Please, this question has not been answered, I have read them all and none seems to work for me.

I have a headless system Ubuntu 20.04 with Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8570D]

and I have installed the

sudo apt-get install xserver-xorg-video-dummy

with changes to the xorg.conf

I am stuck with max resolution of 1360x768

Any ideas how to get higher resolution?

  • This might help the discussion. The link suggests the solution: $xrandr --fb 1600x900 It gives me the following: xrandr: Failed to get size of gamma for output default xrandr: screen cannot be larger than 1360x768 (desired size 1600x900) – stevem0 Dec 15 '20 at 15:42
