Did you try the easy install method and it also does not work out? And what you mean by does not work? Is your Graphics Card not recognized by the system? Does your system still use the default graphics driver?

Therefore the pascal graphics card behavior still will be somewhat fluffy. Nevertheless, you will be able to work with the expected and accurate screen resolution and with adequate video acceleration.
We have to make it run also on your system! Let's do it step by step... What did you do so far?
