Hi,
I have a small Kabini base mini PC that has a primary DisplayPort-0
output and a secondary HDMI-0 output.
I would like to have a configuration where only the primary is used
no matter if there's a monitor attached to the secondary.
(Don't ask, business requirements.)
No matter how I try, the secondary monitor output is the clone
of the primary.
Is there a way to disable a specific Radeon output from xorg.conf?
Here's a configuration below that should work but doesn't.
The same method works for the Intel driver: explicitly reference
the to-be-disabled ZaphodHead in a Device section, a Screen section
in turn references this Device section and then leaving the second
Screen out of the ServerLayout section give the desired result,
X leaves the unwanted output in terminal mode.
Section "Monitor"
Identifier "HDMI-0"
Option "AutoServerLayout" "on"
EndSection
Section "Monitor"
Identifier "DisplayPort-0"
Option "AutoServerLayout" "on"
EndSection
Section "Device"
Identifier "RADEON"
Driver "radeon"
BusID "PCI:0:1:0"
Option "AutoServerLayout" "on"
Option "ZaphodHeads" "DisplayPort-0"
Option "Monitor-DisplayPort-0" "DisplayPort-0"
Option "TearFree" "on"
Option "DRI" "3"
EndSection

BusID "PCI:0:1:0"
Option "AutoServerLayout" "on"
Option "ZaphodHeads" "HDMI-0"
Option "Monitor-HDMI-0" "HDMI-0"
Option "TearFree" "on"
Option "DRI" "3"
EndSection
Section "Screen"
Identifier "SCREEN"
Option "AutoServerLayout" "on"
Device "RADEON"
Monitor "Monitor-DisplayPort-0"
EndSection
Section "Screen"
Identifier "SCREEN1"
Option "AutoServerLayout" "on"
Device "RADEON1"
Monitor "Monitor-HDMI-0"
EndSection
Section "ServerLayout"
Identifier "LAYOUT"

Screen 0 "SCREEN"
EndSection
Thanks in advance,
Zoltán Böszörményi
