Well, I got my user back to being able to use his system, but I've still got one issue: it's running on the VESA driver - there is *no* Catalyst build for this monitor, for CentOS 7. From a lot of googling, nothing's been done since the summer of '14 (lspci reports it as a FirePro V3900). Any thoughts, or pointers, as to if/how I can get X - he's running KDE - to see the full
