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.
