Emacs crashes on start
by Roderick Johnstone 18 Sep '17

18 Sep '17

Hi I'm connecting from a Mac (X2Go Client v. 4.0.5.1 (Qt - 4.8.7)) to Fedora 24 with a xfce session using the x2goserver-4.0.1.19-11.fc24.x86_64 packages from the fedora repos. On starting emacs, I get the error below. This issue seems to have been around for a while in similar forms, but didn't affect me under Fedora 22. Is anyone in a position to confirm this issue on Fedora 24 and suggest a work around? I tried setting various environment variables suggested on various web pages for similar issues and in the bug report noted in the error message (and checked /etc/PROBLEMS), but nothing was effective. emacs starts fine in an xfce session at the console. Thanks Roderick Johnstone X protocol error: BadRequest (invalid request code or no such operation) on protocol request 131 When compiled with GTK, Emacs cannot recover from X disconnects. This is a GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=85715 For details, see etc/PROBLEMS.

Logging x2go connections?
by Grigory Shamov 04 May '17

04 May '17

Hi All, This perhaps is a trivial question: but is it possible to somehow log/check history of past x2go session on the server? -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

Shared Folders?
by KARL A. WOELFER 25 Jan '17

25 Jan '17

I am not able to get the basic Shared Folder capability to run. Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop. Is there something fundamental preventing this from working? Thanks in advance, - KarlW

Num Lock key in windows agent
by Olivier BILHAUT 24 Nov '16

24 Nov '16

Hi all. First of all, I'd like to congratulate all the contributors for this great work. X2go is a professional class tool for remote desktop. However... I ran into a really special thing using the windows agent in its last version (4.0.5). Sometimes, when you open the session, the "Num Lock" is usable, sometimes not. I mean, sometimes you may push the caps lock button and switch from arrows to Numeric keys, and sometimes the Key Pad is fully unusable. It happens only on windows agent as far as I know. All that I tried did not solve the issue. Did you already encounter that? Thanks. -- OB SySAdmin Fondation Hospitalière de la Miséricorde

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

Upcoming Deprecation of EOL Distributions
by Mihai Moldovan 03 Nov '16

03 Nov '16

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have reached End Of Life on September 4th 2016. This includes the following distro versions: - Debian: o 6.0 "squeeze" - Fedora o 19 o 20 o 21 o 22 - OpenSuSE o 12.2 o 12.3 o 13.1 - SuSE Linux Enterprise Desktop (not Server!) o 11.2 o 11.3 After deprecation, no new builds will be published and existing builds will be deleted from the repositories to discourage users from installing unmaintained software.

Re: [X2Go-User] x2go hang on CentOS7
by Chris Collins 05 Sep '16

05 Sep '16

Hi, Just a quick update on this (I've not resolved it unfortunately).... I thought I'd try the git version RPMs rather than the EPEL el7 versions, so I'm now running: x2goserver-extensions-4.0.1.19-0.0x2go2.1.git20160621. 1064.main.el7.centos.x86_64 x2goserver-xsession-4.0.1.19-0.0x2go2.1.git20160621.1064. main.el7.centos.x86_64 x2goserver-4.0.1.19-0.0x2go2.1.git20160621.1064.main.el7.centos.x86_64 x2goagent-3.5.0.32-0.0x2go1.1.git20160615.734.main.el7.centos.x86_64 Again, just trying to start xterm. When I try connecting the client 'hangs' and on the server (with log set to debug) I get the following, which continues until I start killing pids: Aug 24 10:35:31 login02 sshd[12844]: Accepted publickey for chris from <my machine> Aug 24 10:35:31 login02 systemd-logind: New session 3776 of user chris Aug 24 10:35:31 login02 systemd: Started Session 3776 of user chris Aug 24 10:35:31 login02 systemd: Starting Session 3776 of user chris Aug 24 10:35:31 login02 sshd[12844]: pam_unix(sshd:session): session opened for user chris by (uid=0) Aug 24 10:35:31 login02 /usr/bin/x2golistsessions[12942] x2golistsessions has been called with no option Aug 24 10:35:32 login02 /usr/bin/x2gostartagent: x2gostartagent called with options: 800x600 adsl 16m-jpeg-9 unix-kde-depth_32 us auto 1 R xterm both Aug 24 10:35:32 login02 /usr/bin/x2gostartagent: client announced itself as ,,<my IP>' Aug 24 10:35:32 login02 /usr/bin/x2gosessionlimit[13005] x2gosessionlimit has been called Aug 24 10:35:32 login02 /usr/bin/x2golistsessions[13008] x2golistsessions has been called with options: --all-servers Aug 24 10:35:32 login02 /usr/lib64/x2go/x2gogetdisplays[ db_getdisplays called, server: login02; return value: Aug 24 10:35:32 login02 /usr/lib64/x2go/x2gogetports[130 db_getports called, server: login02; return value: Aug 24 10:35:33 login02 /usr/lib64/x2go/x2gogetdisplays[ db_getdisplays called, server: login02; return value: Aug 24 10:35:33 login02 /usr/lib64/x2go/x2gogetports[130 db_getports called, server: login02; return value: Aug 24 10:35:33 login02 /usr/lib64/x2go/x2gogetdisplays[ db_getdisplays called, server: login02; return value: Aug 24 10:35:33 login02 /usr/lib64/x2go/x2gogetports[131 db_getports called, server: login02; return value: <etc etc> So this is a CentOS7 system using SSSD for AD authentication, but using SSH keys Any ideas would be appreciated! Thanks, Chris
