How to use mouse in Black screen

A programme called GPM (General Purpose Mouse) enables the use of a mouse in the text console of operating systems that resemble Unix, including Linux. By recording mouse events and converting them into corresponding console actions, it offers mouse support.

The mouse input is typically lost when using chvt (change virtual terminal) to switch between various virtual terminals in the console. However, even after switching virtual terminals, you can still use the mouse by running the gpm daemon.

On many Linux distributions, you can use the package manager to install gpm.

yum install gpm

Start the service gpm

Use The TIME before any cmd to see the time how much taken
