    Question ASUS Transformer Book T101HA-GR029T - Webcam not working

    Hi all,

    I've installed Ubuntu Mate Release 19.10 (64-bit, Kernel Linux 5.3.0-46-generic x86_64) on my ASUS Transformer Book (T101HA-GR029T). Almost everything works out of the box. The only thing not working is the webcam. It would be very nice if that would work as well. I try to post the relevant information about my system below (let me know if something else is required):

    It might be that the device is not PCI nor USB ... I suspect I2C - but I do not know.

    Any help what I might do to make this working would be highly appreciated (I would even try to build a patched kernel).

    thanks and kind regards,
    Patrik

    Sorry, bad news.

    Like what happens with many others crappy "bay trail"/"cherry tail" based hardware, some devices, namely the webcam, are not supported. Whether they will be or not in the future only time will tell.

    This kernel will not be in 20.04 unless you manually install it. Perhaps in 20.10?

    Linux Kernel 5.7 finally fixes some Bay Trail & Cherry Trail issues

    Thank you both for your reply ... bad luck indeed - but there seems to be hope according to oldfred - I'm quite new to those things - but I like the OS already; why not to try to compile my own kernel - will at least give it a try .

    You do not have to compile it, but use a ppa to download it for Ubuntu.
    You still may have issues as part of creating a distribution is making sure every application works and or has to be recompiled to work with newer kernel.

    Never tried to change kernel.

    Re: ASUS Transformer Book T101HA-GR029T - Webcam not working

    I was able to upgrade the kernel to 5.7.0-RC1 and the device still boots - the touchscreen is a bit messed up - but nothing I could not fix with xinput & randr; unfortunately the camera still does not work. I will go back to the supported kernel to be on the safe side. So I assume I have to live with the broken camera.

    Many thanks for your help - much appreciated!

    Which applications have you used for testing the camera?

    Hi mrgs,

    I've used "Cheese" to check if the camera was recognized. Is there another application that I should try?

    kind regards,
    Patrik

    I tried guvcview on kernel 5.3.0-46 & 5.7.0-RC1; unfortunately with both kernels the application does not start. It displays a message box "Gucview error - no video device found". Does not sound promising .
