Trying to get x2go working properly from NoMachine
by Bragg, Richard 16 Sep '16

16 Sep '16

Hi All I am trying to get x2go working on a virtual (headless) OpenSuse 13.2 KDE server. I have used NoMachine in the past on a hardware Workstation with no issues. It starts the session and reconnects fine when the line drops. On the new server though the graphics are slow and on reconnect the colours on some applications are incorrect, (Eclipse - white on white isn't readable). I've pulled the latest x2go client for the Windows laptop and installed x2go via Yast. Now to side track a little. I mostly use this virtual desktop from my laptop which can have 3 possible monitor situations. 1)On own - smallish widescreen 2)With internal screen and single external monitor at 1280x1024 (external is Display 2) 3)With 2 external monitors - Display 1 is the 1280x1024 I want to use Sometimes I will pull laptop from docking station effectively switching to 1) above. Then put back and need the display to be handled appropriately. NoMachine player does very well. It seems to remember where I put the display and sends to the correct monitor, even on resume. Issues Using x2go client the fonts are too big. Nomachine and PyHoca-GUI get it right. Xlsfont on NoMachine and PyHoca show thousands of entries, x2go client has around 700. I installed the fonts with the application. X2go client crashes on resume. I create session OK, full screen on the 1280x1200 monitor. On resume it tries to open a smallish window and then the xserver crashes. The PyHoca does work as intended if I use "Maximise" but then the "window" takes over the monitor and I can't easily switch to other apps on that screen and back again. CTRL-ALT-M will let me access other apps but then it's hard to switch back. PyHoca full screen tries to use both screens on laptop - not what I want. Sometimes I can't resume. I get errors about nxproxy or no permission to display in error log. Then I usually have to go to server and manually remove old session files and try to get a new session. This hasn't been an issue so far but could be if I got disconnected while editing. I really hope to get x2go to work as it seems far quicker than NoMachine in this circumstance. But I do need it to be stable and reliable. Nomachine server 3 (last one with virtual desktops) has worked great. I can resume sessions in different resolutions and on different client machines and all my programmes are there, including remote apps throwing screens back to the "workstation".

Well whatever was broken the first time I tried it, I went back after fixing other things today, and tried it again, now it is working fine. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Updating from X2Go's Debian repository fails due to GPG error NO_PUBKEY F4A7678C9C6B0B2B
by Holger Krause 14 Sep '16

14 Sep '16

Dear list, since last night running 'aptitude update' gives an error on a machine with X2Go's Debian repository added: W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://packages.x2go.org jessie InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F4A7678C9C6B0B2B According to http://wiki.x2go.org/doku.php/wiki:repositories:debian I would expect the file to be signed with key E1F958385BFE2B6E. Has the key to sign the repository been changed by the project? Looking forward to receiving any feedback! Best, Holger

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

Re: [X2Go-User] Web browser performance over X2Go

Hi Jordan, Firefox 47 disabled XRender support by default. Go to about:settings and search for xrender, set the property to true. That made it a lot better for me.

Hi, Unfortunately setting MOZ_DISABLE_IMAGE_OPTIMIZE=1 did not make a difference. Thanks though.
