Hi Brian, Did you have to use the xrandr in your .xinitrc as well along with this, or are you saying that you have dual head working without the xrandr?I was a little surprised when I saw that you have it working like this because man xorg.conf states the following: " Screen number This option is mandatory for cards where a single PCI entity can drive more than one display (i.e., multiple CRTCs sharing a sin- gle graphics accelerator and video memory). One Device section is required for each head, and this parameter determines which head each of the Device sections applies to. The legal values of number range from 0 to one less than the total number of heads per entity. Most drivers require that the primary screen (0) be present. " I am going to try your configuration tomorrow however as it seems a little cleaner. One additional thing that I have noticed is that your config doesn't mention the "virtual" option on the display subsections. When I have run xrandr it complains with the following error: xrandr: screen cannot be larger than 1920x1080 (desired size 3840x1080) Thanks Aaron
This setup does dual screens without the need for xrandr. You are correct -- when you try and do the setup with xrandr it does require the virtual option in your xorg.conf. This setup does not.
Just run startx or xdm and you have dual screens. --Bryan
