nvidia-settings, can't change my screen resolution. [Solved]

That one ( "MX Live Usb Maker" ) is just to write an iso to a usb (to prepare a bootable usb stick).

So, you can use either an official iso,
or first create a snapshot of your current system ("your own iso" with "MX Snapshot" ) and choose "Resetting Accounts" at second step:

Well, I used a downloaded and proved iso without the snapshot of my own system so that others can install the clean version of MX on their machines doesn't matter what hardware is installed on their Machines.

As I created a snapshot of my system I can create with that tool a live stick, especially for me and my machine. Will do that in the next few days.

So for that moment this thread can really be marked as solved and can maybe be helpful for others with similar problems.
