Question

As a programmer I found it very hard to use my laptop and workstation with two different input devices, Can anyone suggest a good solution to use single mouse and keyboard to control my two machines

I am not looking for a Virtual Machine or RDP solution to see my machines in a single monitor,

Answer 1

Synergy.

Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s). Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Furthermore, it synchronizes screen savers so they all start and stop together and, if screen locking is enabled, only one screen requires a password to unlock them all.

P. S.
