Installation

Installation was uneventful. It is a normal EFI installation.

Configuration

Video

Drivers

See Intel Graphics and Hardware Acceleration

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-keyboard^AUR 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-keyboard^AUR

TUXEDO Control Center

TUXEDO Computers provides their own control center, TUXEDO Control Center (TCC), "to help you control performance, energy, fan and comfort settings". Install the tuxedo-control-center-bin^AUR package.

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

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.
