Re: [X2Go-User] Upgrading to nx-libs 3.5.99.1
by Mike DePaulo 03 Oct '16

03 Oct '16

Hi Robert, 1. I updated the email subject to make it more clear. 2. For those who do not know, this is a reply to Robert's nx-libs 3.5.99.1 upgrade issue as listed in: http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1089 3. Software installer is the wrong tool for the job. "dpkg -i" does not work with apt repos. It also doesn't handle dependency resolution. 4. To add this apt repo on Ubuntu 16.04, you would create a file with a name like this: /etc/apt/sources.list.d/nx-libs-beta.list ("nx-libs-beta" can differ. The folder path and the ".list" extension must be the same.) with these contents: deb http://packages.arctica-project.org/ubuntu xenial main You also run this command: wget -qO - http://packages.arctica-project.org/archive.key | sudo apt-key add - 5. To recover your system, I recommend the following: a. Run `apt-get update` b. Run `apt-cache search libnx` c. Uninstall all the libnx packages, such as by running: sudo apt-get purge <package-list> Note that this step (or the next one) will result in x2goclient and x2goserver being uninstalled. That should be OK, see step f. d. Also remove "nxproxy" if it is still installed. e. Add the nx-libs 3.5.99.1 repo from #4. f. Install x2goclient or x2goserver (+ any other client/server packages.) This should pull in nx-libs 3.5.99.1. 6. For those who are wondering why this upgrade issue can occur when using "dpkg -i" on all the nx-libs deb packages, it is because nx-libs 3.6 drops many of the X11 libraries that were part of nx-libs 3.5 in favor of the system's X11 libraries. Thus those library packages no longer exist, and the entire upgrade process needs to involve removing those libraries. -Mike On Sun, Sep 18, 2016 at 10:12 PM, Robert Dinse <nanook(a)eskimo.com> wrote: > > I used dpkg -i file, same as the software installer.

Hello, I have my server on Argentina with about 20+ users. Now just trying to login from Moscow, latency is about 288ms. While speeds shows a 70/70Mbps upload/download testing with a server not far from here, against other in my country is much more than a 1Mbps. x2goclient refuses to connect "no data received from proxy".

X2goclient DPI setting
by Michael Eager 28 Sep '16

28 Sep '16

Hi -- What does the "Set display DPI" session preferences do? I have a new 4K high-dpi display (161 dpi) and I'm connecting to a remote X2go session. The window to the remote is small and any window I open in the remote has fonts scaled to 96 dpi, which makes them hard to read. In the remote session, I can set Xrdb:dpi in .Xdefaults and this helps with the font scaling issue. -- Michael Eager eager(a)eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077

Problem running audio applications in TCE mode
by Walid MOGHRABI 23 Sep '16

23 Sep '16

Hi, I'm still struggling to make my TCE setup work correctly. I managed to fix about every bits here and there but there is still one important part that I can't get to fix which is managing audio applications to work in TCE mode. To be clear, what I call "TCE mode" is pxe booting an diskless station with x2gothinclient (per the doc setup with default settings, Debian wheezy based with heuler x2go client) When I open a X2Go session with a local x2go client on my Ubuntu laptop (or even with x2goclient under windows), no problem, I have sound with PulseAudio fully working, I can play videos on youtube, hear MP3s with totem or any other audio application. Running the same session with a TCE client works great until I want to hear a sound ... youtube videos are hanging with no sound, playing MP3s don't even start. Anything related to PulseAudio seems broken in TCE mode and this is very annoying to me because we'd like to deploy TCEs in my company to replace about 150 Windows PCs but this is for a call center so if audio is not working, this is a no go. I'm pretty sure this can be fixed with some PulseAudio configuration tuning but I must admit that I'm totally confused by PA and I don't understand a bit of the beast so any help would be gladly welcomed !

Are there RPM repositories for nightly builds and the artica-project where I can get the necessary fixes for Fedora 24 similar to those for Ubuntu 16.04?

Fedora 24
by Robert Dinse 17 Sep '16

17 Sep '16

Puzzling stuff with Fedora 24 and x2go, it has the same issue as Ubuntu 16.04 with respect to xrandr being 1.2 and needing 1.3 (command line version is 1.5), yet it somehow manages to update the screen size anyway. Another problem, no /var/run/utmp entry made with x2go logins, not even if you open up a terminal. It allows me or other users to be completely invisible without examining processes. Both who and w return nothing. I am using Mate desktop with lightdm desktop manager. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

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".

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

by Jordan Sokolic 27 Aug '16

Hello, I use a web frontend for work that runs locally on my server over X2Go for about one year with success. Some months ago I noticed a significant decrease in performance when using Firefox. My server is running Ubuntu 16.04 with MATE desktop, Windows 10 client. Up to Firefox version 39.0.3 performance of loading pages, scrolling, browsing etc. was nearly flawless over a 5Mbit WAN link (with the exception of embedded video elements). However it seems the release of Firefox version 40.0 introduced some changes in rendering (see https://www.mozilla.org/en-US/firefox/40.0/releasenotes/) that do not play nice with X2Go. Further reduction in performance was noticed in versions 46.0 and 48.0. The current release (48.0) even has trouble rendering a plain text document without lag and choppiness. I have tried toggling various flags relating to graphics, compositing, rendering, etc. to no avail. To work around this problem the only solution I have found is to forward ports over a separate SSH tunnel and browse locally, but this is cumbersome to set up every time I need to connect. I have preferred Firefox to Chrome over X2Go because the latter has always been unusably slow; now they are both similarly choppy and slow. Has anyone else noticed this? Any advice or help would be appreciated. Regards Jordan

Hi Robert, switching to x2go-user context as being OT on x2go-project. On Do 25 Aug 2016 06:48:53 CEST, Robert Dinse wrote: > Can't figure out where mate has start up scripts.

In that directory, you can find some tweaks for default applications and such (debian-mate-default-settings or ubuntu-mate-default-settings by package name). For autostarting applications, MATE strictly follow the XDG specs by freedesktop.org.

I see that there have been updates over the past year but its been a while (2+ yrs) since I last implemented & tried it. Also, keep waiting to hear more about mTeleplayer development. Anyone have any recent experience with the x2go browser plugin or info on mTeleplayer state? http://wiki.x2go.org/doku.php/wiki:advanced:x2goplugin thanks Brian
