lcd monitor
 

i heard that lcd monitors are supposed to be utilized with a 60hz refresh rate nad when i checked my pc and laptop they both were set to 60 but my ubuntu is set to 75 and cant be changed, resulting in a flicker on the screen quite frequently. anyone know how to change the rate

sudo dpkg-reconfigure xserver-xorg when it asks you for the resolution and frequency, just select the 60Hz ones and deselect the other ones...

alright thanx. i wish i would have done that before i messed up the xorg.conf file

I had the same problem. I'll try your solution pljvaldez
