Headphone Jack Audio Issues

If the Headphone Jack Audio not working it can be fixed by create the following file:

/etc/modprobe.d/headphonejack.conf

options snd_hda_intel model=headset-mode-no-hp-mic

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-keyboard^AUR is installed this is not necessary.

acpi_os_name=Linux acpi_osi= acpi_backlight=vendor

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

Warning: Unfortunately there are problems with Comet Lake U CPUs and Undervolting. It may happen that the system "freezes" with activated 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 -0mV 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.
