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

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 :



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

(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.
