Chuwi ubook with JingOS (not well with the pen)

The pen does not work with chromium to annotate pdf. for taking notes with stylus labs, it got ink before the pen touch the screen, where can I adjust it?
wifi, bluetooth, audio and others are good.

os 0.9.1

Hi @alpc30 ,
do you confirm it has the following hardware?

  • Intel Celeron “Gemini-Lake” N4120 quad-core 1.10 - 2.60 GHz
  • Intel® UHD 600
  • Display IPS 11.6" 1920 * 1080
  • 8GB RAM
  • 256GB SSD
  • Windows 10 x64
  • Battery 3500mAh

And JingOS works well?
I don’t know how to solve input lag of original Chuwi PEN, but I will forward your request to Admins.

Unfortunately, JingOS has no way to adjust the sensitivity of the pen on the software side yet, which could solve your problem of drawing before touching the screen. You will have to check your hardware.

CPU: N4100 1.1Ghz
Another problem: when extending the screen with an HDMI cable, it works well. But for a VGA cable, it flashed for a while and pop up the ubuntu login window.

it works well when I swich to windows 10.

Hi @alpc30 ,
did you tested also a Generic Kernel from Ubuntu PPA?
