I am hoping someone on this list might know something that could help me
configure the Intel HD 630 graphics controller.
I recently needed to upgrade my motherboard due to signs of failure (it
was over 11 years old). I was running Ubuntu 20.04 LTS with the stock
5.4 kernel and a GT220 video card using the nvidia-340.108 driver. The
ethernet adapter in the new motherboard was not supported by the 5.4
kernel, so I updated the HWE (to 20.04.3) which comes with the 5.11
kernel. I then discovered that the nvidia-340 driver will not compile
with any kernel >= 5.5 (seems to be a known issue), so I tried switching
to the built-in Intel video:
Graphics:
Device-1: Intel driver: i915 v: kernel
Display: x11 server: X.Org 1.20.11 driver: fbdev
unloaded: modesetting,vesa resolution: 1920x1080~60Hz
OpenGL: renderer: Mesa Intel UHD Graphics 630 (CML GT2) v: 4.6 Mesa
21.0.3
This "seems" to work, but I have noticed that black text on red
backgrounds is blurry and I don't remember this issue with the GT220
card. Some web searching leads me to the conclusion that the Intel
video is not configured correctly (something to do with chroma
subsampling YUV 4:2:0 vs RGB 4:4:4). My search found many examples of
this by others, but no solution as to how to fix it. One user's fix was
to ditch the Intel video and install a separate video card.
Does anyone know how to configure the Intel GPU on linux to RGB mode?
The TV display is 1920x1080@60Hz, no UHD or 4K required.
If that is not possible, then a recommendation for an Nvidia video card
that has a working linux driver for the 5.11 (and later) kernel.
