Installing Nvidia driver with '.run' extension in Ubuntu
I am trying to install Nvidia card driver. The driver has got a .run extension and i don't know how to handle that, I've tried to extract like i did with .tar files but didn't work. I clicked the file while in X window and it opens a terminal and runs for a sec and said i have to exit X window and run as root. so i exit X window and login form CUI, navigate to the folder and type "NVIDIA-Linux-x86-185.18.08-pkg1.run" but nothing happens, so i add sudo and tried but All i get is "NVIDIA command not found". I guess this is not a problem but i just don't know how to handle the .run file. please help. I am using Ubuntu Lucid Lynx LTS. I' ve checked other threads and found some issues regarding Nvidia drivers but i wanna know how to handle the .run files.
If you guys are not so busy I would like to ask one more thing. I've windows xp, 7, Puppy Linux and Lucid Lynx on my desktop and whenever i repair windows the GRUB got damaged. Is there a way to recover the loader without reinstalling the whole linux OS like getting into recovery console and fixboot,, fixmbr for restoring windows? I am sure there must be a way but i don't know. to be honest i did check out some of the threads but couldn't find it yet.
