Radeon 5450 OpenGL compatibiliy

Question

My question is related to this one: How to get AMD Radeon HD 5450 drivers on Ubuntu 16.04

My setup is working, though really not optimally; the display is SO slow with CAD software!

I am using Radeon HD5450 on Ubuntu 16.04 with the 'out of the box' driver, and I can't manage to improve it.

I think it has to do with the radeon driver, but I don't know how to adjust it.

One way could be to disable it and fold back on the onboard gfx card when working on CAD software (yes, it is that bad!)...

Answer 1

I have had to re upgrade, because I couldn't go back.

With the base components from 18.04, the radeon card is working again, and so is the CAD software.

So I can't explain why or how, but it seems the radeon open source driver is better in 18.04 than it was in 16.04.3.
