根据Ubuntu MATE官方网站的说明
Enable and Disable X11
You can disable/enable the desktop environment using raspi-config.
If you only intended to run as a headless server then the official Ubuntu Server 18.04.2 images mightt be of interest:
•https://wiki.ubuntu.com/ARM/RaspberryPi
官方Wiki摘录以下内容
Accelerated X driver
An accelerated x.org video driver is available (fbturbo), though this is limited to hardware accelerated window moving/scrolling on the Raspberry Pi. Install the optional PPA above, then:
$ sudo apt-get install xserver-xorg-video-fbturbo
Then add this to /etc/X11/xorg.conf (create if it doesn't already exist):
Section "Device"
Identifier "Raspberry Pi FBDEV"
Driver "fbturbo"
Option "fbdev" "/dev/fb0"
Option "SwapbuffersWait" "true"
EndSection
根据官方说明创建/etc/X11/xorg.conf，V11VNC进行连接时的Xorg.0.log文件内容：
