[winswitch] fakeXinerama questions

[Lukas Haase]

Hi,

I have some questions regarding fakeXinerama. I use it in the following setup:

1.) Client is a Win 10 laptop with 3 monitors attached:
1366x768      1920x1200        1920x1080

2.) Ubuntu LTS Xenial Xerus with xpra running xpra.
On the xpra server, I do not start the X client directly but use DISPLAY=:100 ssh -X otherserver

3.) otherserver is a RHEL5 linux system that runs proprietory software

Stated differently, I use xpra as a terminal server.
Now if I want to use fakeXinerama, would I use it on the xpra server (preload it into ssh) or on the RHEL5 server (preload it into the proprietory applications) or would it not work at all?


My second question is regarding fakeXInerama in general. I still do not 100% understand what it really does.
Which advantage does it give to me in the setup above?

Ultimately what I could love is to let xpra IGNORE the first monitor (1366x768) and make it ONLY use the second two (1920x1200, 1920x1080). I tried creating .100-fakexinerama with the following content (on the xpra server and starting xterm rather than "ssh -X"):


# 2 monitors:
2
# DISPLAY1
0 0 1920 1200
# DISPLAY2
1920 0 1920 1080

However, I do not see any differences.

Does this even do what I want and if yes, what is the correct format?

Thanks!
Lukas
