Comment 224 for bug 1791427

I can confirm this bug is present for me too:

MSI GS 65 Stealth Thin
Ubuntu 23.04
SynPS/2 Synaptics TouchPad

Am happy to provide any detail. I've tried a bunch of things over the
years.

I have noticed that if, after opening the suspended laptop, I wait about
10-15 seconds before touching the touchpad, it is more likely to wake up.
Also, when I do touch it, I just barely touch it without moving my finger.
I find that if I can get the pointer to move just one pixel at first, then
touch it again, it is more likely to wake up.
