- 原因：系统缺少独立显卡的驱动
- 解决：修改启动配置文件，将独立显卡的设置为开机不加载，具体配置如下：
sudo nano /etc/default/grub
将里面的
GRUB_CMDLINE_LINUX=""
改为
GRUB_CMDLINE_LINUX="radeon.modeset=0"
然后保存文件并更新grubsudo 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"
更改为
GRUB_CMDLINE_LINUX="nomodeset"
注：通过dmesg查询错误信息
dmesg | grep radeon
