Web browser performance over X2Go
by Jordan Sokolic 27 Aug '16

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.

How updated is the x2go browser plugin capability?
by brian mullan 26 Aug '16

26 Aug '16

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

why can't you specify the target server using x2goclient from the CLI
by brian mullan 25 Aug '16

25 Aug '16

*pyhoca-cli* has the *--server* option to specify the IP of the target desktop server but using *x2goclient* from the CLI apparently *does not* provide that option ? is there a reason it doesn't or couldn't ? thanks Brian

x2go plasma 5 support
by Samuel Bernardo 24 Aug '16

24 Aug '16

I'm using plasma 5 with x2go for remote sessions, knowing the glx 1.3 limitation for running plasmashell. I can use x2go for remote session with plasma 5, besides the crashes that happens with kdeinit after login and with plasmashell when trying logout. For solving the logout crash I terminate x2go session and remotely kill all the applications that haven't finished. Besides this login and logout problems, every other applications I use seems to work as expected. Since this is a bit annoying I ask the developers if it is expected x2go to support kde5? Thanks

'stty -tostop' in shell config file prevents X2Go connection
by René Genz 20 Aug '16

20 Aug '16

Hi, is the following a bug or expected behavior? stty -tostop is in user shell configuration file on remote machine. Local log on to remote machine is no problem. X2Go connection to remote machine cannot be established with error message: Error --- Connection failed. stty: 'standard input': Inappropriate ioctl for device stty: 'standard input': Inappropriate ioctl for device [OK] Removing the line was the only way to solve the issue. I tested with: - Bash and TCSH ${HOME}/.bashrc ${HOME}/.cshrc - X2Go server: x2goserver-4.0.1.19-11.fc24.x86_64 Fedora 24 x86_64 - X2Go client: x2goclient-4.0.5.1-1.fc24.x86_64 on Fedora 24 x86_64 and Mac OS X 10.10 -- Kind regards, René

Ubuntu 16.04.1
by Robert Dinse 08 Aug '16

08 Aug '16

There is definitely a bug in x2go operating under Ubuntu 16.04.1. I upgraded a machine that was running Ubuntu 15.10. I have my x2go client configured to use display 1. Under 15.10, when I connected it did use my entire screen but I could still switch work spaces using control+alt+arrows as desired. After this same machine was upgraded to 16.04.1 LTS, when I connect it uses my whole screen locally but creates a window in it that is 600x800 or thereabouts of the remote machine instead of using the entire display. I changed nothing else when I did this upgrade. It worked properly prior to "do-release-upgrade" and not after. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Problems with shared folders
by dura-zell＠dynamik.ddns.net 07 Aug '16

07 Aug '16

Hi all I have installed x2go and so far it is working fine except two things: - automounting of shared folders - (auto)-mounting of client-local media After reading, searching and trying for some days now, I'm stuck and need help. Some details about the involved machines: Server: Xubuntu 16.04.1 on an ESXi (4GB RAM, 4vCPU, 30GB Disk) Clients: - HP t5540 thin client with lubuntu 16.04.1 on it - an older kubuntu (14 something) on a normal PC On all machines the current (stable) x2go version from the ppa is installed. In the session-settings, I configured a shared folder "media". I installed x2gousbmount to be able to mount an usb key on clientside. The users on the server are in the "fuse" group. After connecting to the session I can't find my local shared folder. I'm getting this in the servers log file (loglevel debug): (terminaluser = the user on my server, localuser = the user on the client) Aug 7 20:50:37 ts1 systemd[1]: Started Session 120 of user terminaluser.

X2Go Server and Ubuntu 16.04.1
by Robert Dinse 01 Aug '16

01 Aug '16

I've got x2go on a number of Ubuntu 15.10 servers and no problem with them. I recently installed a new server with Ubuntu 16.04.1 LTS and there is a nasty problem with it. On the client side, I select Display 1, on the 15.10 servers this fives me a full screen like the Full Screen selection except I can switch between workspaces on my local machine with control+alt+arrows. On 16.04.1 LTS instead of getting a full screen, it gives me a full black screen with a 600x800 window in the upper left into the 16.04.1 server. I know 16.04.1 made some changes to Xorg. I am using Mate for the desktop on both systems but on 15.10 I installed the Mate spin of Ubuntu, however, with 16.04 I used the Server install and then installed Mate after the fact. If I try to use System->Preferences->Hardware->Display it tells me that xrandr version is too old, says I need 1.3 and it is 1.2, however, xrandr says program version is 1.5 but server reports 1.2, where as in 15.10 this works properly. Any hints on how to fix this? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
