安装NoMachine并解决无外接显示器桌面黑屏

NoMachine,是比较好的一款 remote-desktop软件，远程Ubuntu server安装后如果没有外接显示器如何使用？

利用自带显示服务，配置Xorg

如下：

1.下载安装 nomachine, 设置firewall配置

install nomachine_xx.deb

bash 复制代码

$ sudo dpkg -i nomachine_8.10.1_1_amd64.deb

allow firewall port

bash 复制代码

$ sudo ufw allow OpenSSh
...

Rule added (v6)
$ sudo ufw allow 4000
Rule added
Rule added (v6)
$ sudo ufw enable
Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
Firewall is active and enabled on system startup

reboot ubuntu machine

2. 无外接显示器？配置自带显示服务

headless mode：无外接显示器时，Linux不会启动桌面GUI，显卡就根本没有启动

solution : 停用X-Server，然后用nomachine自带的显示服务取而代之。

bash 复制代码

sudo systemctl stop gdm3 && sudo /etc/NX/nxserver --restart

fix white/back screen on ubnutu- force the login screen to use Xorg

bash 复制代码

vi /etc/gdm3/custom.conf

# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

# restart nomachine software 
sudo systemctl restart gdm
