    How to install AMD (R9 295x2) Graphics Drivers on CentOS 7.2?


      I use official RHEL 7 driver as follows:

      yum install fglrx64_p_i_c-15.302-1.x86_64_rhel7_64a.rpm

      aticonfig --initial 



      After reboot, CentOS (7.2) successfully restarted but failed on entering graphics mode.

      check /usr/share/ati/fglrx-install.log, it said:

      Unloading radeon module...

      rmmod: ERROR: Module radeon is in use

      Unloading drm module...

      rmmod: ERROR: Module drm is in use by: ttm drm_kms_helper radeon

      [Message] Kernel Module : Trying to install a precompiled kernel module.

      [Message] Kernel Module : Precompiled kernel module version mismatched.

      [Error] Kernel Module : Kernel module build environment not found - please consult readme.

      [Reboot] Kernel Module : dracut

      [Message] Driver : End of installation


      I searched on google, found some a post said the error is related with Secure Boot. But I checked in BIOS, Secure Boot option already has been closed.

      Can anyone give some suggestions?
