I found my mouse was too fast in linux mint. Found this and the settings were perfect. I was able to create the script "sudo chmod +x /etc/init.d/mousefix", but when I get to the last step in the following article (sudo chmod +x /etc/init.d/mousefix), the error I get is:
insserv: warning: script 'K01mousefix' missing LSB tags and overrides
insserv: warning: script 'mousefix' missing LSB tags and overrides
Here is the article: http://wiki.linuxquestions.org/wiki/Set_up_Gaming_Mouse
Any ideas? Running Mint 18 using a g502 mouse.
