--- Comment #4 from Edwin Smulders edwin.smulders@gmail.com 2008-05-28 06:21:58 --- I have my monitors configured with twinview.
xrandr: dutchy@vampire:~$ xrandr Screen 0: minimum 3360 x 1050, current 3360 x 1050, maximum 3360 x 1050 default connected 3360x1050+0+0 0mm x 0mm 3360x1050 50.0*
This is my Ubuntu installation, I have xinerama working on my Gentoo installation but there my wine doesn't work yet. As soon as my wine works there I can test xinerama.
