You can still use an xorg.conf with xorg-1.20.x, but the recommend method is to let auto-detection work. what i do is drop configuration snippets in /usr/local/etc/x11/xorg.conf.d/. for example when testing out adjustments to my GPU I have a file 10-amdgpu.conf which includes the pertinent configuration section for that device - for example: Section "Device" Identifier "Card0" Driver "amdgpu" BusID "PCI:38:0:0" EndSection hope this is helpful, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
