something from /etc/iniit.d/nvidia-glx

This is something of the file /etc/init.d/nvidia-glx
I find take serval seconds to run when boot, so I want to delete them from the file. Will it cause some problems?
What will the the following script do? Thank you!


setup_links () {
# check if all the symlinks are in place
