No touch input on Libra 2 #3

BHSPitMonkey · 2023-10-18T07:55:17Z

This project looks pretty cool! I just tried to run the latest Nickel release on my Kobo Libra 2, and though the main window appears and looks normal, the app doesn't respond to touch inputs. The clock still updates, so I don't think it's a crash/hang.

Weird, should be working

Hmm
Try running in a remote shell ( Koreader has a SSH server )

When launched that way, I get the following output:

The window appears on the device as expected, still not frozen (clock updates still happen), but this time if I touch the screen the window disappears and I'm back to seeing (and interacting with) Koreader instead. In this state, I'm still getting a partial update from Sanki near the top of the screen when the time changes:

but all touch events go to Koreader, and nothing new is output in the terminal where the command is running (except for a few more waveform_mode and Painted region updates).

Szybet · 2023-10-19T07:02:44Z

Turn off koreader, kill it from the terminal from htop, then launch sanki and touch the screen a few times for logs

Koreader is grabbing the input device for himself :-(

BHSPitMonkey · 2023-10-19T07:55:55Z

That seems to put me into a similar state as when I launch Sanki from NickelMenu (i.e. Sanki is visible, but touches anywhere on the screen do nothing)

Szybet · 2023-10-19T08:17:48Z

Well, any logs then?

Szybet · 2023-10-19T09:39:42Z

Try also with these arguments rnabled as true, should give some more logs

But still no further output when touching.

With the addition of QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event0:rotate=0 (instead of event1), I actually start getting output when touching the screen, and I'm even able to interact with the UI a bit -- but I can't reliably make the selections I'm trying to make.

Here's some samples:

Touching near the top-left:

Debug: "Contact state: Qt::TouchPointState(0)"

Interesting. Try some arguments with rotation and swapping the axes. As you can see they are unconfigured in some way resulting in some madness.

Im top right you should get max x and 0 y values in pixels ( it goes (x, y)). In bottom left (0, max y) and bottom right ( max x, max y)
