What can I do to just keep my elementary OS Freya running smoothly and not freeze, not break (requiring new install and losing data and installed software)? It has been frustrating to say the least, several reinstalls. I want to know what might be a simple question: how to keep the install well oiled and not jamming (freezing) up, not breaking.
For example I mistakenly used synaptic to change display managers as I wanted to change the Greeter. I changed the video driver to binary Nvidia (proprietary) because Lightworks demanded that-- yup, my mouse moved at a crawl, had to reinstall. What I am saying is, should I just not change the graphics card driver, not change the Greeter, not change any wifi driver, not change the desktop manager (Pantheon)? Should I NOT install any updates once it is running, I mean I want to do whatever it takes to just have a working system for a few months, so frustrating doing reinstalls of the OS, then software, then data. All I need elementary OS to do is: Firefox, email, text editor, music player, MEGA cloud storage sync, LibreOffice, and Fade In Pro screen-writing software-- and I have all that working now. Plus I have the login Greeter wallpaper and desktop wallpaper I like. So what to do now so nothing breaks, Linux runs smooth and I can just be productive? At this point I am concerned about doing any software or even security updates, I don't want anything to disturb working installation. Thoughts, advice?
