With RHEL6, instead of the default open-source (radeon ?) drivers, I am using
fglrx-x11-drv-15.1?-?.el7.elrepo.x86_64.rpm
kmod-fglrx-15.1?-?.el7.elrepo.x86_64.rpm
from http://elrepo.rog, for 2 reasons:
1. to be able to lower the (native) display resolution (radeon is unable to do render correctly)
2. graphics performance (radeon is much slower than fglrx, opengl ?)
I guessed the AMD hardware of my DELL PRECISION M6800 with following command:
$ lspci -nnk | grep -i vga -A3
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Saturn XT [FirePro M6100] [1002:6640]
Subsystem: Dell Device [1028:15cd]
Kernel driver in use: fglrx_pci
Kernel modules: fglrx, radeon
Now the question: since elrepo does/can not provide the fglrx rpms for el7, which drivers can I use for RHEL7, (7.3. 7.4 7.5) ?
