You may refer to https://wiki.archlinux.org/index.php/ATI_Catalyst,
Catalyst does not support the newest Xorg servers. They do not update their
drivers much(or someone can say Xorg is changing their driver interface too
much) for what ever reason it won't work with newer Xorgs. And newer
Ubuntu's use newer Xorgs that might be your problem but I am not exactly
sure if you have time and knowledge I recon you try arch on a separate
partition. It gives you more freedom to configure which version of what
you's be using.
