    Re: Ubuntu and the asus zenbook (UX31)

    Looks like Asus does not sell UX31e in the UK. Only model of Zenbook I can find is UX31A with 24gb SSD and 500Gb SATA. I do not mind UX32A but I need 128/256gb SSD and no SATA, but it is not available in the UK either

    2) Download the kernel sources from kernel.org and unzip them ; then go in the kernel sources folder


    3) Download the patches and apply them (https://patchwork.kernel.org/patch/2696121/raw/ and https://patchwork.kernel.org/patch/2718041/raw/)
    patch -p1 < PATCH_TO_APPLY


    4) Configure the kernel (be sure everything you use is plugged or some modules may be missing - in my case, I didn't plug my USB key and now it doesn't work) ; if asked anything you don't understand, press "enter" to keep the default value
    cp -vi /boot/config-`uname -r` .config
    yes "" | make oldconfig
    yes "" | make localmodconfig
    ./scripts/config --file .config -d ATH9K_RATE_CONTROL


    5) Compile
    make -j5


    6) Install
    sudo make modules_install
    sudo make install


    7) If you want to remove the kernel later on you have to remove :
    /boot/vmlinuz*KERNEL-VERSION*
    /boot/initrd*KERNEL-VERSION*
    /boot/System-map*KERNEL-VERSION*
    /boot/config-*KERNEL-VERSION*
    /lib/modules/*KERNEL-VERSION*/
    then do :
    sudo update-grub
    Thank you, it worked perfectly!

    Re: Ubuntu and the asus zenbook (UX31)

    With the patches i got WAY better wifi performance.

    Just a little (different and simpler) tutorial for kernel compilation from me:

    1) Install needed packages:
    Code:
    sudo apt-get install build-essential kernel-package fakeroot libncurses5-dev git iasl
    2) Download kernel-sources from kernel.org, unzip them and go into the kernel directory:
    https://www.kernel.org/ --> I've took 3.9.6 stable


    3) Download the two patches and apply them https://patchwork.kernel.org/patch/2696121/raw/ , https://patchwork.kernel.org/patch/2718041/raw/
    Code:
    patch -p1 < PATCH_TO_APPLY



    4) Copy your actual kernel config and rebuild it (just exit menuconfig immediately):
    Code:
    cp /boot/config-`uname -r` ./.config
    ./scripts/config --file .config -d ATH9K_RATE_CONTROL
    make menuconfig

    5) Compile

    Code:
    fakeroot make-kpkg clean
    fakeroot make-kpkg --jobs=4 --initrd --append-to-version=-NAME --revision=20130620 kernel_image kernel_headers modules_image
    6) Install the deb packages (make sure that only the kernel deb packages are in this directory)
    Code:
    cd ../
    sudo dpkg -i *.deb
    sudo update-grub



    7) If you want to remove the kernel later on, just use apt-get and at least do:
    Code:
    sudo update-grub

What I found strange is that it don't work with my Windows OS too.
    JFYI: The eduroam connectivity problems stem from Bug No. 1104476. A work-around exists, see here. I hope the problem gets fixed in 13.10, tho.

    Re: Ubuntu and the asus zenbook (UX31)

    It is possible to backport the wifi fix to your current kernel instead of compiling a new kernel :
    1) get the lateste archive here : https://www.kernel.org/pub/linux/ker...ts/2013/06/18/
    2) uncompress the archive and go in the uncompressed folder
    3) run "make defconfig-ath9k", then "make" and then "sudo make install"
    4) reboot and enjoy the patched version of the driver

    I tried both methods (applying patch on stock kernel and applying patch on latest stable kernel), but both methods did not work for me. After installing the kernel my wifi module does not seem to find any wireless networks anymore...


    EDIT: none of my modules seem to work, although I am sure that I did everything right according to the instructions. Anyone having the same problem?

    EDIT2: solved the wifi problem by just installing another kernel than the stock kernel (3.0.8-26-generic) without applying the patches. When installing kernel 3.9.x or 3.10.x, the wifi problem is solved but the brightness keys don't function properly. Both wifi and brightness keys are solved using kernel 3.8.13-03081304-generic: got a stable download speed of 64mbit/s with brightness keys functioning as they should.

    So far so good using this method. Thanks for the instructions!

    I have to admit, I don't really understand what this does. When a new kernel update comes out naturally through the repos, will installing it undo this backport?

    Re: Ubuntu and the asus zenbook (UX31)

    HI,

    Just for info, I compiled the 3.9.7 version with the wifi patch and it work quite well. About battery cosumption I can reach something around less than 6W.
    No issue so far.

    if i am at all following this correctly, i have done this:

    Code:
    randy@randy-UX31E ~/Downloads/backports-20130618/defconfigs $ make defconfig-ath9kmake: *** No rule to make target `defconfig-ath9k'.  Stop.
    and getting no success.
