From messages I've seen on this problem, the lack of
/dev/dri/card0
is the crux of the issue but I have NO idea of how it gets created.
So, right now I'm stuck at a default resolution of 1024 x 768
Thanks for any help.
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.

Back again...I've taken a look at the CentOS forum thread but it
doesn't directly address my problem
OK, the problem is absolutely positively that the intel i915 module is
not able to load at boot time...re DMESG (I did finally get the sound
to work with appropriate firmware)
[ 78.597678] sof-audio-pci 0000:00:1f.3: init of i915 and HDMI codec
failed
other exploration showed me my system set up Intel as default VGA (or
not?)
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630
(Mobile)
01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [Quadro
T1000 Mob
grep . /sys/bus/pci/devices/{0000:00:02.0,0000:01:00.0}/boot_vga
/sys/bus/pci/devices/0000:00:02.0/boot_vga:1
/sys/bus/pci/devices/0000:01:00.0/boot_vga:0
my kernel line is:
GRUB_CMDLINE_LINUX="resume=UUID=a8b2287c-2f04-4447-a88f-52a8fa3439b5
nomodeset"
Command : lshw -c video
shows both cards unclaimed but NVIDIA first ???? ...
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
<https://access.redhat.com/user/13851731> 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.
