So, it appears that on initial connection, even on resume, the display is set to 800x600 and then resized to what is in the session preferences. With the change to 800x600, KDE tries to re-arrange the windows to fit better it seems. Why is this done instead of either setting the size to the session preferences or preferably the size of the existing session? -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane or...@nwra.com Boulder, CO 80301 https://www.nwra.com/ smime.p7s Description: S/MIME Cryptographic Signature ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
[X2Go-User] Complaints about windows resizing/moved on session resume
Many of our users are complaining about: something in the EL8/X2Go/KDE? interface now just runs roughshod over the windows you have open, between suspending and resuming sessions. Windows are re-sided, moved, opened, closed...at random. I often have multiple windows open and, for example, running IDL or editing or something, and I have them placed where I want as I am testing and debugging or writing code, I suspend / restore the session and come back to just randomly placed, sized, opened or closed desktop. **i don't like people mucking with my desktop** whether real or virtual!!! The three of us mentioned to each other that we feel like we are continually re-sizing, finding, and just spending time counteracting what has been done to our setups. So, what's going on what what can be done to stop it? Clients and server are EL8. Desktop environment is KDE. We have a mix of x2goagent and x2gokdrive sessions. We've removed kscreen. Any help would be greatly appreciated. Thanks. -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane or...@nwra.com Boulder, CO 80301 https://www.nwra.com/ smime.p7s Description: S/MIME Cryptographic Signature ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Even after removing kscreen, one user is still having issues: The effect seems to be a bit cumulative. First time or two after restarting x2go, no resizing.

Hi Stefan,
Thank you very much for your response! Yes, it looks like our SSH server

X2Go clients.
The kind of response that looks like this:

Enter a passcode or select one of the following options:
Passcode:
We are running an HPC machine here, with user authentication coming from a
National-wide HPC organization, that chose Duo for MFA. We cannot easily just
pick a random 2nd factor vendor.
The related common SSH/SFTP/SCP GUI clients like PuTTY and and MobaXterm and
FileZilla do not seem to have this issue, at least in recent versions. (I just
had a user that out of exasperation tried to run X2go over an SSH client
created by Putty which is of course impossible) .
I think the main difference between x2goclient and at least putty is
that x2goclient is managing the ssh interaction and feeding the prompts
as needed. putty is simply presenting the prompts to the user and
allowing them to interact with them. I'm not sure x2goclient has any
other way to know that the connection is waiting for more authentication
input.
x2go client has the following known prompts:

The reason that I'm interested in it is because there is a bug in XQuartz when running on Apple silicon that results in a black screen: https://github.com/XQuartz/XQuartz/issues/31 this has made X2Go unusable for one of our users - so a non-X based client is very attractive at the moment.

Also, is there any plans to add a second password field to the clients al la Cisco AnyConnect etc? We use YubiKey smart cards for our MFA. Load the pkcs11 module into ssh-agent and only accept ssh keys from the smart cards on the remote side. We use IPA with AD trust and users in AD to handle the certificates.

I'm having a lot of trouble getting a gstreamer based video player to work under X2Go. First off it looks like Xv is not supported. Is that something that ever will be? Next thing I'm seeing with the parole player is that the video frame goes black when I pause it. I'm also trying to use the fluendo gstreamer codecs and seeing segfaults (apparently in the fluendo code) when using dragon player to watch videos.

It was pushed to stable 2 months ago. Please try

Hello,
I have been using x2go for a couple of months now and have been very
happy with it. My configuration is a server running a virtual
machine (CentOS) on it and x2go server running on that virtual
machine.
I connect to it through the x2go client on Windows 10.
One of the features that I love about x2go is its support for
multiple
displays on the client side through xinerama. I have 2 monitors
and x2go
treats the session as such. The session will open across both
monitors
and I can easily maximize windows on each of these monitors.
Well, that was until the latest reboot of the server. Now, even
though I
have the xinerama option on, the x2go client treats my 2 monitors as
one: even though the session opens across both monitors, when I
maximize
a window, it will be maximized across both monitors.
I have tried to reset the client, the server, play with different
options, but so far to no avail.
Any ideas on how I could get the 2 monitor behavior back?
What version of nx-libs and the OS on the server? There have been
issues with Xinerama support in the Fedora/EPEL nx-libs packages
recently. See https://bodhi.fedoraproject.org/updates/?packages=nx-libs

Any idea how to fix that? I don't quite follow what you mean by "globally". Are you using desktop-sharing and connecting to an existing X session and want to use that ssh-agent? I need one ssh-agent per X session that all child processes can access. In that case perhaps your x2go ssh connection is forwarding the ssh-agent connection from the client machine and you need to disable the agent forwarding. Probably you are right. But how to disable it in QT4 x2goclient? If I add Host * ForwardAgent no to ~/.ssh/config it affects a separate ssh session but not x2goclient's one. And I failed to find any command line/GUI x2goclient option that is related to ssh agent forwarding. Hmm, it appears that the code never calls ssh_options_parse_config(), whether by intention or not I do not know. CCing the dev list to get their take on it. But the libssh docs indicate that it should be called: http://api.libssh.org/master/group__libssh__session.html#ga7a801b85800baa3f4e16f5b47db0a73d And I can confirm that x2goclient does appear to forward the SSH_AGENT at least if using the ssh-agent for authentication to the remote server. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA DivisionFAX: 303-415-9702 3380 Mitchell Lane or...@cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com ___ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user
Re: [X2Go-User] x2go and xinerama
On 12/02/2015 08:34 PM, Dimitri Loizos wrote: Hello, I have been using x2go for a couple of months now and have been very happy with it. My configuration is a server running a virtual machine (CentOS) on it and x2go server running on that virtual machine. I connect to it through the x2go client on Windows 10. One of the features that I love about x2go is its support for multiple displays on the client side through xinerama. I have 2 monitors and x2go treats the session as such. The session will open across both monitors and I can easily maximize windows on each of these monitors. Well, that was until the latest reboot of the server. Now, even though I have the xinerama option on, the x2go client treats my 2 monitors as one: even though the session opens across both monitors, when I maximize a window, it will be maximized across both monitors. I have tried to reset the client, the server, play with different options, but so far to no avail. Any ideas on how I could get the 2 monitor behavior back? What version of nx-libs and the OS on the server? There have been issues with Xinerama support in the Fedora/EPEL nx-libs packages recently.

Hello,
I'm sharing a Java application over x2go which is started as single
application. Now there is a problem to access the shared folder of the
client.
x2gomountdirs mounts the folder as a link to /tmp/.x2go-{$USER}/... When
the java applications file chooser dialog wants to access /media then
the selection jumps to /tmp but cannot find the hidden folder
/tmp/.x2go-{$USER} directory, because it is a hidden .dot directory.
Is ist possible to change the hardcoded directories to another, not
hidden path, eg. /tmp/x2go-{$USER}... and additionally move the
temporary files to the users home directory?
If x2go needs to manipulate any files as root (I do not know), then this
needs to not be in the home directory which could be on NFS. I agree
though that it shouldn't be hidden, and also suggest that it should be
in XDG_RUNTIME_DIR.
