Power management is not working properly after update. cannot change display brightness on my dell inspiron 5558 laptop. (KDE) slider moves and popup animation is shown with keyboard shortcuts but does not affect brightness at all.
(I downgraded pulseaudio and its dependency due to ongoing audio port switching issue but I don’t think this should have anything to do with brightness)
Hi, I installed the latest stable image of Manjaro KDE on the 15th on a brand new Lenovo T14 and the touchpad was working fine.
After the update the touchpad is not working anymore 
I tried to downgrade libinput but the problem remains so it might be bigger than that 
Edit: I updated to the 5.9 kernel and the issues remained. I shutdown (not restart) the computer and start again and it worked.
I think the issue came from me rebooting from windows (dual boot), I just read that sometimes the driver for hardware is loaded in the flash memory, which means it’s always recommanded to shutdown and start computer when you want to change the operation sytem used (and not reboot).
So I don’t think my problem was coming from the update (just a bad coincidence). I leave my experience here, just so it can help.
There is solution posted already
OK, I’ve dug into the OpenVPN problems and I’ve found the solution.
The main problem is that the new systemd unit specifies running as user openvpn and group network, whereas the original (pretty sure I didn’t change it, though I may be wrong) didn’t specify a user/group.
So the big problem was the daemon not being able to read config in /etc/openvpn. The solution here is to change the ownership of that directory (and everything under it) to openvpn.
A secondary problem (for me) was that I was specifying AES-256-CBC as the cypher, and this is no longer supported. Changing that to AES-256-GCM fixed the problem (this was also set as one of the alternative options in my client device’s config, so this was safe for me. This may not be the case for everyone).
You cloud also add
data-ciphers AES-256-GCM:AES-128-GCM:AES-256-CBC
to the client config.
It is stated in OpenVPN log after connection fails.
I think it would be the “more sensible way” because of the change from --ncp-ciphers to --data-ciphers.
Maybe the following works for you as well?
I am unsure about why there was no pacnew or why quite a few users, including me, somehow apparently must have missed it – the problem is the (silent?) removal of the encrypt hook.
Yes I also had issues with lightdm failing and startx failed also. So I booted to latest kernel in single user mode and followed Phil advice in original post (pamac remove command, etc.). Then I had to reset mirrorlist and make sure downloading OK. Also had to boot into latest kernel and CTRL+ALT+F2 and finish off driver install: Trying to update to nvidia-450xx
Updated on GIGABYTE AORUS B550I, Kernel 5.9.8, KDE
Not updated 2nd PC with GIGABYTE X370 Gaming 5 (also no sound).
Very bad quality - it´s enough!!
Maybe you added fsck to HOOKS in /etc/mkinitcpio.conf ?
I don’t even know what does that file do. I never touched it.
Does anyone know?
Please look above, in my two systems it is not fixed. 
No nvidia 418.xx drivers for Linux 5.9?
If a “pacman -Qi startup-notification” in the terminal says there is no 'required by" packages, you can remove it.
But using “sudo pacman -Rns startup-notification” will show you the dependencies too and you have the option to remove it or not.
Hardware accelerated video decode no longer works in Chromium with kernel 5.9.8.
I don’t think there was a removal of anything, as Manjaro update a pacnew file without touching your user config file. Maybe you as others have a helper tool which do auto merging of .pacnew (which is a bad idea IMO)?
Nope, currently you have 390 for legacy cards, or 450 and 455 see here Manjaro - Branch Compare
LTS 5.4 kernel has all of them though 
(340, 390, 418, 430, 435, 440, 450, 455)
nothing to do with Manjaro or kernel, it’s a Pulseaudio regression, you may try to downgrade Pulseaudio for the moment
may be fixed on Pulseaudio 14 I guess, you may try to do as suggest above…
