problem with amd GPU

21 January 2024, 17:39:29

hello. artix xfce open rc. my graphics card is rx550, motherboard - asus p8h61-m lx. i update it to the last bios from official asus site of course. and i can't enter the bios, more precisely, i think i'm entering the bios, but the graphics card doesn't display the image on the monitor, but if I don't try to enter the bios, the image on the monitor will only appear when the GRUB loads. it is very strange problem, cause bios dont displayed, but os displayed. and in artix i cant change the resolution. its only 640x480. i also installed xrandr, and when i tried to set another resolution, the output was - "xrandr: cannot find mode 1024x768" (1280x720,etc). but of couse my monitor support this resolution, and with intel hd graphics i can enter bios, etc. and it is not problem in rx550, cause in other pc it works fine. maybe troubles with resolution because im should install some driver(preferably open source)?

The way you've written that is hard to read.
Like a stream of your unconscious thought rambling out with no breaks and no capital letters to help make out the sentences.

Maybe add

Code: [Select]

if [ ${grub_platform} == "efi" ]; then
	menuentry "Firmware Setup (UEFI)" --class recovery {
		fwsetup
	}
fi

to the end of /boot/grub/grub.cfg and try the option to boot back into the UEFI / BIOS ?

Or use the integrated GPU and look in the UEFI settings for a way to specify the PCIe GPU ?
