If you are currently using the free drivers (which is indicated by your screenshot) and you get errors from a program that tries to use your graphics card, wouldn't it be the logical conclusion at least to try the drivers from the manufacturer of the chip?

I would advice you to install the drivers from NVIDIA's official website.

Bad advice for someone who has to ask this question. This will work, but will leave the OP with a not working graphical system the next time the kernel/xorg get an update.
I strongly recommend to use the drivers from the repositories.

Because the installer from that site compiles a kernel module for your specific installed kernel. If you get a kernel update the compiled module will not work with the new kernel. That will cause X not to start. You first have to compile a module for the new kernel. Not very difficult for an experienced user, but for a newbie more or less unsolvable.
If you install the driver from the repositories the package manager (to be specific: the package manager invokes DKMS for this purpose) will take care of compiling a new module.
