Brightness for 120 Hz and 144 Hz displays

The brightness of displays with 120 Hz and 144 Hz can be individually adjusted thanks to a short command. By default it is not necessary to execute this command. However, if your display does not have a brightness control, you can do the following.

Variant 1: TUXEDO Installations

It is easiest for devices with TUXEDO installation (ex works or via WebFAI). Open a terminal window, simply via the start menu or Ctrl + Alt + T. There you insert the following command:

sudo sed -i s/'acpi_backlight=vendor'/'i915.enable_dpcd_backlight'/ /etc/default/grubAfter that, automatically regenerate the bootloader settings:

sudo update-grub

Finally, please restart the notebook.

Alternatively, you can combine all three steps:

sudo sed -i s/'acpi_backlight=vendor'/'i915.enable_dpcd_backlight'/ /etc/default/grub && sudo update-grub && sudo reboot

 

Variant 2: Custom Installations

If you have installed your Linux system yourself, please proceed as follows. Open a terminal window, simply via the start menu or Ctrl + Alt + T. Now open an editor with root rights and edit the file /etc/default/grub:

sudo nano /etc/default/grubThe line beginning with GRUB_CMDLINE_LINUX_DEFAULT must look as follows:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi= acpi_os_name=Linux i915.enable_dpcd_backlight"You must therefore add the following to the line:

acpi_osi= acpi_os_name=Linux i915.enable_dpcd_backlightSave your changes with Ctrl + O and exit the editor with Ctrl + X.

Then generate the bootloader and restart the device:

sudo update-grub
sudo reboot

Contact

We are personally there for you Monday to Friday from 9 am to 1 pm and from 2 pm to 5 pm (German time). But also outside these times you can contact our team with your request by e-mail. Please include your customer number, the model name of your laptop or PC and as detailed a description of your request as possible. The more details you give us, the faster we can process your request!

We might not be able to answer questions about third party hardware or software. For questions about popular open source software (Thunderbird, Filezilla...) please contact a forum e.g. ubuntuforums.org. The research effort for application specific setup is immense and not manageable at the current time. Basic compatibility questions e.g. are of course still welcome!

For orders outside the EU there might be additional duties, taxes or charges needed to be paid by the customer. These don't have to be paid to the supplier, but to local authorities. Please check for any details with your local customs or tax authorities before ordering! But as a benefit you don't have to pay German taxes, this means you save up to 19%!
Due to the Brexit and the associated changes, there may be delays of several days in customs clearance on site for deliveries to the UK. This is not within our sphere of influence, so we ask for your understanding.
