Weird thing happened after my last update on my new laptop (Asus k401l), when it goes to sleep or when I close the lid, the touchpad is disabled and in system Settings > Input Devices > Touchpad it says "touchpad not found" in red. Worked fine before the sleep mode came on.
I have tried with no solution:
- using hot keys Alt+F9 (was working before sleep mode);
- reinstalling Kubuntu.
What should I do?
