Short guide to setup Archlinux on a Linx 12x64 Cherry Trail Tablet
What doesnt work:
Bluetooth Audio (problem with setting bitrate, sending and receiving files works) Cameras front and rear
Installing Arch Linux
Set up arch linux on a bootable USB stick/SD card and copy the files in this repository to the card as you will need them later, proceed with an install as normal.
Wifi Drivers
I used a microusb to Ethernet dongle for connecting to the internet during install, however if you do not have one you can set up wifi drivers by copying 4345r6nvram.txt to /lib/firmware/brcm/brcmfmac43455-sdio.txt and copy brcmfmac43455-sdio.clm_blob to /lib/firmware/brcm/. restart the driver with modprobe -r brcmfmac && modprobe brcmfmac.
Grub bootloader
If using Grub as a bootloader use the 64 bit EFI setup method (older models use 32 bit EFI so you will need to check) use https://wiki.archlinux.org/index.php/GRUB#UEFI_systems as a guide to installing the bootloader.
Before Restarting after Install
Tablet has habit of suspending every few seconds wen used with the foldable keyboard. Editing /etc/systemd/logind.conf handlesuspendkey and handlelidswitch to ignore fixes this issue (though it makes it impossible to suspend by closing the lid unfortunately, maybe there's a workaround?)
For screen rotation to work properly in Gnome or KDE copy 61-sensor-local.hwdb to /etc/udev/hwdb.d/61-sensor-local.hwdb
Reboot the Tablet
