I suppose that is true. Intel seems to think so as well as their low power n100 is about the performance of a 1500x.

Sure, not much per gen, but if you compare say a 1700x vs the current 9700x, you are roughly looking at a 3x improvement in single and multicore performance increase.

Not sure, but the tldr is try using a faster drive for you cache folder.

I will just say it uses an ARM A5 which was introduced in 2011. It is 32bit processor which could be problematic as most linux distros are moving or have moved to 64-bit. And most importantly only has USB2.0 ports.

Additionally once you figure out the environment variable you can add in to the .desktop file so it will launch from a launcher in that way, though updates will reset that.

On arch wiki is a page on wayland which includes info on toolkits, though you may need to figure out the x11 option it will include the variable/option needed. https://wiki.archlinux.org/title/wayland#GUI_libraries

X.org should sue, then settle for a lot of money and use it to support their projects.
