[Stable Update] 2020-12-30 - Kernels, KDE, Cinnamon, LibreOffice, Python 3.9, Mesa 20.3.1

Remove both packages before you do the update.


You have to remove all modules of the old linux58 kernel with it.
In your case, try:
sudo pacman -R linux58-nvidia-430xx linux58

mhwd-kernel -r linux58

should take care of this.

Warning: config '/var/lib/mhwd/local/pci/video-nvidia-455xx/MHWDCONFIG' is invalid!
video-nvidia 2020.11.30

Perhaps I can switch to video-linux for now? And then fix things from there?

error: failed to prepare transaction (could not satisfy dependencies)
:: removing linux58-nvidia-430xx breaks dependency ‘linux58-nvidia-430xx’ required by linux-latest-nvidia-430xx
what to do now

It can be, as not all combinations are supported anymore. However for 455xx Nvidia drivers we have now these packages:

core/mhwd-nvidia 455.45.01-3
extra/linux[xxy]-nvidia 455.45.01-X
extra/nvidia-utils 455.45.01-2
extra/opencl-nvidia 455.45.01-2
multilib/lib32-nvidia-utils 455.45.01-3
multilib/lib32-opencl-nvidia 455.45.01-3

opencl is optional. manjaro-system should take care of the mhwd profiles, if it finds a valid one.

also remove the linux-latest packages with it. Try:

sudo pacman -R linux58-nvidia-430xx linux58 linux-latest-nvidia-430xx linux-latest

You can install the linux-latest metapackages after the update again if you want to use them.

The top driver should be the latest supported on your end. Also check if some packages are missing.

I’ve got this message:

Warnung: /root/.zshrc installiert als /root/.zshrc.pacnew

But /root/ is locked, so I cannot edit the /root/.zshrc. What to do?

Merge those files as root user…

You can use pacdiff to go through all the changes you may have (in regards to new configs)

After Updating, I lost the use of my touchpad (on a Thinkpad), any ideas?

(In the settings, it states that no touchpad is detected)

It’s come back after another restart. :+1:

update and 1st reboot was okay, after switching to kernel 5.10 screen remains black. no error message or else displayed.

I assume it it in relation to the nvidia drivers.

What do I do now to fix the system?

Got linux510-nvidia installed? If not, install it. I still don’t get why people use those proprietary drivers …

Well, because recent Nvidia cards are UNUSABLE with the free driver (black screens and freezes) as well as performance is way off, not letting us play any game. So we have no choice but use these proprietary drivers.


nope, checked in pacman gui and no further update was displayed.

so what shall I do now, screen is blank.
Is there some kind of fall back system, like 3 unsuccessful reboots -> revert back to other kernel or else?

lightdm faild to start after reboot, restart service start it, but every reboot failed

You may execute sudo mhwd -a pci nonfree 0300 to make sure all parts of Nvidia drivers got installed.

Update on three computers went fine:
1 * KDE and 2 * XFCE.
Kernel 5.4, 4.19, 4.14.


I use lightdm with XFCE 4.16 without any issues. Which UI do you use?
