Post update issue when waking up from screen off (2 monitors). Primary monitor doesn’t wake, have to power cycle monitor.
Ryzen 7 3700X
Radeon VII
video-linux
5.8.3-2
Thank you @Fabby
Sorry I forgot to add that, I added a note above:
“My desktop is KDE since the installation of this system”.
I never run two DE in my system, maybe some “tweak or app” installed in the beginning “confuses” the system 
So, the best thing is to back up the current one and leave only the pacnew in its place as you recommend?
I wish I could prevent the worst, but right now I can’t even connect a usb because it doesn’t recognize them until I reboot the system.
Regards
Solved.
After using *sudo pacdiff, I managed to find and get rid of all those old .pacnew files, then I reboot my system and after a few distressing seconds with the black screen this start with the login screen.
And I see that those new lines that refer to gnome appeared for the first time during this or the previous update.
I also found that some previous update, wreaked havoc on the shadow file; no wonder many people have complained that they cannot enter with their passwords, that new “/etc/shadow.pacnew” comes only with the “root” account:
root:*:14871::::::

All good on two machines, no problem.
Update is done, without reboot, but if I try to downgrade the packages this is the terminal-output.
]$ export LANG=C; sudo pacman -U h’***s://archive.archlinux.org/packages/p/pam/pam-1.3.1-2-x86_64.pkg.tar.xz h’***s://archive.archlinux.org/packages/p/pambase/pambase-20190105.1-2-any.pkg.tar.xz
loading packages…
error: ‘/var/cache/pacman/pkg/pam-1.3.1-2-x86_64.pkg.tar.xz’: package missing required signature
error: ‘/var/cache/pacman/pkg/pambase-20190105.1-2-any.pkg.tar.xz’: package missing required signature
How can I downgrade the packages?
Second Problem with this Update
This is the output of the terminl,. But I still not understand, what I have to do with “/etc/pam.d/system-auth”. And what does ‘merge’ means in this context?

If we do it regularly after each update we usually have 0…2 files to merge

these files in /etc exists in .conf and .conf.pacnew
*** DO NO CHANGES FOR gshadow /shadow you will destroy your Linux & login ***
see for example
sudo diff -y /etc/bumblebee/bumblebee.conf /etc/bumblebee/bumblebee.conf.pacnew

Got no pacnew concerning pam and pambase after update. Smooth update again!
Thanks Manjaro Team

I use the same laptop. When using optimus manager for GPU management, I have a bunch of issues in KDE with the 450 driver. How do you find the Nvidia 450 driver? Do you have any issues after suspend and/or with external screens? What do you use for GPU switching?
I am on bios 1.30, and the update did not affect fans in any way btw for me. It must be a bios update (which I am reluctant to do myself, due to Lenovo’s history with updates for this machine).
I’m on bios 1.34. With Nvidia 450, I don’t use switching anymore. Right now I just use the default hybrid driver by Manjaro without any changes. The external monitor works via reverse prime, I think. The only issue I got is Desktop effects have been suspended by another application. But I’ve managed to find a fix to it. If you have the same issue, you can refer to that post.

all good here
thanks for the hard work
You should open a separate topic for this as the answer is becoming more complex and I can’t find your previous responses in this huge litany of issues. @Fabby me in your new topic and put all of the data in your new question.

Erm, this shows a lot of package differences for your system going beyond the limited scope in this thread. I advise you to open a new topic for that and give some more information, because the person that knows his/her system best is you!.
Don’t always move to the newest nVidia driver immediately. if the 440 series is working for you and you’ve got no bugs, always wait until the second release (at a minimum) before trying it out. If it doesn’t work for you, revert back.
E.G. There are still open bugs with CUDA on the 450 series…
Noticed something new today: no matter how full/empty ma battery is, KDE tells me “0:28 until full/empty” in the battery info (system tray dropdown).
KDE Plasma version 5.19.4 - it didn’t behave like this before.
Cool. I did have a related issue where the compositor would just crash and not come back.
How well does the reverse prime thing work for you? Does it need the external screen to have the same resolution as the internal?
The reverse prime works well for me, as my use case is pretty simple. I use a portable monitor with the same resolution (4K) and same fraction rate (200%).
I think the external monitor may not need to be the same resolution but has to use the same fraction rate. Any additional xrandr operations for the external monitor (such as rotation) won’t work.
Still significantly higher CPU cores temperatures (5-10C when idling) since the previous update. A year ago or so an update of kernel 5 made the temperatures higher, so I switched back to 4.19. After the previous update the temperatures are elevated on 4.19 too by about 5-10C (was 37-39C, now is 44-47C). My CPU is i7-8750H, laptop Acer Aspire A717-72G. Besides this since previous update Urban Terror game cannot be played anymore (on internal CPU graphics). Only black screen appears and log shows that xfwm4 crashes when game starts. (I use the xfce DE).
hello, i get these errors when I updated now. The kernel 5.8 boots but the screen is dark(!)Skärmbild från 2020-08-31 15-18-24|690x388
