Does nouveau support RTX?

I often hear how prprietary drivers breaks and have a lot of issues. But AMD card usally work very stable

You should try OnlyOffice. It is very similar to MS Office and fully compatible with Microsoft formats. It has fully replaced MS Office for me for all office work. Also it can be easely integrated with your private NextCloud. You can install it from Flathub.

Edit: it also lets you edit and convert pdfs like Adobe Acrobat Pro
