Depending on the device you are using this might be a known issue - e.g. for the Pinebook Pro we already addressed this one with the author of the original patch.
Yes there is a regression in linux 5.8 usb-c patch I noticed it today when I tried to connect my pbp to my screen.
Might have to look into this soon.

Let me know if I can support you here.
I apologize for my vague post. I had 2 different Manjaro forums windows open. I have a pinebook pro with the factory Manjaro kde installed. Everything has been fine with the usb-c to hdmi adapter for several months. I recently updated the kernel and some other packages, but after reboot, there is no video out. If this has already been addressed, please point me in the right direction as I spent almost all day searching for a solution to no avail.
Please keep in mind I am not a pro Linux user. I purchased the pinephone and pinebook pro to support the communities and learn.
Thank you all for your help.
It’s a known issue. The patch we used in 5.7 kernel, does no longer work in 5.8. We have mentioned it to the patch maintainer, so all we can do is wait until it’s fixed.
@strit @appelgriebsch @spikerguy Thank you all for taking the time to read my post. I really appreciate all the hard work the developers have put into Manjaro. I will wait patiently as I am confident the issue will get resolved.
Thanks
USB C video out on the Pinebook Pro stopped working after the 5.8 kernel update.
The VIA USB billboard device shows up but Displayport never connects.
Read the posts above you. It’s a known issue.

Edit: i see others are having the same issue. I use external display every day. Please fix it
Hi,
I’m using a pinebook pro with KDE Plasma. I had linux-aarch64 5.7 before the update. After the update i have linux 5.8 now.
The external display is not working anymore. DP-Alt mode.
I had no issues with the external display bevor kernel linux 5.8.
Is this a known issue ? I haven’t seen any infos about it.
Thanks.
Chris
We have notified the patch maintainer. Hopefully we will get a fix for it soon.

Hello. I’m trying to avoid any problems with my pending, fat update. I’m not sure if this affects me, but considering that I can’t find the “/boot/extlinux/extlinux.conf file”, then am I good to go? Thank you.
What device is it and what version did you install from?
It is an HP laptop, multiple partition scheme, dual-boot Manjaro-Windows, uefi, and I really don’t remember what my installation version was, I have some evidence from an archived post that it could be 20.04.x, but I can’t be 100% sure (is there some way to find out?)
This thread is for ARM devices. You should post in [Stable Update] 2020-08-16 - Kernels, Plasma, KDE Framework, Systemd, Pamac, VirtualBox, Firefox.

I’m so sorry. I’m a newbie.
Hello, D-bus doesn’t start anymore. Mousepad doesn’t start anymore and LibreOffice lose the menu bar.
In 20.06 and in the update 20.08, systemd-networkd-wait-online fails to start, and network manager doesn’t start automatically. I can start network manager manually.
I think I will reinstall when the kernel patch for USB-C to HDMI will be released, it will be easier.

@regivanx I had the same network manager problem after a post-update restart. I manually started it, refreshed mirrors, and the problem did not return.
After I read that your libreoffice bar was missing, I started office and confirm mine is missing too. I will try to remove and reinstall office to see if it fixes it.
FWIW, I’m not too savvy at error logs and such as I’m still learning.
You have 2 network services trying to fight doing the same thing. This should not be enabled when using Network Manager.
sudo systemctl disable systemd-networkd
sudo systemctl disable systemd-networkd.socket
reboot
