Can't get Radeon HD 7470 to be seen on Ubuntu - help me find replacement?

[puck2]

Thanks - I've tried to install but can't get past dependency requirements laid out in this document: https://drivers.amd.com/relnotes/amd-cat...ystems.pdf

I'm so close!

I ran catalyst, get the following:

Detected X Server version 'XServer _64a' is not supported. Supported versions are X.Org 6.9 or later, up to XServer 1.10 (default:v2:x86_64:lib32:XServer _64a:none:5.8.0-38-generic
Installation will not proceed.
