OpenSUSE Xfce. That's when I took to creating a new xorg.conf file with necessary parameters!

Create a file by name xorg.conf with the following contents:
The xorg.conf must now be copied to /etc/X11. Use the below command to do that:
Now restart the machine to see the changes persist.
Note: I did try to directly create the file in /etc/X11 folder but the text editor failed to come up when invoked as 'root' through terminal. As I mentioned above, it was a custom Linux with lot of features absent!
