## Installation

Installation was uneventful. It's a normal EFI installation.

## Configuration

### Video

#### Drivers

See Intel Graphics and Hardware Acceleration

### Fn Function Keys

The most `Fn` function keys work out of the box. For the `Fn` function keys `F10`, `F11` and `F12` the following must be set as kernel parameter. If tuxedo-keyboardAUR is installed this is not necessary.

    acpi_os_name=Linux acpi_osi= acpi_backlight=vendor

### Keyboard Backlight

TUXEDO Computers provides a driver for their models with RGB keyboard. TUXEDO Keyboard can be installed manually from source or you use tuxedo-keyboardAUR

### TUXEDO Control Center

TUXEDO Computers provides their own Control Center named "TUXEDO Control Center" (short TCC). Install the tuxedo-control-centerAUR AUR Package.

TCC helps you to Control Fan Speed, Energy and Performance

## Power Management

### Suspend

The inefficient s2idle suspend variant is pre-selected as default. You should select the much more efficient deep variant:

     $ cat /sys/power/mem_sleep
     [s2idle] deep
     # echo deep | tee /sys/power/mem_sleep
     $ cat /sys/power/mem_sleep
     s2idle [deep]

To make this permanent add `mem_sleep_default=deep` to your kernel parameters.

An easy way is to run the following command as root:

     # sed -ie 's/GRUB_CMDLINE_LINUX_DEFAULT="\(.*\)"/GRUB_CMDLINE_LINUX_DEFAULT="\1 mem_sleep_default=deep"/' /etc/default/grub

Read more at the help page from TUXEDO [1].

### Undervolting

With the TUXEDO Premium BIOS you can undervolt the CPU over the BIOS. You can switch between `-10mV` and `-100mV`. The selectable values are not dangerous, but test it in small steps. So try `-60mV`, if it is stable you can try `-70mV` and so on You also can use intel-undervolt. Read Undervolting CPU for more Informations.
As default `-50mV` is pre-selected. You can change the value over the BIOS under Setup Utility > Advanced > Advanced Chipset Control > BIOS-controlled Undervolting.

### BIOS Performance Profiles

With the TUXEDO Premium BIOS you can select one of four Performance Profiles. As default the `Entertainment` is pre-selected.

- Quiet
- Power Saving
- Entertainment
- Performance

You can change the Profile over the BIOS under Setup Utility > Advanced > Advanced Chipset Control > Performance Profile Select.
More informations can found at the help page from TUXEDO [2]

### Thunderbolt

The integreated Thunderbolt Controller will only shown up when a Thunderbolt device is connected or if you manually force Thunderbolt power.
