Trackpad issues, but even weirder than usual

[Miguel7501]

Hello, I am fairly new to Linux and tried a few distros.
Kubuntu has been the best in terms of smoothness and battery life, so I would prefer to stick with it if possible.

Now for the issue:
Whenever I hibernate (and sometimes even after a reboot) my laptop, the trackpad stops working.
I have quadruple-checked every possible way of disabling it.
xinput shows it in the list of pointing devices and all the props make sense.
After hibernating, none of the values change and the settings look the exact same too.
I have not spotted any difference before/after except for the trackpad not doing anything. No mouse movements, no clicks, nothing.
Now for the weird part: The only temporary fix I have found yet is booting into windows and then back into Kubuntu.
A normal reboot changes nothing (except for the xinput ID sometimes), but windows somehow fixes it.
I have also tried updating everything. The issue has been present on all the distros I tried (Mint, Ubuntu with Gnome, Debian with XFCE)
but I have not really tried properly fixing it on those. My current workaround is to set the lid closing action to "Turn off screen" instead of Hibernate.
The Laptop is a Fujitsu T935, the Trackpad is a "SynPS/2 Synaptics TouchPad" according to xinput.
It also has a Wacom touchscreen and Pen digitizer, in case that helps anyone.

Thanks in advance for any help.

Not a solution but a question, rather than logging in and out of Windows, have you tried a hard re-boot as opposed to a soft re-boot?

[jglen490]

Just some observations. 8GB RAM, no SWAP partition. Do you have a swap file? If so, what size?

A dedicated SWAP partition is not a strict requirement, but having a swap file or a SWAP partition has benefits. 8GB RAM is not bad, and for a lot of uses is good enough. When I went from 8GB to 16GB, without any changes in my computer usage, the computer was just more responsive - and (if possible) "happier". But, that's a few bucks out of your pocket, not mine, so at least keep that in mind.

I have a 16gb swapfile, but with my light usage it hasn't been used yet. The system only needs 1200MB of RAM on its own, unlike windows, wich claims half of the ram in idle.
