    注意：在xorg.conf中配置显卡总线地址BusID时，必须以十进制表示，比如lspci总线地址（以十六进制显示）为91:00.0，将其转换为十进制145:00:0（16x9+1）配置在xorg.conf中。

    • Driver的选择必须根据使用的显卡和系统的支持情况配置,在系统不支持的情况下可以使用modesetting代替测试，不一定配置成功

      • centos系统支持的驱动在/lib64/xorg/modules/drivers/

        # ls /lib64/xorg/modules/drivers/

      • ubuntu系统支持的驱动在/usr/lib/xorg/modules/drivers/

    startx -- -layout seat0 -seat seat0 -novtswitch -sharevts
     

    参数详解： man Xorg

    • -novtswitch: 如果操作系统支持，请禁用自动启动服务器时将X服务器重置和关机自动切换到激活的VT的功能
    • -sharevts: 如果操作系统支持，则与另一个X服务器共享虚拟终端。
