    • 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
