How to enable the framebuffer on CentOS 7.

The Graphics::Framebuffer module requires the framebuffer to work. This is how I enabled the framebuffer inside a CentOS 7 virtual machine.

 Perform steps as root:

 1. systemctl set-default

 2. append vga=0x317 to GRUB_CMDLINE_LINUX line in /etc/default/grub.conf

 3. grub2-mkconfig -o /boot/grub2/grub.cfg

 4. add the user to the 'video' group in /etc/group


 5. reboot

 Perform as user:

 6. id

    uid=1000(mario) gid=1000(mario) groups=1000(mario),39(video)

    ensure in video group (if not yet rebooted, log out and back in)
