Spy_Gentleman: Can anyone tell me what's the best drivers for NVIDIA GeForce GT240M? All this talk about the third party drivers and official ones makes me confused and, speaking of official drivers, is it better to install it from NVIDIA page or from the Additional Drivers menu in Linux Mint?
I'll try to explain as concisely as possible:
1a. nVidia's official drivers are the most advanced, but, because they're closed-source, you have to wait for nVidia to release updates in response to changes in Linux and nVidia's not going to continue to support old cards forever. In the short-term, they're the best solution.
1b. In order to ensure the best possible experience in the long run, people are working on reverse-engineering how nVidia cards work so they can release open-source drivers which can be updated at the same time as the Linux kernel and supported for as long as people are interested in doing so.
2. Always choose the Additional Drivers menu. The ones from nVidia's page don't know how to install themselves reliably because of how distros can vary and are more for people who are
building things like Mint.
