I am running Manjaro in Lenovo g50-45 since past 3-4 years without any major issue . Since couple of days i am facing touchpad not working. When i check in settings in input device - touchpad it says device not found but after i close the lid and again open it the touchpad starts to work after few seconds and for very brief period there come touchpad off written on screen. my f6 key has toggle function to onn/off touchpad , even that button is not working.Even When booting in windows touchpad doesnt work . Please Help , i have tried the solutions provided in forum on touchpad freezing after suspended/sleep but is not working.

Tried
`-sudo modprobe -r psmouse && sudo modprobe -a psmouse
but the problem remains

Kindly help :slight_smile:

Does an external USB mouse work? If it does then try some other distro and if the touchpad doesnt work with other OS, the there is something wrong with touchpad hardware. Also try switching kernels.

External USB mouse does work . I tried Live usb of manjaro as well as endevour Os the problem remains same. The touchpad does not work . After closing the lid and the bringing it back from suspend once , the touchpad starts working. in libinput events elantech rouchpad is added last as you can see in my output
