message, the x2go session seems to still be working. This is Fedora 31 linux client + server. x2goclient-4.1.2.1-4.fc31.x86_64

How to run a script that needs a terminal initially but is then a GUI (as a single application)?
by Chris Green 29 Dec '19

29 Dec '19

I discovered x2go a year or so ago and I'm finding it very useful, thank you! :-) I'm running x2go client on an xubuntu 19.04 system and the server on an xubuntu 19.10 system. I have a short script on the server system which first runs encfs to create a file system and it then runs a GUI that uses the file system just created. How can I run this as a 'Single application' in x2go? The script is called 'digimax', I have tried running a terminal as the single application by putting the following command into x2go:- xfce4-terminal -x /home/chris/bin/digimax This successfully asks for the encfs password in the terminal window that appears but it then just disappears and no GUI app follows. The script /home/chris/bin/digimax works perfectly when run locally in a terminal window. Is there any way I can get x2go to run this for me as a single application? -- Chris Green

X2Go, Debian, Openbox - How run graphical clients as a simple user
by Lmhelp1 27 Dec '19

27 Dec '19

Hello, I am using X2Go under Debian with Openbox. I have upgraded to Debian Buster, I didn't use to experiment the problem below with Debian Stretch. My problem is about running graphical clients (like xeyes, xterm, gvim, etc.) from a console logged in either as a "simple" user ("user_2" below) or as "root". "user_2" cannot run these clients, "root" can. I would like both of them to be able to run these clients. Below, is what happens ("user_1" is the user that started the X2Go session, it is also a "simple" user). user_1> su user_2 Password: No protocol specified xrdb: Resource temporarily unavailable xrdb: Can't open display ':50' user_2> exit user_1> su Password: root> xeyes <OK> Can you tell me how to allow "user_1" to run graphical clients like xeyes, xterm, gvim, etc.? Best regards, -- Léa

New (unofficial) openSUSE packages available
by Tristan Miller 16 Dec '19

16 Dec '19

Greetings. The official X2Go RPMs for openSUSE have been broken or missing for many months. (See Bugs 1358, 1360, 1403, and 1427, as well as numerous problem reports on this mailing list over the past year.) Essentially it is no longer possible to install X2Go on openSUSE Leap and openSUSE Tumbleweed using the RPMs provided by X2Go. (And if you happen to have X2Go already installed, it is not possible to upgrade your openSUSE system without removing X2Go.) I suppose the developers are too busy to fix this problem, so I have built openSUSE RPMs of x2goclient, x2goserver, and pinentry-x2go myself using the latest SCM versions: openSUSE Leap 15.1 packages for x86_64: <https://download.opensuse.org/repositories/home:/psych0naut:/x2go/openSUSE_…> openSUSE Tumbleweed packages for i586 and x86_64: <https://download.opensuse.org/repositories/home:/psych0naut:/x2go/openSUSE_…> I have not contributed packages for openSUSE Leap 15.0 as that distribution reached end of life earlier this month. However, if anyone really needs those packages, let me know and I can see if I can get the openSUSE Build Service to produce them. Similarly, if anyone needs any other X2Go packages for openSUSE Leap 15.1/Tumbleweed, let me know and I may be able to contribute these as well. Note that I do not have any sort of automated system in place for keeping these builds in sync with the latest commits to X2Go. I consider my builds to be a stopgap measure until the X2Go developers fix their own nightly build system.

Cursor key mappings sometimes break on reconnect
by Hanno Foest 10 Dec '19

10 Dec '19

Hello, I currently have the problem that my long-running x2go session works just fine, but after several weeks the cursor key mappings are suddenly garbled after re-connecting the session, and stay that way. The only way to "fix" the issue seems to be restarting it. Right now only cursor down works, and does the same thing as the Enter key. Cursor up, left and right are without function. I had a similar issue for at least 2 years before, where the Del key stopped working. That scenario seems to have been replaced by the one with the cursor keys for the last few months. (I'm just noticing that there seem to be even more issues - the Del key is now Print, and AltGr beeps. Usually I restart the session very soon, because it's not good to work with a misbehaving keyboard, so I didn't notice these before.) I *think* the problems start when re-connecting the session takes a few seconds longer than usually, but it's hard to tell because the issue happens rarely and infrequently. remote: Ubuntu 16.04.6 LTS x2goserver 4.1.0.3-0~1708~ubuntu16.04.1 local: Devuan GNU/Linux 2.1 (ascii) x2goclient 4.1.2.1-0x2go1+git20180626.1801+8.main.1 Redefining the keyboard settings with setxkbmap does not help. Output from xmodmap -pk with or without the issue present doesn't show a difference. xev -even keyboard has some interesting output though, see https://pastebin.com/kKEgeSDB And indeed, my AltGr key now works as cursor left, as far my current x2go session is concerned. I would be happy if someone had an idea how to reset my key mappings without restarting the session. But if I could help debugging the issue for good, that would be nice, too :) Hanno

Cannot launch GThumb (double free or corruption)
by Nicolas Ecarnot 09 Dec '19

09 Dec '19

Hello, User since long of x2go, I'm now facing the following issue : - client host is XUbuntu 19.10, with a 4.1.2.1-2 client - server host is XUbuntu 19.10, with a 4.1.0.3-4 server Everything sounds good and I can do basically anything I want (things are responsive, colours are OK, aso...) But when running the images viewer "GThumb", the software is not launching and stops with the following error : double free or corruption (!prev) Abandon (core dumped) Obviously, I made my homeworks and search around for clues. Though I find many similar cases with people having the same issue, it doesn't seem specifically related to x2go not gthumb. BUT... Yet I send this message here because my target server is also a workstation I use everyday *not remotely* and on which I can perfectly run gthumb. Should I look at some colour depth settings, at missing libraries, or could anyone lead me to some precise x2go settings I could tweak? Thank you. -- Nicolas
