After a few problems I can confirm ASUS Zenbook Prime UX31A-DH5 working with Kubuntu 13.10. Here are the steps I did:
Get kubuntu from http://www.kubuntu.org/getkubuntu/download
At the time of writing, version 13.10 was the most recent. It should work with BIOS Secure Boot option.
Copy iso image to usb device
[67675.270470] sdf: sdf1 sdf2 [67675.335259] sd 8:0:0:0: [sdf] No Caching mode page found [67675.335261] sd 8:0:0:0: [sdf] Assuming drive cache: write through [67675.335263] sd 8:0:0:0: [sdf] Attached SCSI removable disk
dd if=kubuntu-13.10-desktop-amd64.iso of=/dev/sdf
Create a partition where ubuntu will be installed. In Windows 8 under Settings -> Control Panel -> Administrative Tools -> Computer Management -> Storage -> Disk Management –> Shrink Volume
Updated bios to 219 version. Make sure you have correct model, in my case its UX31A. Go to assus support site and get the BIOS file. Copy the BIOS file onto a USB stick. Reboot and press the esc button to enter the BIOS menu. Then select “Enter Setup”. From the Advanced tab, choose the Easy Flash option and then select the BIOS file to update.
Installing from a Live USB
Reboot than press and hold ESC for boot menu. I had trouble booting from one USB key and had to use another. Eventually the USB device got recognized and I got grub2 menu. After selecting kubuntu, the screen went black!1&(^$!@(*^& I connected external monitor and viola, ubuntu was there. See this bug.
Selected manual partitions, created 4GB swap and ~33GB / ext4 partition and proceeded with install.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-update
Black screen after the 1st boot
Kernel 3.11 has a bug with intel4000
Laptop screen black due to this bug. It is fixed in kernel-3.12, however this patch is not included with Kubuntu-13.10 :(. Kernel can be updated to v 3.12 as described here:
mkdir kernel\ v3.12.2-trusty && cd kernel\ v3.12.2-trusty
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.2-trusty/linux-image-3.12.2-031202-generic_3.12.2-031202.201311291538_amd64.deb--2013-11-30 18:47:15-- http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.2-trusty/linux-image-3.12.2-031202-generic_3.12.2-031202.201311291538_amd64.deb
sudo dpkg -i linux-*.deb
sudo reboot now
My Zenbook now properly boots with laptop screen working as it is supposed to!
Some other tips for power saving optimization include modifying kernel parameters:
sudo nano -w /etc/default/grub
modify to include:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi='!Windows 2012' pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1 nmi_watchdog=0"
and update grub with
Increase the life of your SSD by reducing number of OS writes to SSD
sudo nano -w /etc/fstab
and add discard,noatime,nodiratime params to your SSD partition as well as tmpfs. noatime disable (or significantly reduce) disk writes whenever a file is read. nodiratime gives you the same functionality for directories. discard filesystem option is for automatic/online TRIM.
UUID=0d67e753-acb6-46c4-acb4-1bd4f14fe92c / ext4 discard,noatime,nodiratime,errors=remount-ro 0 1 tmpfs /tmp tmpfs defaults,discard,noatime,mode=1777 0 0
Make sure deadline is used as IO Scheduler
sudo cat /sys/block/sda/queue/scheduler
noop [deadline] cfq
Most systems with more than 2GB RAM rarely use swap space except for hibernate. Reduce usage of swap space in order to minimise number of writes to swap with
sudo echo 1 > /proc/sys/vm/swappiness
alternatively, this can be done by modifying sysctl
sudo nano -w /etc/sysctl.d/99-sysctl.conf
to look like
Current Xorg-server uses a display resolution setting of 96dpi by default. UX31E Zenbooks have a resolution of ~138dpi. The default value of 96dpi makes fonts look really small. You can list the current setting with:
Override the default value with
xrandr --dpi 138/eDP1
To keep this permanent add xrand call to /etc/X11/xinit/xinitrc
sudo nano -w /etc/X11/xinit/xinitrc
Right and middle mouse clicks are not working. This needs specific xinput instruct. A quick recipe is given here. Create an executable script:
sudo nano -w /usr/local/bin/touchpad.sh
chmod +x /usr/local/bin/touchpad.sh
and add the following code
#!/bin/bash xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics ClickPad" 1 xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Soft Button Areas" 1956 0 1737 0 1304 1955 1737 0 syndaemon -i 1.7 -d -t -K
Lastly start this script
To make it permanent add it to SystemSettings–>Startup and Shutdown–>AutoStart
