- RX 5500 XT
I was stuck on High Sierra with my GTX 1060 and purchased an RX 5500 XT to be able to upgrade.
I first updated directly to Catalina with the 1060 still in.
I then swapped the card, but the system didn't boot anymore.
I restarted with a fresh Clover config and was able to boot with latest FakeSMC, Lilu and WhateverGreen. The only thing needed is the "agdpmod=pikera" boot argument. (My clover config is absolutely empty otherwise!)
I had a lot issues with USB audio (cutting all the time), and the computer not waking up from sleep.
After a lot of trials, disabling Legacy USB Support and the Serial Port in the BIOS solved both issues!
It is now 100% functionnal, sleep working, two monitors ( 1 Displayport + 1 HDMI ) working at the same time.
I also fixed one of the last issue I had - low graphic resolution in Clover - by disabling CSM in the BIOS.
