OK, Linux Ultimate seems to be based on Ubuntu. If it uses Ubuntu commands, I can give you some detailed help.
First, to compile a kernel driver, you need to install a few things.
linux-source (kernel source)
linux-headers (kernel headers)
build-essential (Ubuntu megapackage that will install many needed programs)
gcc (Linux C compiler)
I don't know exactly what LU uses to manage package installation, so you will need to figure out how to install the needed programs.
You then need to stop the xserver. It looks as if it is using the KDE desktop, so enter this command into a terminal window.
Code:
sudo /etc/init.d/kdm stop
You then need to go to a terminal, so use this key combination:
Ctrl+Alt+F1
Press these keys in that order, and hold them down until you have all three pressed. You should get a screen that is a blinking curser, asking for you to log in. Log in as your normal user, then you can go to the folder that has the nVidia diver file in it.
Code:
cd /home/<username>/file_location
Then, when you run the installation file, use the sudo prefix to give you root privileges.
Code:
sudo sh NVIDIA-Linux-x86-185.18.31.pkg1.run
Make sure you answer the questions (accept the legal BS), and allow it to look for a precompiled version. It will then compile the driver. Also let it configure the xorg.conf file.
Then reboot, and hope for the best!
