nothing happening when touching display. i think i've installed all possible packages from repos and aur.
btw, there is no /opt/vc directory in aarch64 image.
so question is: how to run 5 inch xpt2046 touchscreen in aarch64 archlinux on rpi 3 b+?
it's running using ads7846 in raspbian, but ads7846 does nothing in archlinux
