Pygtk is compiled with --disable-numpy: https://garage.maemo.org/plugins/scm...mo&view=markup

And gnome-python in maemo is a very limited version.

so that's a no on GOGH...

Man, your "dead zone" is TINY compared to mine. This might actually explain a lot of the problems I've been having with my touch screen. Perhaps I shouldn't have let my 2 year old colour on the tablet with the stylus gripped in her fist like a digging tool.

Like you, I can use my finger in the "stylus dead zone", but I want to know how to calibrate my touchscreen to fix this stylus issue.

I agree that this looks like a hardware problem that MyPaint is uncovering.

Here is my ‘dead zone’, like other, left side. Note: this doesn't happen in mtpaint!
Note2: I am using an n800 and the latest mypaint.

Re: Hildonized Mypaint for 2008 OS
 

I checked out this thread, but their results didn't seem to be very conclusive, and I tried calibrating first with feather-light taps and then with hard presses and it doesn't seem to help either way. I tried using my finger on the calibration screen and that made it worse.

I wonder if there's some setting in "Configuration Editor" that might help this?

Again, your dead zone is tiny compared to mine. The red area on my screen is the GOOD zone, the rest is "dead".

Re: Hildonized Mypaint for 2008 OS
 

i really don't think this is a hardware problem....
if it was hardware, wouldn't it be just more than mypaint with deadzones..
I tried all the other draw/sketch/paint apps and all of them seem to work properly.
maybe its a problem with touch sensitivity.

All in all I'm happy its isolated to only mypaint...I would be very mad if it was an issue with my tablet.

qole, I feel for you...

Re: Hildonized Mypaint for 2008 OS
 

Interesting. Here's the problem in fullscreen. I scribbled systematically all over the screen, first one way diagonally, then the other way, then in circles. I wonder why the diagonals work in one direction in some areas, and in the other direction in some areas.

I really do believe it is a hardware and/or firmware problem being exposed by MyPaint, because I have had terrible problems with my touchscreen since I upgraded to OS2008. Drawing a solid line in Numpty Physics, for instance, is an exercise in frustration and futility... especially on the left side. MyPaint may just be more pressure sensitive than the other programs.

Are the touch screen grid sensors on the right-hand side, by any chance?

EDIT: According to this thread, Diablo will address a lot of the touchscreen issues. But there has to be some way to boost the pressure readings or something... The brush pressure settings (in opacity and radius) don't seem to make any difference.

Re: Hildonized Mypaint for 2008 OS
 

To clarify to onlookers of this thread that are making assumptions about the touch screen, this isn't happening to everyone.

Re: Hildonized Mypaint for 2008 OS
 

No, only to fathers of toddlers who keep dropping their devices. :rolleyes:

UPDATE: I logged some of the pressure values, and it looks like the dead areas of the screen are registering speed1, speed2, and stroke values, but they get press=0.000 in this area.

UPDATE2: The pressure values all seem really low, even in that "good" area in the top right corner.. The best I can get is 0.220, and that's dangerously hard. Most of the values (pressing hard) are falling around the 0.18 area.
