I was booting the latest-greatest 5.15.0-102.110.5 but for an unknown reason and without any cause, X-Windows stopped starting correctly, as if did not see any video card or drivers. I have X-windows but the font is huge and it does not see external monitors. Looks like a driver issue.
So I had to roll back to 5.15.0-101.103., set that as my default kernel. X-windows (gnome 40) correctly starts there. Everything works.


How, from 101.103 do I upgrade to a newer kernel version? dnf update does not do anything. Am I stuck on 101.103 forever?

It is not for 'an unknown reason': the reason is that you're manually shoving things in/updating things. That's the reason.

You, again, do not manually update things, as you've been told before. The ENTIRE POINT of a server distro is stability, not just shoving things in for no reason. You wait for Oracle to update the kernel. This is very similar to your other thread:
https://www.linuxquestions.org/quest...ll-4175725628/

...where you manually updated the kernel, and were surprised you didn't have headers and other things needed to update the nVidia driver, for graphics on a server-distro.

Again: use a consumer distro like Fedora. Otherwise, you'll KEEP facing these same issues.
