#242036 — No video after boot

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

Good morning

Have you tried booting recovery mode?

If you think the problem is kernel, 5.14 is available in backports.

Recovery mode generates slightly more jabber on screen, but then does 
the exact same thing-- video signal disappears.

There's a *more* advanced kernel in backports? I thought backports was 
for old stuff. And I've never used it, not sure how to do it. The other 
problem here is that, if I could actually boot, I could update the 
kernel. But without being able to boot the drive, I can't quite imagine 
how I'd update the kernel.

Briefly, backports is a method of bringing newer stuff into stable, for 
people who really, really need newer. They are handled by a team who try 
to ensure that stuff in testing is working well enough that the rest of 
us should be able to use it with fewer problems than simply running 
testing.

I thought you were getting a terminal?   You said that you have another 
PC. So

Find a tutorial on adding backports to your sources.list, then how to 
use backports. I have an alias that installs backports:

sudo apt-get -y install --install-recommends -t bullseye-backports 
package

The tutorial should explain how to add a line to your sources.list,
# apt update,
apt search linux-image

check for signed images   (linux-image-5.14.0-0.bpo.2-amd64/now 
5.14.9-2~bpo11+1 amd64 [installed,local]   Linux 5.14 for 64-bit PCs 
(signed)

# apt-get -y install --install-recommends -t bullseye-backports 
(maybe???) linux-image-5.14.0-0.bpo.2-amd64    from my list of available 
images

Your suggestion was spot on. I plugged the new drive into my main 
machine, booted it, then configured /etc/apt/sources.list to accept 
backports. Updated. Installed the 5.14 kernel. Made sure it would boot 
from my main machine after that. Then took it out and plugged it into 
the new machine. Video works now. So it *was* a problem with the 5.10 
kernel and the onboard graphics from the i3 chip.

Thanks,

Paul

Pretty disappointing that a CPU introduced ~15 months[1] prior to the distro's
release isn't supported out of the box. That doesn't sound right. :(

Something to try: remove xserver-xorg-video-intel. If you find *.conf in
/etc/X11/xorg.conf.d/ containing 'Driver "Intel"', remove/rename the file.

Also, show us Xorg.0.log from before and after the try (use pastebinit to upload,
then provide URL here). It should be in /var/log/, but may be in ~/.local/share/xorg/.

For troubleshooting purposes only, you may need to try nomodeset on the Grub linu
line.

10th Gen IGPs shouldn't need backports, but I could be wrong, and they might.
