Hi Andy, I tried it but got the same error. I am pretty sure I got the correct copy of the driver as can be seen in the log. Interesting note, when rhgb was on during boot, the word CentOS 6.8 at the bottom right of the screen was orange instead of white. I wonder if the kernel was aware of there being a custom driver. I do appreciate the help. While I have never written drivers, my experience with .so files indicates that they added something to the file which invokes the driver to reference xf86LinearVidMem which was never added to that driver. yum --disablerepo=\* --enablerepo=cms4all install xorg-x11-drv-mach64 Loaded plugins: fastestmirror, refresh-packagekit Setting up Reinstall Process Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package xorg-x11-drv-mach64.i686 0:6.9.4-10.el6 will be reinstalled --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================== Reinstalling: xorg-x11-drv-mach64 i686 6.9.4-10.el6 cms4all 69 k Transaction Summary ============================================================================================================================================== Reinstall 1 Package(s) Total download size: 69 k Installed size: 168 k Is this ok [y/N]: y Downloading Packages: xorg-x11-drv-mach64-6.9.4-10.el6.i686.rpm | 69 kB 00:00 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : xorg-x11-drv-mach64-6.9.4-10.el6.i686 1/1 Verifying : xorg-x11-drv-mach64-6.9.4-10.el6.i686 1/1 Installed: xorg-x11-drv-mach64.i686 0:6.9.4-10.el6 Complete!
