Long awaited, I guess, but is it worth bothering? https://www.phoronix.com/scan.php?page=news_item&px=AMD-Catalyst-15.5-Linux As we all know, there is some work done to get 14.12 working for Fedora 21 / 22 systems already. More info in this blog: https://bluehatrecord.wordpress.com/2015/03/22/installing-the-proprietary-amd-catalyst-14-12-fglrx-driver-on-fedora-21-for-installation-with-kernel-3-19/ Quoting:
Yeah, I’m working on Fedora 22; I just installed the Fedora 22 KDE Plasma Desktop Spin from scratch on my AMD system and so far, unfortunately, the driver installs properly but throws a segmentation fault at startup, preventing the display of any GUI whatsoever. I’m looking into it and will post more soon, but in the meanwhile, I don’t advise moving to Fedora 22 if you depend on the Proprietary Catalyst driver. Hopefully that advisement will be short-lived.
Please vote / support AMD Catalyst 15.101 package for Fedora 22 on X.Org X11 Server 1.16 from RPMFusion.
