KDE plasma freezes all the time

I’m not sure then why it fails, I’m no expert so I can’t help more to install this specific package. However, there is an alternative, it is to install the same kind of package manually, following this guide here

[HowTo] get legacy 340xx NVIDIA drivers back

Prepare your system for building drivers you may want to install development tools:sudo pacman -S git base-devel then you may want to install your proper kernel headers:sudo pacman -S $(mhwd-kernel -li | grep '*' | cut -d ' ' -f5 | awk '{print $0,"-headers"}' | sed s'/ //'g) 340xx (dkms for kernel 5.4 or 5.10 only) You need to get the sources first: git clone https://gitlab.manjaro.org/packages/extra/nvidia-340xx-utils.git git clone https://gitlab.manjaro.org/packages/multilib/lib32-nvi…

But you will also need to manually add a configuration file to bypass incompatibility with the current xorg in Manjaro, following these instruction, before rebooting:

Create the file /etc/X11/xorg.conf.d/30-nvidia-ignoreabi.conf from terminal

sudo nano /etc/X11/xorg.conf.d/30-nvidia-ignoreabi.conf

Copy and paste the following to this file

Section "Files"
  ModulePath   "/usr/lib64/nvidia/xorg"
  ModulePath   "/usr/lib64/xorg/modules"
EndSection

Section "Device"
  Identifier "Nvidia Card"
  Driver "nvidia"
  VendorName "NVIDIA Corporation"
EndSection

Section "ServerFlags"
  Option "IgnoreABI" "1"
EndSection

Save the file and exit nano text editor by pressing CTRL+X then Y (you can follow at the bottom what it does). It should bring you back to the terminal.

Reboot and see if it works. it may not work in which case we could revert changes from terminal, but I’ll add info if needed in that case (tell us if you can access the forum in case your computer can not properly boot then, or make sure you can access forum from another device before trying these instructions).

//EDIT: It may also be required to make sure the Nouveau driver is blacklisted so it doesn’t load, to do that first create a config file for modprobe:

sudo nano /usr/lib/modprobe.d/blacklist-nouveau.conf

then copy and paste the following in it

blacklist nouveau

then save and exit nano editor with CTRL+X then Y

But first try without blacklisting Nouveau, if it all works verify in inxi that the Nvidia driver is properly loaded and working for your video card, and then you could blacklist it to make sure it never loads.

//EDIT: also another needed step is to add the Nvidia packages to the ignore list to avoid the similar AUR packages to try to install/update and replace these ones just installed manually (which they can’t install install/update/replace because of the difference in kernel between Arch and Manjaro, example above for failure), easy to do directly from Pamac preferences → Advanced → Ignore List (searching for Nvidia and selecting the packages)
