how to set display resolution permanently even after reboot

Use System -> Preferences -> Display menu option or gnome-display-properties tool to configure desired display resolution for user.

This tool will create '~/.config/monitors.xml' file which will be referred each time upon user login.

The same file can be copied to /var/lib/gdm/.config/ directory for gdm to have that display resolution upon reboot.
