h1. Multihead\015\012\015\012{{>toc}}\015\012\015\012On multihead displays, [[subtle]] fetches information about screens preferrable via "XRandR":http://www.x.org/wiki/Projects/XRandR or via "Xinerama":http://en.wikipedia.org/wiki/Xinerama and shows _exactly_ one view per screen.\015\012\015\012h2.

Nvidia closed-source driver\015\012\015\012If you use Nvidia proprietary driver, you'll notice that subtle will simply not work if you try to use TwinView, in fact if you run xrandr, you'll see that the RandR extension detects one big screen instead of two screens\015\012\015\012The solution is to run [[subtle]] with the -n option (or --no-randr)\015\012\015\012<pre>\015\012subtle -n\015\012</pre>\015\012\015\012See #178 for more information\015\012\015\012h3. Nvidia dynamic dual-/singlehead\015\012\015\012Subtle will run fine, as long as your setup is statically and included in the xorg.conf. If you use a laptop you might be switching setups and need a more dynamical solution, especially as subtle and nvidia-settings dont work together nicely and changed made with the gtk-gui are not taking up by subtle. To avoid that you just need disper and some changes in the .xinitrc. I wrote a script that checks available displays with disper -l and then lets disper set it up correctly. The most important thing is running disper before subtle, so it takes up the changes.\015\012\015\012<pre>\015\012#!/bin/sh\015\012if [ $(disper -l | grep -c "Philips") == 1 ]\015\012 then disper -S && disper -e -d CRT-0,DFP-0\015\012fi\015\012\015\012exec subtle --no-randr --replace &>/home/alexander/subtle.log\015\012</pre> information
