Do you have more information on your graphics card (manufacturer/model)?

Its ASUS DUAL-RX580-O8G https://www.asus.com/Graphics-Cards/DUAL-RX580-O8G/specifications/

Can you also print vbios_version?

# cat $(find -name 'vbios_version') 115-D009PI2-101

# lspci|grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X] (rev e7)

Try this

This solves the problem! Everything looks to be working fine again. Thank you!

If you need any more info I'll gladly help.
