红帽全球峰会1.5. 更新和启用 xorg（Linux 虚拟机）
在在虚拟机上使用 GPU 之前，您需要在虚拟机上更新并启用 xorg。NVIDIA 驱动程序安装应该自动执行此操作。查看 /etc/X11/xorg.conf 来检查 xorg 是否已更新并启用：
# cat /etc/X11/xorg.conf前两行表示是否由 NVIDIA 生成。例如：
# cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 390.87 (buildmeister@swio-display-x64-rhel04-14) Tue Aug 21 17:33:38 PDT 2018流程
在虚拟机上，使用以下命令生成
xorg.conf文件：# X -configure使用以下命令，将
xorg.conf文件复制到/etc/X11/xorg.conf：# cp /root/xorg.conf.new /etc/X11/xorg.conf- 重启虚拟机。
通过查看
/etc/X11/xorg.conf来验证 xorg 是否已更新并启用：# cat /etc/X11/xorg.conf搜索
Device部分。您应该看到类似如下的条目：Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection
GPU 现在分配到虚拟机。
