Manjaro-kde-25.0.5-250713-linux612.iso?

Using our get-iso tool - you can get the latest unstable preview

get-iso plasma --full --preview

Tool available with manjaro-get-iso package.

For as long as you are using Nvidia GPU there is no guarantee.

When you have a working system - disable update-nagging - create a snapshot of the stable branch packages and use it to install extra packages - what ever - this way you don’t get continued updates.

From your topic history it seems that Manjaro is not the right operating system for your use.

Perhaps Linux Mint or Ubuntu is a better match.
