In not that *someone more knowledgeable*.. but me here, I'm actually running my screens without any xorg.conf and for the fact that Alexis said "Option Rotate settings in xorg.conf is not working" I would try to make it with just xrandr.
An other trick that Alexis could try before to give it up with xorg.conf is the following: Section "ServerFlags" .. Option "AutoAddGPU" "on" .. EndSection (to solve for the second gpu) I see also now that Alexis mention the file "20-amdgpu.conf", I personally have only "InputClass" and "OutputClass" in these kind of file but I wait for *someone more knowledgeable*..;) -Dan Zé Loff <zel...@zeloff.org> wrote: > On Mon, Oct 28, 2024 at 06:51:19PM +0100, Alexis de BRUYN [Mailing > Lists] wrote: > > Hello Everybody, > > > > On a system running -current with 2 video cards, I want to use > > arandr to configure grafically at least 10 monitors and because the > > "Option Rotate" settings in xorg.conf is not working. > > > > [ 25.614] (--) PCI:*(3@0:0:0) 1002:7312:1002:031e rev 0, Mem @ > > 0xa0000000/268435456, 0xb0000000/2097152, 0xb5800000/524288, I/O @ > > 0x00007000/256 [ 25.614] (--) PCI: (12@0:0:0) > > 1002:7312:1002:031e rev 0, Mem @ 0x80000000/268435456, > > 0x90000000/2097152, 0xb5500000/524288, I/O @ 0x00004000/256 > > > > $ cat /etc/X11/xorg.conf.d/20-amdgpu.conf > > Section "Device" > > Identifier "Card3" > > Driver "amdgpu" > > BusID "PCI:3:0:0" > > EndSection > > > > Section "Device" > > Identifier "Card12" > > Driver "amdgpu" > > BusID "PCI:12:0:0" > > EndSection > > > > In menu "Outputs" menu of arandr, only 6 DisplayPort are shown. > > > > $ xrandr --listproviders > > Providers: number : 1 > > Provider 0: id: 0x5a cap: 0xf, Source Output, Sink Output, Source > > Offload, Sink Offload crtcs: 6 outputs: 6 associated providers: 0 > > name:AMD Radeon Pro W5700 @ pci:0000:03:00.0 > > > > I have tested the same setup with an Ubuntu live CD, and 12 DP were > > recognized. > > > > Thanks for your help. > > > > $ cat /var/log/Xorg.0.log > ... > > [ 21.354] (II) AMDGPU(0): [KMS] Kernel modesetting enabled. > > [ 21.476] (II) AMDGPU(1): [KMS] Kernel modesetting enabled. > > but > > > [ 21.543] (EE) Screen 1 deleted because of no matching config > > section. > > and then > > > [ 21.575] (II) UnloadModule: "amdgpu" > > I'm guessing, and someone more knowledgeable might correct me, but I'd > say you probably can't get away with the default configuration, and > need to explicitly configure the Screens for those two Devices. >
