Do you see a little circle red thing in the middle of keyboard? This is called "Trackpoint mouse". It is super helpful most of the time but as the computer gets old, it starts to annoy very much. Your mouse will move on its own and you have no control on it.
If you had the same problem then you can follow these steps to permanently the function of the Trackpoint mouse:
Linux:
Open terminal and write the following codes
1. Write the following code:
xinput
[Note: Xinput will list the devices that are currently connected in your laptop/computer. Find the name of your device. For me it was "AlpsPS\2 ALPS DualPoint Stick". Your might be of similar one. ]
2. Take the note of the id that is with your device.
Example: AlpsPS\2 ALPS DualPoint Stick id 15
3. write the following code:
xinput -list-props "your id number"
example: xinput -list-props 15
4. Take the note of the id that corresponds to "Device Enable".
Example: Device Enabled (141): 1
So here "Device Enabled" has an id of 141
5. Write the following code:
xinput "device id" "device enabled id" "1 for enable/0 for disable"
Example: xinput 15 141 0
