How to install arch on a flash drive to run on any hardware?

Question

linux

Purpose: a flash drive with arch-em, running on any hardware, for everyday tasks.
There is a flash drive with LVM on LUKS on it (I already realized that I should refuse), on LVM Arch. I skated it for more than a week on real hardware (on my main PC), installed a proprietary driver for Nvidia, set up a lot for myself, everything flew, I could not get enough of it. But when it came time to actually use it, it didn't start on the first computer: "support for cores revision 0x17 and 0x18 modul param allhwsupport=0...". Computer with AMD stuffing. A similar error occurs with the following attempts: i3 and optimus, atom. What is this error related to and how to solve it (preferably without chroot, if possible)?
How do I get things done (ready to reinstall everything)? What are the features of installation other than the default path? For example, should I install drivers for all cards or will they conflict with each other and should I be limited to the standard mesa?

Answer 1

For example, should I install drivers for all cards or will they conflict with each other and should I be limited to the standard mesa?

why not, install all free firewood on video:
or is it better to immediately put the xorg-drivers group :
in general, see Xorg#Driver installation
You can also look at the topic on the Arch forum Portable Arch , although it was written a long time ago and in some places it is a little outdated, but if you ask on the forum, I think they will direct you in the right direction.
Maybe you should just modify archiso to suit your needs. Once you set it up, assemble it and it will work faster as it is loaded into the RAM.

Answer 2

If you want to run on any hardware, then proprietary firewood on the video is contraindicated - because of them, the gui will not take off if the video does not fit.
