Than you all.

i remover the /etc/X11/xorg.conf and am using the nvidia-settings only now ,
i just did xrandr --dpi 118x118 and the graphics are awesome now , however i ahve to do this command each time i boot the os ,how can i make it permanent ?

If on KDE, use Systemsettings - Fonts - DPI.

to make the nvidia-settings permanent you’d have to export them to the xorg file you removed
just run nvidia-settings as root set all your preferences and hit export to xorg file you’d have to manually set the path to that file as it’s blank in the settings tool

/etc/X11/xorg.conf
