I have a Librem 15v3 with DE keyboard for review. When I run the initial setup and choose DE as keyboard language, the setting does not take. This leads to the password for wireless to fail. It took me a while to realize it was the keyboard setting that failed. Using the appropriate US characters worked fine. Skipping wireless and finishing initial setup then showed EN as the set keyboard language in the menu on top right (see attached screenshot). After switching to the German option that was available, things worked normal from there on. So German is added to the list, just not chosen as the default, even though German was ticked in the initial setup. I did this 3 times to make sure it is not a one time glitch.
