HP EliteBook touchpad works different after it comes back from sleep

Support & Help Requests Hardware

Hi, I’ve been trying to setup the touchpad on my HP EliteBook but it has not been an easy task.
If I open the Mouse settings, there is no Touchpad tab there.
Trying to set it from the terminal is like I’d do nothing.
I am on Ubuntu Mate 16.10.

For example I hate tap-to-click. Especially that feature that, if you double-tap fast, it emulates a “keep it clicked” state and I just start selecting stuff or just can’t control it very well. I also would like to disable the touchpad while I’m writing, and I’d like to reverse the scroll direction with the two-fingers touch.

Thing is… I have noticed that all these behaviours disappear after a sleep -> wake up transition.

It’s like if it loads some different drivers or settings.

How can I debug this problem and find a way to make the laptop boot up with the “after woken up” settings? :stuck_out_tongue:

Thank you for your time

Do you have synaptics touchpad drivers installed ? Becouse Mate doesn’t have libinput support in 1.16 release and previous , and that may be the reason for odd behaviour and missing touchpad configuration options .

I have both synaptics and libinput installed.
Just to be sure we are talking about the same packages, could you please
write their names?

The synaptics touchpad driver :
xserver-xorg-input-synaptics
And there is no way you wouldn’t have libinput since it will break the xserver .

I can confirm I got that package and xserver-xorg-input-libinput both installed.

When the laptop comes back from sleep, I notice that the touchpad device gets mapped to a different point.

I'm going to show the results of two dmesg outputs, each after a resume:

➜ ~ diff dmesg1.txt dmesg2.txt | grep input
[ 458.142294] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio3/input/input27
➜ ~ diff dmesg2.txt dmesg3.txt | grep input
[ 961.342385] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio3/input/input35

Can this help solving this problem? Is there a way to force that remapping? Maybe that would save me from doing a forced sleep-resume.

I have upgraded the system to version 17.04 and now I don’t have the possibility to get my “favourite” behaviours after a sleep/wakeup session. It stays the same as before the sleep, so I can hate it 24/7 :stuck_out_tongue:
