• Cause: The system lacks a driver for the discrete graphics card
• FIX: Modify the boot profile, set the standalone video card to boot does not load, the specific configuration is as follows:

sudo nano/etc/default/grub

will be inside the

grub_cmdline_linux=""

Switch

grub_cmdline_linux="radeon.modeset=0"

　然后保存文件并更新grub

sudo update-grub

　更新完成后重启
　如果上面的方式不能解决问题，可以尝试将

grub_cmdline_linux="radeon.modeset=0"

Change to

grub_cmdline_linux="nomodeset"

Note: Query error information via DMESG

DMESG | grep Radeon
