Hi folks,
Another question for you: sometimes I reconnect to an x2go session from a computer that has a smaller display than the one that I previous connected from. The problem is that some of the windows now fall partially or fully off the display. The partial ones are usually accessible by clicking and dragging their borders until enough of them appears so that the window can be dragged back in to full view. The usual X11 keystroke/mouse combination for dragging a window isn't passed through to the x2go session, so this only works on the high-level x2go window (presumably there is a way of creating a different keystroke/mouse combination that is passed through).
But for windows that fall completely off the screen, I can't see how to access them. Any ideas?
I'm using xfce.
Regards, Michael
Press ctrl-alt-f twice (switch to fullscreen and back again), this should rearrange the windows. However, the same should also happen on reconnect so I am wondering how that situation you describe can occur... Can you please post a session log of such a reconnect?
Thx,
Uli

Hi Uli,
Thanks for this suggestion.
It turns out the session log I posted earlier (with the nxagentReconnectFailedFonts message) was the one immediately before the "disconnection after one second" problem I reported in the other thread. This earlier session resized the screen down from its original 3768x2123 dimensions. And in fact, this session *did* work, i.e., the font problem didn't cause the session to disconnect after one second. However, some of the windows did appear off the screen.
The immediately following entry in session.log is the one that had the one-second disconnect problem. This was an attempt to connect from a different computer (but one which I had been using successfully prior to the earlier entry).
To try to clear up the confusion, here is the chronological sequence of events:
(1) Successfully running at 3768x2123 screen size using computer A.
(2) Reconnect using computer B; nxagentReconnectFailedFonts occurs, but session OK; now running at lower screen size (1853x1145?), which causes windows to be at the edge, or beyond. The session log is the one posted in the other thread.
(3) Attempted to reconnect with computer A; nxagentReconnectFailedFonts occurs, and session disconnects after about 1 second. The session.log entry is in-line below;

This should not happen. NX has xrandr and xinerama included. So in that case your desktop environment/window manager is informed about size changes of the underlying X server (which is nxagent) and reorganize the desktop accordingly. It seems to me that your xfce ist not doing this for unknown reasons. Can you please run
- xrandr
- xpdyinfo -ext XINERAMA (last few lines are enough)
inside the session when that happens?
In the log file I cannot see the resize event. Hmm. Have you tried if temporary switching to fullscreen and back helps?
Before diving deeper into that problem please update to 3.5.99.26 and try to provoke that situation there.

I notice the additional nxagentSighupHandler line.
For reconnect the nxagent has to be woken up by sending a SIGHUP to the process. If there are multiple signals the above message appears. This is because of the NX_CLIENT setting I mentioned before which sends another SIGHUP when trying to show a dialog with wrong script in place. Fix the NX_CLIENT stuff and you'll be fine.

Hi Uli,
Thanks again for your quick and very helpful responses (I didn't realize that x2go came with free 24/7 support!). I will try your suggestions, and post again if I have any new information. The session log I sent earlier didn't include any manual attempts at resizing the screen.
Regards, Michael
