    Walkthrought installing Ubuntu on T100HA

    Hi all, I created new thread specifically oriented around Ubuntu and T100HA

    This is the news from my investigations for Ubuntu on T100HA.
    To remember, it is ubuntu 17.04 alpha 2 from Linuxium.

    • Wifi: Working out of the box.
    • Touchscreen: Working out of the box. Need to add a command to modify screen orientation.
    • Sound: Working out of the box.
    • SD card reader: Not yet tested
    • Battery monitoring: Working out of the box.
    • Tablet keys: Not yet working
    • Power management: Not yet working
    • Orientation sensor: Not yet working
    • Backlight & ambient light sensor: Not yet working
    • Touchpad: Working out of the box without multi-touch
    • Camera: Not yet tested but probably not working.
    • Bluetooth: Not yet tested.


    Screen Orientation:
    To put orientation every time in landscape mode, you can add file /usr/share/X11/xorg.conf.d/10-monitor.conf with the code below.
    Code:
    Section "Device"
    Identifier "Configured Video Device"
    Driver "fbdev"
    Option "UseFBDev" "true"
    Option "Rotate" "CCW"
    EndSection
    
    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "800x1280"
    EndSubSection
    EndSection
    Personnaly, I removed this file because with this file, it isn't possible to change manually the orientation of the screen. Inconvenient, the login screen is in portrait mode.

    Touchscreen:
    Touch screen orientation is ok with the command
    Code:
    xinput set-prop 'SIS0457:00 0457:113D' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
    in startup applications. Use the command below to know your device ID.
    Code:
    xinput list
    Docking:
    When my tablet is undocked or docked, the onboard keyboard appears and disappears with the scripts from Latest steps to install Ubuntu on the Asus T100TA | John Wells
    You must add ./ before docked.sh and undocked.sh.
    This solution does not work perfectly and I think can be optimized.

    Brightness:
    To change the brightness (it is not really brightness but gamma), you can use the commands below. The syntax is:
    Code:
    xrandr --output <OUTPUT> --brightness <VALUE>
    where the <OUTPUT> can be found with:
    Code:
    xrandr | grep -w connected | cut -d" " -f1
    and the <VALUE> should be something between 0 and 1. For example:
    Code:
    xrandr --output DSI-1 --brightness 0.8
    Under 0.5, it is not really usable due to the grey filter on the screen.

    I will update this post regarding solutions

    Great initiative creating a thread for this subject... Ubuntu for me feels a bit easier to manage than other Linux flavors and I was beginning to feel a bit lost in the "...other OS's"-thread,

    May I ask if you're using the Lubuntu or the Unity iso?

    Hi,

    News from my investigation, I can now manage the brigthness. I found the solution from https://wiki.debian.org/InstallingDebianOn/Asus/T100TA. I updated the first post with explaination.

    I agree with you for the other thread. I use the Unity version but I think it is available for Lubuntu version.
    I tested a lot off version, Debian's and Ubuntu's but only this Linuxium 17.04 version works so...

    Hello everybody, thank you for the report, I've been following this forum for months waiting for good news!
    Have just used my T100HA with Ubuntu 17.04 pseudo-beta1 from Linuxium (2017-03-11) while listening some music on YouTube, and worked decently until I've had the great idea to undock it, thus forcefully detaching the live USB stick...
    However, updating what said in the first post:
    - Micro-SD reader: works out of the box.
    - Sound: works out of the box once you select "speakers" as output device. "Analog Output" is the default but does not work (players hang).
    - Battery life is poor: from 26% to 14% in half an hour, with "brightness" set to 0.8.
    - Camera: not detected.
    - Bluetooth: detected (and disabled to spare battery), but not tested.
    - Touch screen: no gestures, and I confirm the portrait-only orientation out of the box.
    - Everything else confirmed.
    We are almost there!
