Re: Can not boot to desktop when I use AMD graphics card on Debian forky

> When I use an AMD graphics card, I can't boot to the desktop on Debian forky. The reason is that the built-in graphics card driver of the system doesn't support the DRM feature. I would like to ask why Debian doesn't use simpledrm? When I open CONFIG_FB_SIMPLE and CONFIG_DRM_SIMPLEDRM, the system can start normally.

Which AMD graphics card? Fresh installation, or having been doing this for weeks
or months? Different one have different needs and quirks. Please show us:

	lspci -nnk | grep -A3 VGA
	ls -1 /sys/class/drm	# one, not el
	inxi -GSaz --vs # from DE X terminal with your custom kernel
	inxi -GSaz --vs # from vtty with stock kernel
