在Mac虚拟机里的终端执行下面的命令，执行完之后重启即可 1920*1080分辨率：  
sudo nvram AC20C489-DD86-4E99-992C-B7C742C1DDA9:width=%80%07 
sudo nvram AC20C489-DD86-4E99-992C-B7C742C1DDA9:height=%38%04  

3840*2160分辨率：  
sudo nvram AC20C489-DD86-4E99-992C-B7C742C1DDA9:width=%0F 
sudo nvram AC20C489-DD86-4E99-992C-B7C742C1DDA9:height=%70%08 

解释：  
width=%0F 是宽度的16进制表示，将四个数字倒过来写就是 00 00 0f 00, 相当于十进制的3840 height=%70%08 是高度的16进制表示，将四个数字倒过来写就是 00 00 08 70, 相当于十进制的2160 所以，上面的两条命令执行完之后，分辨率将被设置为 3840*2160， 其他的分辨率依此类推 注意：1.vmware虚拟机对应的vmx文件里面的这部分内容要修改一下，设置一下最大分辨率svga.autodetect = "FALSE"svga.maxWidth = "3840"svga.maxHeight = "2160" 再然后下载VMware15对应的vmtools安装，重启机器然后在看是否生效。

noip for ubuntu

note for myself

Install noip2 from source

• cd /usr/local/src/
• wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
• tar xf noip-duc-linux.tar.gz
• cd noip-2.1.9-1/
• make install

If you get make not found or missing gcc then you do not have the gcc compiler tools on your machine. At https://help.ubuntu.com/community/InstallingCompilers you can find install instructions if you need help.

Configure the Client

As root (or with sudo) issue the below command:

/usr/local/bin/noip2 -C (dash capital C, this will create the default config file)

Create a Systemd service

Create the file /etc/systemd/system/noip2.service and paste the following:

[Unit]
Description=No-IP Dynamic DNS Update Client
Wants=network-online.target
After=network-online.target

[Install]
WantedBy=multi-user.target
Alias=noip.service

[Service]
Type=forking
ExecStart=/usr/local/bin/noip2
Restart=always

Activating

 $ systemctl daemon-reload

$ systemctl status noip2.service

$ systemctl start noip2.service (start immediately)

$ systemctl enable noip2.service (start on boot)

noip2.service

# Simple No-ip.com Dynamic DNS Updater

#

# By Nathan Giesbrecht (http://nathangiesbrecht.com)

#

# 1) Install binary as described in no-ip.com's source file (assuming results in /usr/local/bin)

# 2) Run sudo /usr/local/bin/noip2 -C to generate configuration file

# 3) Copy this file noip2.service to /etc/systemd/system/

# 4) Execute `sudo systemctl daemon-reload`

# 5) Execute `sudo systemctl enable noip2`

# 6) Execute `sudo systemctl start noip2`

#

# systemd supports lots of fancy features, look here (and linked docs) for a full list:
