When waking up from hibernation, the touchpad behaves different than before hibernation. It is usable, meaning I can move the cursor, use left and right click, scroll etc. but the behaviour changed. For example, the scrolling is inverted, no more three-finger middle click, touchpad stays active during typing (really annoying). But when I open the touchpad settings, they look unchanged. In addition, the touchpad is unresponsive to changes of the touchpad settings after hibernation. The behaviour returns to normal (like i set it) after reboot.
I tried the following which couldn't resolve the problem:
- deactivating and reactivating
SynPS/2 Synaptics TouchPad(like this) - Installing
Synapticsdrivers (to use instead of the defaultlibinputdrivers) withsudo apt install xserver-xorg-input-synapticsand subsequent reboot*
I wanted to try sudo rmmod i2c_hid + sudo modprobe i2c-hid (Source) but the first command returned rmmod: ERROR: Module i2c_hid is in use by: i2c_hid_acpi and I don't know how to proceed here.
*Although this was an upgrade in my view, as Synaptics offers richer configuration options.
Making Ubuntu recognize the touchpad as a mouse is not an option for me, as I would lose even more functionality that way.
I am using an HP ProBook 450 G6 with Kubuntu 22.04.
