I have KDE installed with debian, and every time the PC is put to sleep mode, the touchpad (USB mouse works fine though) becomes non-responsive. I tried most of the solutions online which mostly suggest trying:

sudo modprobe -r psmouse
sudo modprobe psmouse

But this doesn't work at all for me. Where is this problem coming from?

So, this issue is resolved. I noticed this doesn't happen because PC is suspended but only when I close the laptop lid. Apparently it's a KDE-specific issue. when I toggle the touchpad on after PC resumes, the touchpad works fine.
