Re: 302.17, XRandR multimonitor doesn't work
So I tried some different window managers. I don't have many wm at hand, for what I've tried:
i3, wmii: affected; awesome: only work when setting mode via nvidia-settings, if the mode is set via xrandr command line, same problem.
Even if the problem is in the wm, this indicates bad compatibility of nvidia driver, as those wm have no problem with intel graphic cards.
