PS: Possible problems:

a, black screen Install and configure the VNC server in Linux, and find that there are black screens when multiple users log in. The specific phenomenon is: The client can pass IP and The session number logged into the system, but the landing was dark, except for a fork-shaped mouse. Cause: The user's VNC startup file permissions are not set correctly. Solution: Change the attribute of the xstartup (usually: /home/username/.vnc/xstartup) file of the black screen user to 755 (rwxr-xr-x). b, vnc can input numbers, but can not input letters. Reason: vnc server will require the input method of the OS of the vnc viewer to be the same as the language of the OS of the vnc server. Solution: Generally, the Linux OS we installed is E-text, so when using vnc viewer, please close the Chinese input method of the local OS and switch to English.
