I'm using TrueOS (FreeBSD12 current) in my hard disk. when it start after installed it. it suggest VESA to install but when i choise the vesa drive the screen changed to white , i rebooted and changed the driver to intel and it done but the backlight dosn't well i think the driver not well. How I can download the suggested driver vesa and use it. I'm using grub2 and dual-booting TrueOS with a arch and fedora.
