Dell Laptop Some FN Keys not working with MX21

[razor2021]

Great job @Huckleberry Finn - would have never thought a new install would have user settings that can cause laptop keys to misbehave. Good job persisting to figure it out @Fornhamfred . Like a terrier biting on an ankle.

Thanks to you both. Happy New Year

Oh la la :D

A real puzzle. Anyway, glad it works now and thank you for the feedback.

If you like, this will be a perfect experiment (and nothing to lose): You can copy your actual user's settings to the new one with MX User Manager - "Copy/Sync" tab (and also see if it breaks that, too ) :)

Yes broke the new user account

Then if you like only, you can create a new user again and first see if it works again,

then copy 1-2 "dot" folders each time manually from here to there (and reboot and login with new user) and narrow down to find the culprit.

Since it requires 5-10 boots it may be tiresome but no need to hurry.

It'll be a very good feedback to developers in case you find/approach the culprit.

Sorry slight misinformation.

Tried the copy of home to new user again having deleted the first try. When copying between desktops first time round I selected copy only. The second time I chose sync ( which I now realise is copy and sync ) and did not break the user all fn keys working fine. Perhaps the option in user manager should copy only or copy and sync. Just a suggestion.

As you might've already thought: You can delete the original user, then rename the new user to the original one (just in case you want that username). The only difference will be that the 1st user's id was 1000 , now it'll probably be 1002 ... that won't make any harm :)

(Though it's still a mystery what causes that)

Update:

After some time I decided to try again. Totally unrelated I found a pulse audio plugin on add items to panels. Having added this the fn keys for volume control work perfectly. I have noticed that there is a newer version of pulseaudio in the test repro and wonder if it is worth updating that and then checking if the fn keys still work?

You may/may not .. if you like, you can install that, try, and remove if it's unsuccessful (then re-install the stable one).
Also you can save your home folder to somewhere else, furthermore take a snapshot beforehand :)
