"Haha misogyny"
Yeah, it always reminds me that I did a kernel benchmark for gaming a couple of years ago and the differences were within the margin of error. https://web.archive.org/web/20220602144244/https://www.reddit.com/r/archlinux/comments/utfazn/results_for_the_kernel_benchmarks_in_gaming/
I don't get it, CachyOS is probably improving performance in the low single digit percentages. Why are people so crazy about it?
But you are getting an image to your monitor using the GPU?
Firefox for Android partially supports PWAs.
I know that KeepassXC has an automatic favicon downloader built-in and it's open source. Maybe check out it's code.
"User friendly" Arch Linux mostly means hiding away essential aspects of the distro and when things break the user is clueless, which in the end is the opposite of "user friendly".
I'd argue the optimizations are pointless. According to this benchmarks they are: https://www.phoronix.com/review/cachyos-linux-perf/5
What is it that "doesn't work"? Can you describe precisely what you're expecting, what's happening instead and what you have done?
Also maybe boot from a Live ISO, if that doesn't work, it's probably a hardware issue.
And is the GPJ properly seated in the first PCIe slot and has enough power?
Define "insecure".
What security problems?
It actually doesn't really matter.
