So, I've been trying to run Steam on my computer (hp Pavilion dv7, Ubuntu 12.04), but I end up with the following error :
Xlib: extension "GLX" missing on display ":0".
After some research, I understood it has something to do with Nvidia drivers I should install.
I ended up on this page : https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia , saying I should use this command line :
jockey-text -e xorg:nvidia_current
Here is my question : What do I replace "nvidia_current" with? Or how do I find it out?
I tried going in "System settings" -> "Additional drivers", but all it shows is that I have a "Broadcom STA wireless driver" installed, it says nothing about GPU drivers.
Excuse my noobness, I'm a complete beginner and new to Ubuntu.
Oh, and my GPU is an Nvidia Geforce GT630M - 2GB
Any help will be greatly appreciated!
