Thank you kindly Andrew. How do I go about that?
what is the sequence of commands? I am not 100% familiar with working on files in linux yet.
Still need help......
Hmmm... well this is not the kind of change you want to do without some understanding of some Linux command line basics and then very importantly how to translate your screen setup requirements into lines in the Resolutions.conf
To get a console command line screen open do;
Ctrl+ALt+F2 (F3, F4.... etc etc are also ok)
Now type to open the resolutions.conf file in the nano text editor;
sudo nano /usr/pluto/share/Resolutions.conf
Now you need to add new configs to the Resolutions.conf to suit your screen
Hope this helps you
