Rock64 + Klipper + KlipperScreen Instructions
#1
    Rock64 + Klipper + Fluidd + KlipperScreen
After much ado I finally got everything working. I tried many flavors of linux and the only one that had decent video drivers was Ayufan's prerelease version 0.11.2.-1187. 
I purchased several Rock64's some years ago for $20 off amazon. It was a security appliance with power supply. Used a couple for retro gaming. Next to print enclosure and mounting.

Here's what you need. (I supplied links at the end)
*Rock64
*Linux Favor Ayufan= focal-minimal-rock64-0.11.2-1187-arm64.img.xz or newer.
*klipper screen = Kuman 7" HDMI 1024x600 - Amazon or aliexpress
*Download Kiauh and follow instructions. Seems all manual installs have been removed for search engines.

KlipperScreen Error I encountered -
xf86OpenConsole: Cannot open virtual console 2 (Permission denied)
Fix that worked ->
sudo bash -c "echo needs_root_rights=yes>>/etc/X11/Xwrapper.config"

Some xorg random notes -
find monitor number via ssh do not type $
$ export DISPLAY=:0
$ xrandr --listmonitors
list display resolutions
$ xrandr -d :0
$ xrandr -display :0.0 --listmonitors
>output
Monitors: 1-- 0: +*HDMI-1 1920/476x1080/268+0+0  HDMI-1
