====== Linux Netbook Fixes ======
Applies randomly to these crazy netbooks that run a display rotated 90 degrees like a tablet.  It's really dumb.  The Teclast N4k had a normal screen rotation

  * Chuwi Minibook X N100/N150
  * KOO Tigers Mini-laptop 8-inch
  * OneMix 3

//** I broke it, got an N150 and this KOO Tiger thing **//

Intel updates to firmware and drivers pretty much remove all the issues outlined in 2023.  KB backlight enable moved to the top of the keyboard. FN-F5

I threw up some scripts I built below.  They may break things, read thru them.  If I get motivated I might keep cleaning them up, but I don't set these up that often, it's more around remembering the handful of changes needed to get the screen to rotate properly, and adjusting the touchscreen on wakeup from hibernate/sleep.

I have a couple of other tweaks around runnig 'FIX' (touchscreen) after logging in on resume.  Nothing really crazy I fix the stuff as it annoys.  I actually am starting to get attached to the KOO Tigers thing.  This is my preferred form factor, all the ones I've owned were underpowered and all but the OneMix 3 just died for one reason or another.

Update 2023-12-26

//**After a few weeks of heavy use**//

The half-screen after sleep/hibernate/low-power/screen-dim issue is pretty brutal. What would happen is on wakeup the screen would split in two the bottom half would be a blurry mess that seemed to clean up as you typed frantic xrandr commands to try and get it sane. I went so far as to create a hot-key ctrl-alt-f that made the xrandr call I could bang easily sometimes requiring 5 or more tries until the screen was sane.  With the installation of the SID kernel (Debian 6.6.8-1 (2023-12-22) x86_64 GNU/Linux) this issue appears to have been resolved.


So I will be updating a few things below, but as of now I am actually happy with this machine running vanilla debian with a number of tweaks.  I have *everything* working and the latest kernel from SID  seems to have resolved the crazy half-screen pixellation issue.



===== BIOS =====

Hit F7 At the Chuwi Screen \\
ESC/DEL seems to work on the new N150
===== Installing Linux/Debian =====

A couple of scripts to to the fixes.  Might blow shit up, but a good baseline.

==== Debian 13 / Trixie ==== 
I'm running KDE Plasma.  For other desktops YMMV.  Some things changed over bookworm.  Pretty similar to below 

Scripts above should get most of it.  You'll need to read them, this is all one-shot stuff.  Hibernate and other

==== Better Screen Fix ====

The Debian 6.6.8-1 (2023-12-22) x86_64 GNU/Linux kernel from sid, seems to correct the screen problems

  * Add the sid repo to /etc/apt/sources.list
    * deb http://deb.debian.org/debian/ sid main contrib non-free-firmware non-free
    * deb-src http://deb.debian.org/debian/ sid main contrib non-free-firmware non-free
