[CentOS] how to use intel UHD 630 display driver on CentOS 7.8?

Hello all,

 

I just installed CentOS 7.8 on ASRock B460M Pro4 board. CPU is i5-10400.

The display device is inside the CPU and the max resolution is 4096x2160 for
HDMI.

But when I connect my small screen (max full HD), the display resolution is
only 800x600.

>From seeing some info here, I installed EPEL for yum, and inxi.

The "inxi -G" command's output is like this :

 

Graphics:

Device-1: Intel driver: N/A

Display: x11 server: X.Org 1.20.4 driver: vesa

unloaded: fbdev,modesetting resolution: 800x600~75Hz

OpenGL: renderer: llvmpipe (LLVM 7.0 256 bits) v: 2.1 Mesa 18.3.4

 

So there is no intel driver and the vesa fall back driver is being used.

 

I tried adding i915.alpha_support=1 in grub.cfg
(https://access.redhat.com/discussions/3410491)

(so that i915 fall-back driver can be used) but it was the same.

The intel site only provides driver for windows.

 

Could anyone give me some advice? 

(the board/cpu has no display problem when using CentOS 8.2)

 

Thanks for reading.
