One command to disable Nvidia logo
The easiest way to do this is running below command in terminal (press Ctrl+Alt+T):
sudo nvidia-xconfig --no-logo
After that, you won’t see the logo in bootup any longer.
The other way is to manually edit the Nvidia config file. Edit the /etc/X11/xorg.conf by running below command:
sudo gedit /etc/X11/xorg.conf
add Option “NoLogo” to Section “Device”, make it look like this:
VendorName “NVIDIA Corporation”
BoardName “GeForce 9600 GT”
After that, save the file and reboot.
