No, but closed-source/commercial/proprietary.

In theory, yes. But somehow the shift and space bar being pressed and
released first tell it to "keep" the keypresses to itself, rather than
sending them and the function key on to the X Server.

I'll keep that in mind.

They offer a time-limited trial version [0], but IIRC, you still need to
register somewhere with your E-Mail address (and they'll send you promo
E-Mails during the trial phase, and possibly even afterwards).

As I said, feel free to do so - you're way more knowledgeable about the
code involved than I am.

I agree on that, I'd just like to know if we have a bug with the window
decorations as well. ;-)

Just to be sure (and to document it in the bug): what version of 
nx-libs are you seeing this with?

I don't remember exactly about windows decorations, I'll try again but in any 
way, the result is just plain unusable so in this specific situation (aka. 
resuming a Published Apps session from a TCE), it would be better to block the 
resume and propose to close the session before opening a new one.

Wait a minute - we are running a Display Manager in X2Go-TCE ... in the 
live edition at least. 
So Window decorations should be there, just no task bar. 

Walid - did you change anything in your TCE setup compared to 
X2Go-TCE-Live, branch "feature/openbox"? 

What SHOULD happen is that X2GoClient starts up in fullscreen, but any 
popup it shows (like asking for a keyfile's password, or displaying that 
there's no route to host) should have window decorations. And I'd assume 
that the same window manager would put window decorations around PubApp 
windows once the session resumes. 

(Of course, it will still be almost unusable, as there's no task bar, no 
logoff button, and no menu, but I'm surprised to hear that there are no 
window decorations.)

leaving you with ctrl-alt

So I guess that the application is consuming that very keypress
somehow by communicating with the X server (grab the key(s) in
question).

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.

[X2Go-Dev] Bug#1220: Modifier Keys not working as expected

2017-09-26 Thread Stefan Baur 
package: x2goclient

(devs: feel free to reassign this to nx-libs/arctica, if the cause is
not in X2GoClient)

A certain application requires the following keypresses:

- 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
- 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.

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.

[X2Go-Dev] Bug#740: Ship a default, small-footprint, F/LOSS PDF viewer with x2goclient

2017-09-26 Thread Stefan Baur 
Alex and I had a look at this bug while @ X2Go: The Gathering 2017.

We currently have a drop-down list of printers to choose from, and the
option to specify a custom print command instead (using a checkbox and a
text field).

The idea would be:
- SumatraPDF becomes the new default PDF viewer for X2GoClient for
  Windows and gets bundled with it, just like VcXsrv.
- You will be able to de-select it during X2GoClient installation, if
  you prefer using your own PDF viewer and want to save a few megabytes
  of storage.
- There will be the following options using SumatraPDF "behind the
  scenes" in the print dialog:
  - An option to always print to the system default printer
  - The current "choose a printer" dialog, which will set a default for
X2GoClient only
  - An option to always prompt the user to select a printer when a print
job is being sent.
- The option to specify a custom print command in the print dialog will
  remain. It will default to a SumatraPDF call with sample parameters on
  Windows systems.
- The option to specify a viewer command for PDFs in the "Show as PDF"
  dialog will remain, and will default to SumatraPDF on Windows systems.

This feature request ist currently awaiting funding.
It is expected to take no longer than 8 hours to implement, once funded.
