If I really need (proprietary)Catalyst/fglrx, then I use @Vi0L0’s very well maintained “catalyst-test” from AUR, notwithstanding manjaro, (downgrading Arch’s Xorg and/or Kernel versions if need be), on my slightly older stuff, 'cause it’s handy, and it works great.
But honestly, other than that, NO, I don’t bother with catalyst very much anymore, and neither does anyone else.
it’s time to get on with the more-or-less (opensource) amdgpu,… future for better or worse?
I just wish nvidia would do the same ! lol.
But then again, there’s always someone with a reason to cry about forever supporting something?
