If you can somehow do an upgrade to 20.10 beta which has kernel 5.8, I think that your issues have a good chance of being fixed.
I have an Acer Aspire 5 4700U octacore APU, graphics included on-board. I was unhappy with 20.04. The upgrade to 20.10 fixed my issues: * Kernel 5.8 succeeds (where kernel 5.4 failed) detects that I need an amdgpu video driver. * Suspend followed by Resume works on 20.10; it did not on 20.04. * Power management works on 20.10; it did not on 20.04. Finally, I can close the lid, open the lid, walk away, come back - all these power mgmt functions work just as well on Linux as they did on Windoze. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1895197 Title: amdgpu fails to load Status in linux package in Ubuntu: Confirmed Bug description: This happens on boot, additionally I get a black screen (the boot happens on, I have an encrypted partition which I can unlock, but there's no feedback when unlocking). nomodeset works around this problem.
