Question: is the amdgpu(4) manual page up to correct and up to date? https://man.openbsd.org/amdgpu
I set up an xorg.conf file in /etc/X11/xorg.conf and was trying to get AMDgpu working. The man page uses "Device" as the section. This worked as root but not a normal user. When I changed "Device" to "OutputClass," X loaded without error as a normal user. Also, the man page does not mention setting machdep.allowaperture=1 in /etc/sysctl.conf cat /etc/X11/xorg.conf Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" Option "DRI" "3" Option "TearFree" "true" EndSection #copied from /usr/X11R6/share/X11/xorg.conf.d/10-amdgpu.conf #Section "Device" # Identifier "AMDgpu" # Driver "amdgpu" # Option "DRI" "3" # Option "TearFree" "true" #EndSection Section "Files" FontPath "/usr/local/share/fonts/spleen/" FontPath "/usr/local/share/fonts/ghostscript" EndSection 6.8 GENERIC.MP#98 amd64 As a normal user, and using "Device" X fails with "No devices detected. If I leave out the section completely, X goes through mode setting and chooses Radeon.
