I visited the NVIDIA website downloaded the NVIDIA NVIDIA-Linux-x86_64-304.108.run drivers. I stopped my X server and terminated all OpenGL applications. I changed my run level to 3 so that it boot to VGA console and installed it. I successfully installed the driver, but after installing my resolution has changed to 640x480 and now I am stuck, and I can't access my sidebar.
I am a new user so I'll request a clear answer.
