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
