Hi all, I got a new HP laptop (455 G7) and put latest GhostBSD (20.04, based on 12.1 release) on it. During installation, the only graphics selection that didn't fail was 'scfb', which I'm still using. AFAICT from my research, Renoir is supported by latest drm driver/module, so I installed that ( https://github.com/FreeBSDDesktop/kms-drm/tree/drm-v5.0-fbsd12.1). "pciconf -lv" shows: vgapci0@pci0:5:0:0: class=0x030000 card=0x8730103c chip=0x16361002 rev=0xc2 hdr=0x00 vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]' device = 'Renoir' class = display subclass = VGA I did quite a bit of research (or so I claim ;-)), with mixed results, but not success, I'm afraid. I have "kld_list ... amdgpu.ko" in my /etc/rc.conf, I've moved the position in the line around other items (linux*, cuse), w/o change some of the attempts I made: 1) remove all xorg.conf files (recommended in several posts) amdgpu isn't loaded, Xorg immediately falls back on scfb (I can post log if required) 2) use this xorg.conf: Section "Device" Identifier "Card0" Driver "amdgpu" BusID "PCI:5:0:0 EndSection ... produces this in the log: [ 8.577] (II) AMDGPU: Driver for AMD Radeon: All GPUs supported by the amdgpu kernel driver [ 8.577] (--) Using syscons driver with X support (version 2.0) [ 8.577] (++) using VT number 9 [ 8.589] (II) AMDGPU(0): [KMS] drm report modesetting isn't supported. [ 8.589] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support [ 8.589] (EE) Screen 0 deleted because of no matching config section. [ 8.589] (II) UnloadModule: "amdgpu" ... and the screen stays in text mode. 3) I tried removing all the config files in /usr/local/{share|etc}/X11/xorg.conf.d, same result as in 2). I'd appreciate some advice/pointers as to what I could do to get this card working ... then I'll follow up about the touchpad :-) TIA Michael -- Michael Schuster http://recursiveramblings.wordpress.com/ recursion, n: see 'recursion'
