like hardware self-test do not show backWe need to change the resolution to add vga=791 to the kernel line.Note: The parameters of the VGA is not random input, can be modified as necessary, my computer above the highest only 16 bits, 24-bit parameters can not be effective, so select vga=791.RHGB quiet can be deleted also can be preserved, see oneself like. After the setup, you need to reboot the system, and then you can see the resolution is getting bigger and it looks much more comfortable ~ ~

Linux provides a daemon function that allows the process to run out of the console and achieve the effect of running in the background.
