Ubuntu 20.04 AMD GPU with Intel process stuck on 1024x768(4:3) Resolution

Question

I've installed Ubuntu with single boot option. I wasn't able to install Ubuntu straight away, I've had to use safe graphics mode option to install Ubuntu 20.04.After successful installation, I was presented with a black screen. Then I started Ubuntu again in recovery mode and tried to install AMD latest Ubuntu 20.04 drivers and I got the below error at around 97%. Command used to run AMD driver is below:

./amdgpu-install -y

Error Message I got is this

Building for 5.4.0-47-generic

Building initial module for 5.4.0-47-generic
Error! Bad return status for module build on kernel: 5.4.0-47-generic (x86_64)

I've tried the above method twice and have uninstalled the drivers. The below result is after uninstalling amdgpu driver from AMD site.

The interesting point is the result from the command:

sudo lshw -c video

Thanks in advance!

Solution

My situation is a little different since I'm using a headless server for crypto mining, but I was getting the same error message regarding amdgpu-dkms. I did manage to get 20.45 driver working on Ubuntu Server 20.04 using the following steps:

./amdgpu-pro-install --opencl=legacy,pal,rocr --headless -y

omit --headless if using desktop gui. errors will still be present

get mainline kernel update script

wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh

install kernel update script

sudo install ubuntu-mainline-kernel.sh /usr/local/bin/

run kernel update script

sudo ubuntu-mainline-kernel.sh -i

script will display most current kernel available and ask for confirmation to install. In my case it was 5.10.1-051001-generic

after reboot, mining software still didn't work. amdgpu didn't show up in lsmod so I did:

sudo modprobe amdgpu

and suddenly my mining software worked. haven't tried rebooting because I'm just so relieved that it started working.

I also installed kernel 5.6.19 at one point and ran update-initramfs -u

I don't think that had any effect but just mentioning it for completeness.

I've tried the latest version till date and that is 17-Sep-2020 which is present on AMD site and the AMD driver version is 20.30 and problem still exists. The good news is it didn't gave any error and installed it. One positive sign there, it may have helped someone with this update, but not me. Thanks!
