fullscreen=false
fulldouble=false
fullresolution=original

to (as mine is 1366×768):

fullscreen=true
fulldouble=true
fullresolution=1366x768

How can I make it Fullscreen?? as it can be done on windows, with all fonts bigger and with larger working space

fullscreen=false 
fulldouble=true 
fullresolution=1366x768 
windowresolution=1366x768 
output=opengl

This config worked pretty well for me. It creates a window the size of your desktop display (which is almost fullscreen-it leaves just the top status bar) and you can always just enter fullscreen after that with alt + enter
