[SOLVED]mkinitcpio hook to detect video card and load only that driver

Is there a hook that will copy all three (intel, nouveau,and ati) common video drivers into the initrd and load the detected one at boot time?

This would be extremely useful on a CD/USB install of Arch

EDIT: I guess hwdetect would need to be copied to the initrd as well

That could have been answered with a simple mkinitcpio -L and maybe a few runs of mkinitcpio -H <hookname>

Plus I'm not sure such a hook is even necessary.  AFAIK the appropriate driver for X is chosen by X, and then not until X is run.

Thanks!  I'll assume you're talking about archiso_kms. That looks like it might do it.

Actually, I had never heard of archiso_kms.  It doesn't exist on my installed system.  TBH, I trying to lead you to see that there was no such hook.

Good thing I didn't say so outright. I booted to the installer cd, and it does seem like it should do the trick.

I didn't think there was a builtin hook either, I was hoping for someone's personally built solution.

KMS works fine for me on individual machines that I setup, but, for a portable soultion, I wasn't sure if the correct way to go about it was to just load all video modules and allow the failures
for the hardware that doesn't exist.  The solution in archiso seems to be along these lines.

If anyone has a better one I'm still interested.  I might write my own hook if I find that archiso_kms is lacking.

That's why this is already done on the official Arch ISO: https://projects.archlinux.org/archiso. … rchiso_kms

Thanks...I know.
