Keyboard toggle
by Colin Kincaid Williams 22 Jan '13

22 Jan '13

I am wondering if there is a way to toggle between client and desktop keybindings using x2go. Is there a way to press a key to focus the keyboard between the client and the regular desktop environment? The reason I would like this feature is I use a keyboard heavy wm and I don't really want to change my keybindings just for remote sessions. It would be nice if I could use a key press or combination of presses to tell the computer to toggle between them. Does this make sense? Is this already a feature of x2go?

follow up: connection failed xhost: unable to open display (again)
by nigra truo 18 Jan '13

Hi, following up on the subject, I found out some more things: quote: I also noticed that it works for user Z, I can open a session. But currently never for user Y. It really does not work for this user and I don't understand why. I have enough space on the filesystem, I erased the .x2go directories in user Ys home folder. I can login over ssh with Y, so that is not a problem. This problem by the way started happening after a I had a power failure on my server, so I wonder if something got corrupted. I reinstalled (purged) x2goserver, so the x2go install should be fine. I now receive the xhost unable to open display on any system I try it with, with different OSes. When connecting from Windows 7 to user Z, I can establish a X2go session and when I use the Client app via gui, it fails to connect to user Y, BUT if I run it in the CLI, it works: *mm@myserver:~$ x2goclient-cli --user Y --server localhost Password: xhost: unable to open display "" xhost: unable to open display "" ln: creating symbolic link `/tmp/.x2go-Y/session-C-Y-52-1358533596.log': File exists xhost: unable to open display ""* So these xhost error messages are coming from the x2goserver and only for that one user (which is the strangest thing) So far I have not been able to enable debugging logging in x2goserver, editing the config file and restarting the server. The x2goserver does totally minimal logging and does not show what is wrong and why I cannot establish the connection. I have had lots and lots of trouble with xhost errors in the past, on any Linux box and the documentation that exists on it is totally shady and unconclusive. X seems to have a very weird idea of what security means and how it is instituted. (at where root is not allowed to access a users desktop without prior having given permission to it) There must be something special about user Y, something that x2go saved in the home dir. What directories would I have to clean up to erase all cache / config files that x2go might store there when an external client connects to it? Any pointers would be welcome. Thanks, Markus

x2go client on Mountain Lion
by Rodney Sparapani 17 Jan '13

17 Jan '13

Hi! I am using x2go and it is really wonderful! Keep up the good work. However, there are a couple of issues that I see which are very reproducible and I am hoping that someone has dealt them before. x2goclient 3.99.2.1 When you first make a connection, 2 error messages popup... The connection with the remote server was shut down. Please check the state of your network connection. and The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server. Clicking OK on both will allow you to proceed with login. After entering your username/password another error message pops up... Connection failed channel_open_session failed - Received SSH_MSG_DISCONNECT: 33554432:Received ieof for nonexistent channel 0. Clicking OK shows two sessions running, but no active window. So, I terminate those and start a new session. Then another error message pops up... sshd not started, you'll need sshd for printing and file sharing you can install sshd with <b>sudo apt-get install openssh- server</b> Clicking OK leads to another popup message... Connection failed Can not open file - Clicking OK brings up the session. This works very well and it is pretty much the same every time except for the occasional hang or crash. But, I am wondering... Is there a way to disregard the errors mechanically? By that, I mean it can be cumbersome to click OK so many times. Lots of times the windows are hidden and do not have the focus so you have to find them. Some times they are hiding right behind the main x2goclient window and I sit and wait for them to popup like an idiot. Or, can we just not have the error messages popup? I don't really understand what they are saying anyways. Besides, I am just clicking OK since there is no other choice. Any ideas?

Installing extra fonts
by "Stéphane Mutz (BLINKSIGHT)" 17 Jan '13

17 Jan '13

Hello, I'm facing a problem with a CAD application we are using. The application fonts are unreadable (too small and text is overwiriting itself). This application seems to use the primitive X mechanism for fonts. When used with an X2go client on Linux, everything is fine. xlsfonts also reports a large choice of fonts. But when used with an X2go windows client, the problem appears and xlsfonts reports only a handful of fonts available. After reading some NX articles, my understanding is that only the fonts available both on the client (Windows) and server side are reported. Is there a way to install extra fonts for the local (client) X server on windows? Regards, Stéphane.

connection failed xhost: unable to open display (again)
by nigra truo 17 Jan '13

17 Jan '13

Hi, I have had a few mails months back for this issue. It was from a Windows 7 machine to a Debian Squeeze X2goserver. After a long time of no problems, the problem is back. I could narrow it down a little though: The problem seems to be on the x2goserver, as I get the same error message even when connecting from a Linux system, EVEN if I connect on the x2goserver as another user. I also noticed that it works for user Z, I can open a session. But currently never for user Y. What can be wrong with user Y that it does not work for that one? Also, is there more logging in x2go? I find absolutely nothing on the server (does the x2goserver do any logging at all?) and the client just says connecting, waits for some time and then fails with this error message. I totally depend on this system to work, as I log into it on a daily basis to work and currently am stuck (x2go usually works very solid, that is why I come to depend on it so much). I would be grateful for any pointers to get this working again. Markus

Re: [X2Go-User] Installing extra fonts

Hi, Please include the list when replying, you probably need to use the "reply to all" (our similar) in your email client.

I Couldn't get X2Go client to start it's X server after that. I had to un-install the client and re-install and then recreate the profile. Is it possible that I need to totally log out of my x2go session on the server for a new DPI to work? I think that you need log out of the session yes. I haven't tried to reconnect to an existing session when changing the dpi. Why you needed to reinstall the client puzzles me, must have been a separate issue. > > That would be a nice way to increase the overall text size of the display. > > I'm running the 3.99 3.1 Windows client on Windows XP against an Ubuntu 12.10 server initiating a custom desktop with the "startlubuntu" command. > > I love X2Go !!!

Was that considered a bug?
by Rui Cruz 17 Jan '13

17 Jan '13

Hi there, Around 2 weeks ago we came across the release of 4.x and me and other user (sorry, can't remember his name) talk about problems on the Ubuntu desktop resolution matches the same one as the client. Was that considered a bug and is there an ETA for a fix? Thanks, -- Rui Cruz | Webmaster | 968271502 www.ruicruz.pt

Keyboard issues
by "Stéphane Mutz (BLINKSIGHT)" 16 Jan '13

16 Jan '13

Hello, I'm facing a couple of key mapping issues with X2go. My setup is the following: Server: X2go running on Ubuntu 12.10 server Session: XFCE4 Client: either Windows 7 or Linux 1) The status of Numlock is often lost when reconnecting to a session. It is always lost when connecting initially. It requires using numlockx almost at each reconnection. Is there a way to ensure a continuous sync of numlock between client and server? As a fallback, I'd be happy if numlock is always set on. 2) When switching between a Linus and Windows client, key mapping gets corrupted (e.g. the DOWN arrow key now behaves as ENTER). Is there a way to avoid that? Regards, Stéphane.

Which desktop for Ubuntu 12.04
by Christoph Mathys 16 Jan '13

16 Jan '13

This was meant to go to the list. Shouldn't the reply-to point to the list instead of the OP? We recently switched from Unity-2d to LXDE, server is ubuntu 12.04 and client Windows 7. We only use a very limited set of x2gos features. I have only noticed that on session start up, the LXDEs task bar is not completely visible until I resize the x2go window once.
