Comment 42 for bug 363375

Hi Pete,

No it works just like a four screen Xinerama setup should. The two twinview pairs are tied together with Xinerama the X config:

    Option "Xinerama" "1"
    Screen 0 "Screen0" 0 0
    Screen 1 "Screen1" RightOf "Screen0"

The fake Xinerama installation then allows the dimensions and layout of the physical screens to be defined for the benefit of window managers and apps.

The fake Xinerama config file for four 1280x1024 monitors in a row:

4
0 0 1280 1024
1280 0 1280 1024
2560 0 1280 1024
3840 0 1280 1024

It is working well for me. And firefox doesn't crash all time now.
