    Recently I received my beautiful new CF31-13111CM, courtesy ebay sniping. Upon installing the latest long term support (LTS) version of Ubuntu Linux, there were a few issues to resolve.

    Works out of the box:
    Keyboard
    Sound (including Fn-keys)
    CD/DVD Drive
    SD card
    Bluetooth
    Wifi
    USB
    Suspend
    CPU fan

    Detected but not tested:
    WWAN
    Fingerprint sensor

    Works after some modifications:

    Screen brightness
    1. Upgrade the bios (download the file from http://business.panasonic.com/support-computerstablets-downloads-searchdownloads . I updated it using windows and you should too).
    2. Update the operating system to at least version 15.04: the intel drivers have compatibility issues with the current LTS version.
    3. Install the intel drivers: https://01.org/linuxgraphics
    4. pass the kernel parameter acpi_backlight=native acpi_osi=

    Touchpad
    1. pass the kernel parameter i8042.nomux=1 i8042.noloop=1
    Touchscreen
    1. run xinput_calibrator (you may need to delete any config you currently have in /etc/X11/xorg.conf.d/99-calibration.conf)
    2. paste the output into /etc/X11/xorg.conf.d/99-calibration.conf and restart X

    Not tested:
    Dock
    HDMI
    Serial Port
    Antenna
    Headphones
    Mic
    EX card / PC card

    This is great piece of hardware. Thanks to Sadlmkr for his help.

    No problem, they are always changing how this is done. Now the standard is to edit /etc/default/grub

    Before:
    ...
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""
    ...    ​

    After:
    ...
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX="i8042.nomux=1 i8042.noloop=1 acpi_backlight=native acpi_osi="
    ...    ​

    no loop backlight????

    Jeff, would that cure the flicker issue you had?
    I really know nothing, but the command sounded similar..

    I will go back to windows 7 now..

    1. What brand touch pad is the MK5 sporting?

    The issue with the Interlink Versapad on CF-31MK2 ....IN LINUX....I discovered could be cleared with notimeout and nomux. The Versapad was throwing two objectional codes during boot. Causing timeout and shut down. (I may have it backwards as to who was throwing at whom.) Is why 18042.notimeout i8042.nomux worked. Just saying.

    Light reading below:

    i8042.debug [HW] Toggle i8042 debug mode
    i8042.unmask_kbd_data
    [HW] Enable printing of interrupt data from the KBD port
    (disabled by default, and as a pre-condition
    requires that i8042.debug=1 be enabled)
    i8042.direct [HW] Put keyboard port into non-translated mode
    i8042.dumbkbd [HW] Pretend that controller can only read data from
    keyboard and cannot control its state
    (Don't attempt to blink the leds)
    i8042.noaux [HW] Don't check for auxiliary (== mouse) port
    i8042.nokbd [HW] Don't check/create keyboard port
    i8042.noloop [HW] Disable the AUX Loopback command while probing
    for the AUX port
    i8042.nomux [HW] Don't check presence of an active multiplexing
    controller
    i8042.nopnp [HW] Don't use ACPIPnP / PnPBIOS to discover KBD/AUX
    controllers
    i8042.notimeout [HW] Ignore timeout condition signalled by controller
    i8042.reset [HW] Reset the controller during init and cleanup
    i8042.unlock [HW] Unlock (ignore) the keylock
    i8042.kbdreset [HW] Reset device connected to KBD port

    I use FUSE-ExFAT to read and write to my 64GB SDHC on my CF-31J. Works like a champ!
