I have a wireless mouse, but Ubuntu shows, that it has 5% battery, and as a result is dimming after 30 sec of inactive. How can I turn it off?
SOLUTION:
Download some software to control behaviour of your device (in my case it was SetPoint) and then change the right things in settings there(in my case I had to disable notifications). If you cannot run the software on your OS as it was in my case. You can use Virtual Machine.
Thanks to @PRATAP for help.

Go to system Settings, Power, in the Power Saving area you will find "Dim Screen When Inactive" Turn it off.![enter image description here](https://i.stack.imgur.com/GoV9g.png)
