CentOS

I can see the 'Header' directive in the docs page, just below 'H2WindowSize bytes'

The answer is "it depends". Each directive can be used in a certain "context". Some directives are per "server", others are per "virtual host". You can find out which is which by using this page https://httpd.apache.org/docs/2.4/mod/quickreference.html The letters on the far right of the page tell y...

It sounds like the hardware works in Windows, and also with the minimal driver that's used before the real GUI starts. Linux distros are probably starting off with the minimal driver and then loading something like 'radeon' or 'amdgpu' and suddenly it breaks because the video chip is not new enough ...

If you don't have all features, you need to check you have the correct list of packages starting with "gnome*".

Hard to help with what's been provided.

Can you double check which version of CentOS 8.x you are using, and also the kernel version?

There are too many problems to troubleshoot in a meaningful way. For the hardware, take the laptop apart, take out processor, memory, make sure every electrical contact is clean, make sure cooling is working correctly, reseat everything and see if the machine check is still there. If you can get to ...

It's also worth stating the filesystem type of the /Downloads directory, e.g. local using Ext4, or something else
The title bar say ~/Downloads, but vim is saying ~root/Downloads

I just found a way to look at the journal, which MIGHT show some meaningful errors
But this would only work on the system that has been booted, e.g. I think it would work if you could boot with console only
