I could only use LTS Kernel, had to downgrade it as well

[armaninux]

I have a Beelink U59 mini pc. Since kernel 6.11 I had to resort to the LTS kernel because the pc would become randomly unusable after a few minutes or seconds (everything would freeze in ugly green horizontal lines on top of a garbled incoherent mess of pixels).
Now the same thing happened with the LTS and I had to downgrade to 6.6.72-1. It wasn’t easy: I had to access the tty upon reboot and be quick enough to avoid the salad-of-death freeze.
I’m not looking to a solution to the issue. I would like to know this: is there a way to automatically exclude the LTS upgrade every time I update everything else?

In /etc/pacman.conf set this:

IgnorePkg = linux linux-headers linux-lts linux-lts-headers

That should do the trick, I think.

Yes, as above. But I am not sure that would be a long term viable solution to run on outdated kernels and miss on bug and security fixes to avoid the issue.

Getting help from knowledgeable forum members here to troubleshoot the problem is the way to go.

That’s just like my opinion, man.

makes sense, but my preferred long term solution would be to ditch the beelink…

I would either replace the computer, or switch distros to a stable release that uses an older kernel. A rolling release distro may not be what that particular machine needs.

Debian 12, the current version, uses the 6.1 series kernel and will stay on that kernel for its entire supported life (around 3+ years from this point). And yes, Debian backports security fixes into its kernels. My current Debian system’s kernel was released March 6, 2025.
