X.org works flawlessly with version 2:2.99.917-1 of Intel video drivers.

With standard Jessie kernel (Linux 3.16), the {{{nomodeset}}} option is required to get X server displaying things. And in this case the DRI is software emulated, resulting in poor performances, such as no fluid full screen video playing. You get hardware DRI with kernel Linux 4.0 and corresponding Intel drivers.

To get the kernel Linux in version 4.0 starting from a standard Jessie, you need to set some APT preferences :
{{{
Package: *
Pin: release a=stable
Pin-Priority: 700

Package: *
Pin: release a=jessie-backports
Pin-Priority: 660

Package: *
Pin: release a=unstable
Pin-Priority: 90
}}}

And edit {{{ /etc/apt/sources.list }}} to add :
{{{
# jessie-backports
deb http://ftp.us.debian.org/debian/ jessie-backports main contrib non-free
deb-src http://ftp.us.debian.org/debian/ jessie-backports main contrib non-free

# Sid unstable
deb http://ftp.us.debian.org/debian/ unstable main contrib non-free
deb-src http://ftp.us.debian.org/debian/ unstable main contrib non-free
}}}

As explained here : https://www.linuxquestions.org/questions/debian-26/kernel-backport-for-debian-jessie-4175542797/#post5364663

=== Hardware acceleration ===
==== VLC ====

Then, to get hardware coding in VLC, open the preferences dialog :
 * select "video output GLX XCB" in the Video tab ;
 * and "VA API via DRM" in the Codec tab.

==== Flash ====

As explained here : https://askubuntu.com/questions/500911/ubuntu-14-04-not-recognizing-installed-intel-graphics-driver

You can get in-Iceweasel flashplayer to be hardware accelerated, and so being able to stretch video into full screen mode. First, install {{{libvdpau-va-gl1}}} version 0.3.4-2 : {{{ sudo apt-get install libvdpau-va-gl1 }}}

Then create a file /etc/adobe/mms.conf :
{{{
sudo mkdir -p /etc/adobe
echo "EnableLinuxHWVideoDecode=1" | sudo tee /etc/adobe/mms.cfg
echo "OverrideGPUValidation=1" | sudo tee -a /etc/adobe/mms.cfg
}}}

Then, add : {{{ export VDPAU_DRIVER=va_gl }}} ; to your {{{/usr/bin/firefox}}} shell script file. Restart Iceweasel, you'll get full screen video.

=== HiDPI ===

The UX360UA screen is 293x165 mm, for a resolution of 3200x1800px, which represents a high dot-per-inch value as of 2015. In consequence, all writings are very small on the screen as long as you set some parameters.

==== XFCE ====

Using XFCE, you'll be able to set a DPI value in the Appearance settings, tab Police. Values upper than 125 are workable, and 147 is recommended.

Nevertheless I also recommend to activated anti-aliasing of the fonts, and Inconsolata as xfce4-terminal font (from {{{ fonts-inconsolata }}} Debian package).

==== QT based applications ====

QT based applications should accept the {{{ -style gtk }}} parameter, when started from command line interface. This tells QT-based applications to follow the look-and-feel of GTK based application. As XFCE is GTK based, XFCE settings will apply (tested with FreeCAD and GridcoinResearch wallet).

==== Iceweasel / Firefox-esr ====

Iceweasel 31 can't take advantage of this setting. To comfortably use it, you may open the about:config tab and set : {{{ layout.css.devPixelsPerPx=1.75 }}}

It exists a AutoHiDPI Firefox module which automatically switches between a HiDPI value of {{{ layout.css.devPixelsPerPx= }}} and LoDPI value, based on one breaking point configurable value, sets to 2880px by default : https://addons.mozilla.org/en-US/firefox/addon/autohidpi/?src=api (but it's not working well as of late 2015, clumsily changing screen DPI if a small window is popped up for instance).

It also exists a {{{ layout.css.dpi= }}} parameter : http://kb.mozillazine.org/Layout.css.dpi (not tried)

Another solution is to use Iceweasel module Zoom Page, which automatically zooms to optimal width, removing margins : https://addons.mozilla.org/en-US/firefox/addon/zoom-page/

And to finish, I use NoiaScrollbars addon, to configure different size and colors for scrollbars (which are else too small to be seen with a dark background) : https://addons.mozilla.org/en-US/firefox/addon/noiascrollbars/

==== gkrellm ====

You can set specific fonts and sizes in gkrellm, but also play with a zoom factor in Configuration, Themes, tab Options, Scale setting on the bottom of the tab. A value of 200% is a working setting.

==== VLC ====

Unfortunately, VLC don't seems to offer a way to tweak its font sizes.

## If this computer has variants with various Display adapter, simply
## duplicate this section, like "Display / Ati".

== Audio ==
## First say what's the Sound adapter model (lspci may help)
## Then explain how to get it working
Works out of the box, even function keys, but the mute key mutes Master and Speaker channels while unmute only unmutes Master…

== Touchpad ==
Works out of the box. Tap-clicks (single, double for right click, triple for middle) can be setup through XFCE mouse parameters.
Feels much better than HP Folio¹³ one's.

Hotkey F9 is not disabling it.

'''UX305C''' : As stated in ArchLinux [[https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX305|wiki]], touchpad also needs a kernel Linux 4.5.0-rc1 or later to work with Debian.

== Power Management ==
## Have you tested Hibernation and/or
## Then explain how to get it working

=== Sleep and hibernate ===

Sleep and Hibernate both do work without problems.

=== Screen backlight ===
Screen backlight control needs Linux 4.0 (currently from unstable) to work, through power management icon' slider.
 
Screen backlight extinction hotkey is working, but not the mode-auto one with logo (fn+A with qwerty keyboard, fn+Q with azerty one).

The increase / decrease keys do exist, but they are not F5 and F6 as the physical keyboard would let you guess, but rather F3 and F4. This can be discerned with {{{ xev }}}, but cannot be used by XFCE keyboard settings tool (which is able to select those keys but won't trigger any action when pressed).

To adjust screen backlight from keyboard shortcuts, I use `xbacklight` with the following binding :
  * xbacklight -inc 10 -> Super + F6
  * xbacklight -dec 10 -> Super + F5


=== Power consumption measures ===

Information gathered with {{{ powertop }}}, on battery discharging.
Three scenarios with wifi on and bluetooth off :
  * Intensive usage (Backlight 100%, CPU 50%) : 12W - 4h of autonomy
  * Medium usage (Backlight 50%, CPU <10%) : 7W - 6h of autonomy
  * No usage (Backlight 0%, CPU <1%) : 3,4W - 12h of autonomy

=== Hardware battery saving mode = CPU at 500MHz ===

When battery level becomes under 10%, the CPU slows down under 800MHz to reach, according to gkrellm2 measures : 500MHz and stays at this slowness.

It can helps when watching a movie on battery, as {{{VLC}}} has all the chances to stop decoding images on time in fullscreen mode with only 500MHz of CPU, hence warning you to plug the laptop.

'''UX305C''' : The scaling frequency range of Intel 6Y75 CPU is 400MHz - 3100MHz, which means that the CPU is falling to 400MHz when idle with no further configuration needed.

== WiFi ==

Needs {{{firmware-iwlwifi}}} and {{{fimware-linux-nonfree}}} 0.44 to work with kernel Linux 4.0.
Plane mode hotkey (F2) effectively cuts it even if key's built-in light is lighting or not.

== Bluetooth ==

Install Blueman to get control over Bluetooth functionalities through an icon : {{{ sudo apt-get install blueman }}}

Surprisingly, the plane mode hotkey (F2) is unable to hide the peripheral once it has been set to be visible during one minute, despite the deactivated bluetooth icon.
