Fix Unresponsive Mouse & Keyboard in Ubuntu
If the mouse and keyboard are not responding in the Ubuntu system, it may be caused by the following reasons:
- Power issue: Make sure the mouse and keyboard are properly connected to the computer and ensure their power switches are turned on.
- USB接口问题：尝试将鼠标和键盘插入其他USB接口，或者尝试使用其他设备进行测试，以确定是USB接口故障还是设备故障。
- Driver issues: The problem with the device not functioning properly may be due to driver issues. Try updating or reinstalling the drivers for the mouse and keyboard.
- System settings issue: Check if the mouse and keyboard are disabled in the system settings, or try restarting the system to resolve the issue.
- Hardware failure: If the above methods do not resolve the issue, it could be due to a malfunction with the mouse or keyboard itself. Try connecting the device to another computer to test it, or replace it with a new one to fix the problem.
If none of the above methods work, it is recommended to seek assistance from a professional for inspection or repairs.
