Something like this should work for you, too: Section "Monitor" Identifier "Monitor-DP1" Option "AutoServerLayout" "on" Option "Rotate" "normal" EndSection Section "Monitor" Identifier "Monitor-VGA1" Option "AutoServerLayout" "on" Option "Rotate" "normal" EndSection Section "Device" Identifier "Intel0" Driver "intel" BusID "PCI:0:2:0" Screen 0 Option "AccelMethod" "sna" Option "Monitor-DP1" "DP1" Option "ZaphodHeads" "1:DP1" Option "TearFree" "on" EndSection Section "Device" Identifier "Intel1" Driver "intel" BusID "PCI:0:2:0" Screen 1 Option "AccelMethod" "sna" Option "Monitor-VGA1" "VGA1" Option "ZaphodHeads" "0:VGA1" Option "TearFree" "on" EndSection Section "Screen" Identifier "SCREEN" Option "AutoServerLayout" "on" Device "Intel0" Monitor "Monitor-DP1" SubSection "Display" Modes "1024x768" Depth 24 EndSubSection EndSection Section "Screen" Identifier "SCREEN1" Option "AutoServerLayout" "on" Device "Intel1" Monitor "Monitor-VGA1" SubSection "Display" Modes "1024x768" Depth 24 EndSubSection EndSection Section "ServerLayout" Identifier "LAYOUT" Option "AutoServerLayout" "on" Screen 0 "SCREEN" Screen 1 "SCREEN1" RightOf "SCREEN" EndSection Now, the ZaphodHeads setting is something you need to set up for your own machine, since vendors can wire up video outputs differently. Look for messages like this in /var/log/Xorg.0.log: [ 42699.692] (II) intel(0): switch to mode 1024x768@60.0 on DP1 using pipe 0, position (0, 0), rotation normal, reflection none There will be one such line for every connected video output but autodetected when there's no explicit configuration. You need to specify the pipe number along with the output name in Option "ZaphodHeads" for every Device section in the config. Also, BusID should match your machine, not the above quoted example. Another thing is that with using the Intel driver, the outputs are called DPI1, VGA1 and so on, with the output type and number written as you see. With the modesetting driver, they become DPI-1, VGA-1.
