Hello,
I saw in the CentOS 6.6 release notes that the Xorg ABI has changed but that "This should not concern anyone who uses the default drivers shipped with CentOS." I'm using the ATI drivers in Base but X still fails when I boot a CentOS 6.6 kernel. I was hoping this is a known problem that would get fixed with a kernel update but I'm still having problems with the 2.6.32-504.1.3.el6.x86_64 kernel. Relevant info below. Any ideas?
Thanks, Darby
