Double tap in kde plasma mobile

I am shocked, played a little with a Pinephone and Manjaro KDE Plasma mobile (what a name) and it supports double tap to wake which used to be sailfishOS’s signature feature. Well, one of them.

The times when double tap to wake was one of the characteristic function of sailfishOS are probably over.
And it seems that with the Xperia 10 II it is also low-power mode.

true, but sometimes I still miss it on my XA2. On the other hand, PinePhone does not even have Fingerprint recogition. So it wakes on double tap and you must enter a PIN, very uncomfortable by today’s standards, so to say. Ore you make it PIN-less which is not safe.

When I first read this, I thought you must be joking. But with the GT917S panel,

wake-up can be achieved by swipe, double-tap, or writing specified letters on the touch panel.

Last quote is from manufacturer’s data sheet. So you’ll never stop learning, and I’m still very impressed by this odd beast in my drawer (which has been my main phone for a whole month in early 2021).

does that mean the Pinephone would support even more screen actions which are not (yet) implemented? I am very interested in sxmo PistmarketOS which shows a good deal of alternative screen actions (but no double tap, so far)

Well, the hardware surely does. The operating system has to make use of it using the panel’s Linux driver, which itself has to support the gesture mode (which it does, using its gtp_enter_doze() interface). So I’d guess SXMO does not enable gesture mode while KDE Plasma obviously does.

Can you confirm that on KDE Plasma, the device wakes up on swipe events, too?

no, it doesn’t. I think not even double tap works. The screen dims, then shuts off, but a touch will still wake it. After a while, touch shuts off too, and whether aou double tap or single tap does not matter. So my double tap discovery was just a matter of sweet Jolla 1 memories ;( (I belive). Funny thing is: Double tap even after 2 Minutes works, but after 30 minutes: No double tap on screen. Double click on power button is necessary ;(

Fortunately i may correct myself in my above posting.
With mcetool --set-ps-on-demand=disabled
and mcetool --set-low-power-mode=enabled low-power-mode is working well and it causes no problems with proximity sensor on my Xperia 10II with SFOS 4.2.0.19 EA so far.

with XA2 I use fingerprint so double tap is obsolete (but I liked it). With Pinephone there is no fingerprint, so doubletap is welcome. But in KDE plasma mobile, the feature is not very consistent. Seems to get stuck in deep sleep, or something.
