Hi Lina,

As others have said - be really careful. 

Is it perhaps possible you may have a series of XY problems here? 

https://xyproblem.info/ - which also references Greg who is incredibly helpful
 on this list, especially with scripting problems.

Stating the all too-obvious here from the perspective of someone watching 
this from outside.

Write down for yourself what you actually want to achieve in the simplest
terms - not how you think it needs to be solved.

Break the problem down to it's simplest parts and steps. If you can't
break it down: ask here and someone will probably ask questions to help
break it down more fully.

Work out a starting point - that might be a simple reinstall of Debian
less graphics drivers and a windowing environment to start with.

The next step might be to build and install Nvidia drivers for your card

The next step might be to then add a windowing manager / desktop environment
(and so on).

Work up from there.

_Most_ problems can be solved this way, perhaps after a false start or two.
It may still be the case that you run into an impasse - in which case you
may have to start the process agin given the new constraints you now face.

With every good wish, as ever,

Andy Cater
