    Screen flickering - Acer Switch 5

    Hi Friendly Ubuntu Users!

    This problem has been dogging me for about 10 months now. The problem comes and goes but lately it has been worse so it is time to post and seek help.

    I have an Acer Switch 5 which is a touch screen laptop. The screen has been flickering on me. Sometimes to the point that the computer is unusable. But normally it is tolerable.

    I have tried mostly used Ubuntu 19.04 and more recently 19.10 but I have also tried Linux Mint (most recent) and the same thing happens. This is a video I took showing what it is like with Linux Mint but it is the same with Ubuntu. Mint is based on Ubuntu, so this is not surprising.

    It is not always this bad.

    I don't know a lot about the hardware, but this is what lspci shows:

    I suspect I have a driver issue. The Additional Drivers tab in Software and Updates does not show a proprietary driver available.

    I have no idea if I had the issues with stock Windows because I went straight to a dedicated Ubuntu install.

    It only affects the built in touch screen. The external monitor is fine via the USB C port.

    Looking for any tips on things I can try.

    Thanks!
