PLEASE READ THIS FIRST:
This is not for beginners because you never want to take any chances of messing up your X display. Trust me, it's no fun when you try to boot only to be dropped down to a shell. So if you're not sure what you're doing and are not familiar with tweaking system critical configuration files please do not try this.
If you have a Nvidia Video Card and are using one of their proprietary drivers you don't have to look at the Nvidia logo every time you boot your computer. It's up to you if you want to see their branding every time you boot or not. If you are tired of looking at the Nvidia logo and think it only delays the boot process, time to get rid of it. In the xorg.conf file adding Option "No Logo" "true" in the Device Section will suppress the Nvidia logo from appearing as well as save a small chunk of boot time. It also makes the boot process more refined and without interruption.
Here's how to add it to your xorg.conf file without using the terminal console. Open Konqueror as root (or equivalent). One way to do that is to press Alt+F2 then type: kdesu konqueror
Then navigate to this directory: /etc/X11
Open xorg.conf with kwrite (or equivalent) and scroll down to Section "Device"
Then add this line:
Option "NoLogo" "true"
Now close out of Kwrite and save changes. The original file will be backed up automaticaly as xorg.config~ (save a copy of it).
That's it! Now when you boot no more Nvidia branding! No more staring at the Nvidia logo waiting to get to your desktop.
If you run into any problems to restore a standard xorg.conf file just type:
nvidia-xconfig as root in the console and a new xorg.conf file will be created with all the default values.
