cannot resume session in fullscreen mode

[sunweaver]

I noticed a peculariaty when playing with Arctica Greeter's Remote Logon feature.

With X2Go, at least, it is currently not possible to resume a session in fullscreen mode. This is, although the nxagent configuration (options file in X2Go) is fullscreen=1.

After some code reading, I am sure this needs to be addressed in nxagent itself, as the underlying framework (X2Go, client-side and server-side) does everything correctly IMHO.

In Screen.c in nxagentOpenScreen() there is a lot of if / then / else stuff going on that has an impact on the nxagentOption(Fullscreen) parameter.

This bug report is (a) for sharing the observation, (b) a request for feedback (have you seen this, too) and (c) a reminder for myself to work on this and get it fixed...

In Reconnect.c we set nxagentResizeDesktopAtStartup = False.

Bool nxagentReconnectSession(void)
{
  char *nxagentOldKeyboard = NULL;

  nxagentResizeDesktopAtStartup = False;

This will disable fullscreen if the display size of the connecting client does not match the fullscreen size used by the previous client's display.

But that is not what we might want, is it? I'll do some tests around this.

Hmm, if the user does not allow resizing we cannot provide a fullscreen session. I have shadow sessions in mind where you surely do not want to resize.

Can you please re-test with 3.5.99.18? I have tested that yesterday and it worked...

Confirm the same problem.

X2Go Server v4.1.0.0 on Ubuntu 18.04, X2Go Client v4.1.2.2 on Windows 10. NXAGENT - Version 3.5.99.16

When try to resume suspended sessions client's window blinks (appear for a moment) and hide eventually. To avoid this I have to stop/start new session on every disconnect. Later I realized that maximum available option instead of fullscreen works fine in session resuming. But this is not fullscreen and it's easy to mix x2go-client window (red highlight) with in-session windows (green highlight)

What's the version of nxagent on your server?

Please update to something current, we are at 3.5.99.26. See https://github.com/ArcticaProject/nx-libs#binary-builds where to get it.
