When a software conflict results in a device not being recognized, it usually stays unrecognized. When a hardware problem (like mouse or keyboard) is intermittent, coming and going, it usually is due to the connection of the hardware since software conflicts do not arbitrarily "go." They arrive and they stay.

Could you please try changing the port you are plugging your keyboard and mouse into? If using a USB hub, switch to plugging directly into the computer. If you are using the ports on the back of a tower, try switching to the ports on the front.

Some notebooks (laptop) have a single cable for mouse and touchpad and keyboard.

still sometime have lag keyboard and mouse is there is log i can find ?

You can check /var/log/syslog. I am not aware of a log specific to the Mouse and Keyboard.
Other things you can try aside from changing to a USB 2.0 port instead of USB 3.0 port:
Check your display Refresh rate- Commonly it is around 59 hertz.

Some say evdev for xorg performs better in this regard:

sudo apt remove xserver-xorg-input-libinput

sudo apt install xserver-xorg-input-evdev

Still not have solution for this problem its driver ? i am using dual monitor

How is your mouse/keyboard connected to the system?
Cable? USB? Bluetooth?

If it were wireless connection, it might helps to move a receiver to the front of the tower (if that is what you are using).

i am using logitech MK275 wireless mouse keyboard , can this happen because update zorin ?

Does configuring with

sudo dpkg-reconfigure keyboard-configuration


If you scroll through the list, do you see anything for Logitech?
