Hi Folks

I am just a beginner in Linux. I ma trying to install Graphic Card Drivers but I get below Error.

Can you provide me step by step how to fix it ?

This system has a graphics card which is no longer handled by the
│ NVIDIA driver (package nvidia-driver). You may wish to keep the
│ package installed - for instance to drive some other card - but the
│ card with the following chipset won't be usable:

│ 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF116M
│ [GeForce GT 555M/635M] [10de:124d] (rev a1)

│ The above card requires either the non-free legacy NVIDIA driver
│ (package nvidia-legacy-390xx-driver) or the free Nouveau driver
│ (package xserver-xorg-video-nouveau).

│ Use the update-glx command to switch between different installed
│ drivers.

│ Before the Nouveau driver can be used you must remove NVIDIA
