[SOLVED] VGA Monitor not recognized after CPU update to Ryzen 5600G

Hello!

I have an ASRock B450M Pro4-F motherboard that I have been using with a Ryzen 3 3200G, one HDMI monitor, one VGA monitor.

I do not have a dedicated graphics card, I'm using onboard graphics.

Today I installed a new CPU, Ryzen 5 5600G

Since then, it acts as if the VGA monitor doesn't exist

(the VGA monitor is recognized as "DP-1" in xrandr)

DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm

My "mesa" package is up to date.

Here are some other commands I've seen people mention

$ lspci | grep VGA
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne (rev c9)

How else would I go about troubleshooting this?

Thank you!

This is dmesg output after I plug in the monitor

# dmesg
[ 1467.410361] [drm:dc_link_detect_helper [amdgpu]] *ERROR* No EDID read.
[ 1475.133094] kauditd_printk_skb: 5 callbacks suppressed

I updated the Motherboard's BIOS from 2.40 to 2.80 and that seemed to do the trick
