A certain application requires the following keypresses:
Is the spplication's name secret?
- Hold down ctrl, shift and alt
- while holding them down, press the space bar
- let go of shift and space bar, keep holding down ctrl and alt
leaving you with ctrl-alt
- with ctrl and alt pressed, press a function key (F1-F6)
- let go of all keys
This works when the application is run on :0 - the "ctrl-alt-Fx" is not passed down to X, so no switch to tty1-tty6 occurs, which is the intended and expected behavior.
So I guess that the application is consuming that very keypress somehow by communicating with the X server (grab the key(s) in question).
However, with the application running in an X2Go session, the same sequence of keys will trigger a switch to tty1-tty6 on the local client.
The application probably also communicates with the X server which this time is nxagent. So nxagent would probably not pass the grab to the real X server.
You could try if the coming autograb feature helps here.
But for analysis we'd need the application to see what is doing.
For the records: I think it is nx-libs so we should open an issue there. But I am not sure if we will be able to fix that at all.
