So I noticed that neither my brightness keys (f3, f4) nor my volume keys (f9-f11) work. Every other key seems to work, though.
Also if I attempt to install something from pamac, it gives me an “authentication failed” -message without asking for password or anything, didn’t find any help for that on the internet.
Also I can’t auto-complete results in terminal for pacman -S applications. Previously if I typed in “pacman -S spo” and pressed tab, it would have given me the names of different spotify apps and if I recall correctly, even filled them in automatically. Now it doesn’t do anything. This might be a clue for what’s wrong, and I’d like it fixed, too.
I installed my Linux as Manjaro XFCE, but I use AwesomeWM, so I don’t know if my Manjaro still counts as an XFCE or not. If it’s any help, this is a laptop with an AMD cpu and gpu, which is probably integrated, and I believe my brightness software is xbacklight because that’s what I can change my brightness with in terminal.
I’ve tried to troubleshoot the brightness by going to /etc/default/grub and I’ve changed the
GRUB_CMDLINE_LINUX_DEFAULT to acpi_backlight=vendor.
I am pretty certain I’ve only added the acpi_backlight setting, others were there by default:
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
What’s the output of:
ls /sys/class/backlight/
P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU you have, …
In the future, when providing code/output, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text so that the output looks like this:

instead of like this:

(as that makes both our lives much easier)
No need to do anything right now as I’m an editor here on this site and have fixed it for you already. However, in the future I might not see your post so review my edits by pushing the orange pencil above the post I just fixed.
You’re probably confused as pacman would not give you spotify, as it is not provided in Manjaro repos (but there are many spotify related packages in the AUR). However, what you seek is bash-completion package to auto complete commands in bash shell. It adds support for pacman apparently.
OK, then I cannot help you any further as you seem to have a keyboard definition problem and I’m not running XFCE. (KDE here)
While waiting for an XFCE expert to tell you how to change the keyboard hardware layout on XFCE, you can use the above command to change the brightness:
255: maximum
0: off (don’t try this one or you’ll have a black screen and need to type blind!)
Somewhere in the middle should be good, depending on your environmental conditions.
Note: In KDE, changing the keyboard hardware is done by going to System Settings→keyboard→Keyboard Model
I have now installed the package zsh-completions but I still can’t find aur packages nor official packages by pressing tab. Instead it just lists the directories or files in my computer.
Here’s a screenshot:

(I can’t link nor can I add media items to my text, this is really counter-productive)
The wanted behaviour would be that pressing tab after typing “pacman -S s” it would list installable packages that start with the letter s.
If you search for a package name, use pacman -Ss then some letters within the package name pacman -S s
just one letter is a little too short for effective autocompletion, but I have no idea how the completion is implemented
But I used to be able to search for packages by just typing in “pacman -S (start of the package name I’m looking for, like ‘chro’, if I’m searching for chromium)”: “pacman -S chro”, and it would list out all the packages starting with chro just like it lists out files normally.
It was so much simpler and easier to follow like that instead of typing in “pacman -Ss chro”, because it lists out a huge, non-responsive list from which I can’t find anything I’m looking for: (ss: imgur . com/iCEtSL9.png), compared to the previous functionality (imgur . com/0yzO4ks.png), example shows directories/files because obviously it doesn’t work anymore
How did it work before? I tried messing around with some theming and such and might have touched the zsh configs but I don’t know what I’ve changed so that the autocompletion doesn’t work for the packages anymore.
If that worked and now it doesn’t it could be because of your shell.
Perhaps you used to use Bash
and now you are using zsh. If that’s the case and the reason …
Shell can be changed easily: chsh -u
Welcome to Manjaro! 
(reboot might be required…)
