Re: Dual ATI Cards -> Half Working
Sorry ... don't have a solution but do have a suggestion ...
What's going to hamper you in whatever you do to solve this is that the 9200 does not have ATI Linux drivers anymore -- and is not going to. ATI dropped Linux driver support for that card a long time ago.
The Phoronix forums have an open source ATI driver forum where they do a lot of testing and tweaking. If you check there, you may find some settings you can tweak to do what you want.
Ubuntu 16.04 Mate, Mint 17.3; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
