Sure sounds like an Optimus [0] issue. This plagued me for a long
time on Ubuntu (back in the 12-16 releases) but seems to be all
sorted now. Try disabling the NVIDIA card in the BIOS and see if you
are at least able to use higher resolutions via the built-in GPU.

Should I manually load this module at boot time? Does anyone know WHY
the i915 won't load at boot?
With 8.2 on this same machine, the Intel graphics was loaded.
Finally resolved -- YAY!
Using info from a reply by Christian Labisch
on a Red Hat discussion
thread. Using the
|i915.alpha_support=1|
|parameter on my kernel line. And, I removed the "nomodeset". I have not
done anything about "nouveau" or my NVIDIA card yet.

[CentOS] Graphic setup issues...help wanted
The problem. I can NOT change my screen resolution from GUI. I boot to multi-user, then get "into" graphical. First, some background. My original install of CentOS 8 -- maybe 8.2? -- about 3 months ago -- went pretty well but I kept having lockup issues. No issues with graphics using intel graphics or sound using either aplay at command line or GDM. (I also have NVIDIA which I have not configured.) I upgraded to 8.3 at some point. Still all OK with graphics but still lock up issues. At some point, I decided to start completely over and did a clean install of 8.4. I am now using CentOS8 Stream as my primary repo. Some questions? When I first boot, where is the probe of my video card done? Looking at DMESG, I couldn't determine this. When I "start" graphical, I get the following messages which are apparently related, from Xorg.1.log module loading section...
