+    ```shell
+    Using system config directory "/usr/local/share/X11/xorg.conf.d"
+    MESA-LOADER: failed to open vmwgfx (search paths /usr/lib/x86_64-linux-gnu/dri)
+    failed to load driver: vmwgfx
+    MESA-LOADER: failed to open kms_swrast (search paths /usr/lib/x86_64-linux-gnu/dri)
+    failed to load driver: kms_swrast
+    MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri)
+    failed to load swrast driver
+    couldn't get display device
+    ```
+    解决：缺失显卡驱动  
+    apt install libgl1-mesa-dri
