Fix flickering display after manually installing an OS

If you install an operating system manually (not through FAI) on your InfinityBook Pro 14 Gen6 (only 3K-Omnia-Variant!), you might experience display flickering afterwards. To fix this, you must add a parameter to the configuration of the boot manager GRUB. 

To achieve this, open the file /etc/default/grub with an editor of your choice. The command to do this with the editor Nano looks like this:

sudo nano /etc/default/grub

Search there in the upper area for the line beginning with 

GRUB_CMDLINE_LINUX_DEFAULT=

The parameters in quotation marks may differ depending on the distribution you use, and are not relevant here. Within the quotes and separated by a space, you must now enter the parameter:

i915.enable_psr=0

This could look something like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.enable_psr=0"
Thereafter, save the change in the editor and close it. Finally, you have to update GRUB by issuing the following command in the terminal:

sudo update-grub

This completes the change, and a reboot should hopefully produce a display without flickering. You can check if the parameter was taken correctly by checking the kernel command line (cmdline) in the terminal:

cat /proc/cmdline

In the output, the parameter should be displayed at the end.

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.
