I checked whether nvidia-glx is installed or not using
sudo apt-get install nvidia-glx
and found "package nvidia-glx is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only availabe from another source.....Package nvidia has no installation candidate"
It tried to download nvidia-glx-1.0.9639+126.96.36.199-14.9_i386.deb
I have found nvidia-glx
Somebody pls suggest me which should I download and how I can use/install.
