[X2Go-User] Is it possible to get pulseaudio sound in app mode?

2014-10-07 Thread Edouard Gaulué 

Hi community,

I'm trying to achieve this: build a Firefox/Iceweasel application server 
(Debian Wheezy) with several simultaneous clients using Raspberry Pi 
(Raspbian) using x2go, everything being in a LAN. Of course each user 
needs to hears just its own application sound. I don't want to send a 
full desktop manager as I just want them to use Firefox/Iceweasel.


As of now, I don't have too much trouble to start Firefox/Iceweasel from 
clients. Only troubles I get are :
 * the size of the Firefox window doesn't manage to get the local 
screensize despite I tick Fullscreen in x2go, so I must use --heigth 
and --width command line parameter

 * menu at the top doesn't work ether
 * no sound at all

I think everything is linked with the fact I try not to use a windows 
manager, but I'm even not sure pulseaudio can deal with several 
simultenous users.


Any advices/ideas would be really appreciated.

Best regards, EG

All I can add is that in general, pulseaudio sound between a Windows
client and an x86-based Debian Wheezy works fine, even with published
applications and multiple users.  So it is most likely an issue with
your particular setup.

Maybe I'm misinterpreting your statement, but if you don't want to run
a window manager on the server side, you should be running one
locally, and you have to take care of starting pulseaudio on the
client as well.

You could do any of the following, IMO:
- - Run a remote desktop environment and set the rights on the *.desktop
files in a way that the users you want to let in via X2Go can only
access Firefox and the Logoff menu item.
- - Run a local desktop environment/window manager, possibly with some
manual configuration for pulseaudio.
- - run https://github.com/alandmoore/KiLauncher on the server and
specify the allowed apps there.

Note that as long as users can define their own sessions, there's
nothing that stops them from specifying another application unless you
removed access rights on the particular executable on the server.  So
don't think of published applications as a security feature, they are not.
