How to get brightness keys to work in Ubuntu 22.10 GNOME 43.1

de flag

The brightness slider in the system menu works just fine, so do all the media control keys. Airplane mode key faces the same issue but isn't as much of a bother.

I have tried multiple solutions provided elsewhere, one of them being this one.

Fixed the missing gedit issue thanks to this reply under it but an error pops up in the terminal when I follow through the saving part.

** (gedit:4416): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-spell-language not supported

The subsequent command

sudo update-initramfs -u

fetches no response from the terminal.

I ignored them and tried rebooting the system as instructed further but to no avail, the keys don't work.

Any sort of help would be appreciated.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
