Hi Max, sorry for the delay. I’m currently running Ubuntu 18.04, everything works, except the screen rotation. The battery indicator works well and this version of Ubuntu is very easy on the battery. These are fixes I received from around the web, so none of it is my own creation, but they seem to work for the Chuwi Hi-10 Plus:

Fix Touch Screen – Be warned, the touch screen does not work well, it is a bit erratic, so not an awesome feature on linux.

sudo apt-get install git (If Required)
git clone https://github.com/onitake/gsl-firmware.git
sudo cp /gsl-firmware/firmware/chuwi/hi-10_plus/silead_ts. /lib/firmware/

git clone https://github.com/onitake/gslx680-acpi.git
cd gslx680-acpi
make
sudo cp gslx680_ts_acpi.ko /lib/modules/$(uname -r)/kernel/drivers/
sudo insmod ./gslx680_ts_acpi.ko

At this point the touch screen should be working!
Then do…

sudo apt-get install xinput-calibrator
xinput_calibrator

sudo gedit /usr/share/X11/xorg.conf.d/99-calibration.conf

and paste your config output, or the sample and save:

Section “InputClass”
Identifier “calibration”
MatchProduct “Silead GSLx680 Touchscreen”
Option “Calibration” “5 1958 26 1545”
Option “SwapAxes” “0”
EndSection

Then to save all the settings

sudo echo ‘gslx680_ts_acpi’ | sudo tee -a /etc/modules
sudo depmod

Sound Issue:
git clone https://github.com/plbossart/UCM.git
sudo cp -rf ~/UCM/bytcr-rt5651 /usr/share/alsa/ucm
sudo cp ~/UCM/bytcr-rt5651/asound.state /var/lib/alsa
echo “blacklist snd_hdmi_lpe_audio” | sudo tee /etc/modprobe.d/blacklist_snd_hdmi_lpe_audio.conf

Reboot and sound should work!

Hope that helps
