Hi gents, I've tried using gtf utility and copy the two lines to xorg.conf file and tried restart the machine, no changes happened. I've also tried to change the "_" with just a space and still not working. I did notice that for a blink when the fedora logo appears befor login window that the resolution was changed but then change back to lower resolution when it was on the login window. Please kindly advise what did I missed here?
