How to adjust the screen resolution of Centos virtual machines in VMware after the Centos virtual machine is installed in VMware, the screen resolution is usually set to 800 × 600 by default. The screen resolution preferences window (system> preferences> screen resolution) cannot be used for setting. Generally, you can install VMware Tools to solve this problem, but this method is not the only one: 1) open the "Display Settings" window (system> Management> display), open the "hardware" tab, and click "Configure" in "display type". 2) select an appropriate Display model in the displayed "Display" window, for example, General LCD Display-> LCD Panel 1280 × 1024; 3) after clicking "OK", return to the "Display Settings" window, open the "Settings" tab, and select the appropriate resolution in the "resolution" tab; 4) Click "OK, the system will prompt you to restart the X server by running the command "running the command", and "running the command". After the server is restarted, you can adjust the screen resolution of a Linux virtual machine in the "Screen Resolution Preferences" window.
