Hi Geert, Thank you so much for your prompt reply.
Your suggestion it could be a monitor problem provided the clue it could be the 11-year old model used (Acer X223w) that was causing the problem. Swapped for a more current unit (Dell U2414H) and screen is nicely centered now. That still leaves the problem why dmesg shows '[ 1.349124] [drm:amdgpu_pci_probe [amdgpu]] *ERROR* amdgpu requires firmware installed]' Which firmware? Just for interest I had once tried to edit the screen resolution config file back in 2001 (Red Hat) and the result was so bad I swore never to touch the file again! Thank you again for your help.
