i want enable randr option on centos7 64-bit system. on googling issue seems nvidia supports randr1.1 , randr 1.2 centos7 default has randr 1.4 installed.

relevant details below:

[root@box1 ~]# nvidia-smi -l gpu 0: geforce gt 710 (uuid: gpu-999ed32f-aef2-0d96-57a5-c91f21c6a15a)  [root@box1 ~]# cat /var/log/xorg.0.log | grep -i randr [   368.340] (**) extension "randr" enabled [   368.874] (--) randr disabled   [root@box1 ~]# xrandr -v xrandr program version       1.4.

my /etc/x11/xorg.con file below:
