Folks:
This is a shot in the dark, but I'll try it.
I have a new ASUS Prime H570M-Plus/CSM motherboard (LGA1200 socket) with
an Intel i3 10100 CPU (10th gen, with UHD630 graphics) in it. I have a
DVD drive in it and a 500GB SSD. I've used a live CD/DVD in this machine
to install Debian 11 to the SSD. It boots, and does a couple of lines of
the usual boot chatter (ramfs and such), and then the video simply stops
(no signal). I've tried two monitors, various cables. The install went
without a hitch, so I know that at least the installer runs without
difficulty, no video glitches.
I know that as Debian starts up, it adjusts the video several times on
my main desktop as it boots. This is about the point where the new
system simply stops outputting video. I'm afraid that there's an issue
here where the kernel version (5.10.xx) is too far back to handle the
way the i3 handles video mode changes, or something like that.
Does anyone have a clue about this?
Paul
