I'm experiencing a lot of trouble with Ubuntu (various flavours) and my laptop Razer Blade 15.

Occasionally the touchpad device stops working, except for accepting tap clicks, it does not scroll, nor moves the cursor or accept right clicks.

I've tried both xserver-xorg-input-synaptics and xserver-xorg-input-libinput but neither seem to solve the issue.

The only pointer I have is that when logging events for the touchapad, there is a stream of EV_MSC events being spit out when the device is not working correctly, along these lines:

Input driver version is 1.0.1
Input device ID: bus 0x18 vendor 0x4f3 product 0x30a6 version 0x100

I imagine more information might be needed but I am somewhat at a loss of what to do next. I've followed this to no avail. Would highly appreciate some advice.

I had a similar problem with my mouse not registering clicks randomly.

I did not get to the root cause of the issue. But I got around it by having a keybind to reload the mouse drivers.

#Disable driver modules
sudo modprobe -r psmouse
#Re-enable driver modules
sudo modprobe psmouse proto=imps
