How can I locate a file...or part of a file.
I have downloaded a software (Eaglesoft CAD) that has a known graphics problem.
This is what the FAQ say about how to fix it.
For solving these issues, please check the file xorg.conf. Usually it's located in /etc/xorg or /etc/X11. If it is the case that the composite extension is enabled or not explicitly disabled in the file, change the corresponding section or add the following lines:
Option "Composite" "Disable"
How do I locate xorg.conf? And once located, how would I change/add to the corresponding section?
