Hide mouse pointer when running on a desktop

[stas.zy...@gmail.com]

Hi, I'm developing fullscreen kivy applications for a GNU/Linux based all-in-one desktop system with a touchscreen (MSI AE2051, AE201 etc)
The problem I have is that the mouse pointer is alway visible.
Is there a kivy way to hide it ? 
Or is it something that is handled at OS/desktop level ?

Thanks,
Stas

There is a kivy config option for this, you can see it in the settings panel if you press f1. I think it is the 'show_cursor' option in the [graphics] section, and you can use that information to set it manually.

I've read the Config API doc but somehow I've missed it :-(
Thank you.

It will hide the mouse cursor indeed, but there's a manor problem......
Then the touchscreen stopped working also ?!

Is there a way to alter the mouse cursor so that we can set it to one pixel or whatever ?
Kivy seems to draw it's own cursor because changes to the cursor made in the desktop don't have any effect when the cursor enters the Kivy window.

i met the same problem!

hide mouse via xlib not function in kivy env....

close "show_cursor" option in kivy config case touchscreen not work.....

Is there perhaps a way to replace the cursor for a all transparent image?
That way we keep touchscreen functionality but no visible cursor.

Can one of the kivy devs look into this issue,  or gives us some pointers to a possible solution, this issue keeps us from using kivy in our products :-(

ahaha!!

GOT IT!!!!!!!! 

cursor = pygame.cursors.load_xbm('cache/mouse1.xbm', 'cache/mouse2.xbm')

pygame.mouse.set_cursor(*cursor)

mouseXX.xbm is a 8x8 xbm file created by GIMP, with transparent backgroud!! it works!!!!!!!!!!!!!

Cool, marco, nice work :-)
I'm going to try it also.
This is why free-software is superior :-)

Yep, confirmed.
The solution Macro found will fix this issue on "PC touchscreens"
like the MSI AE* family.

True, my touchscreen is Acer (Advanced Silicon S.A. by lsusb)

It seems this solution stopped working with Kivy 1.9 ?!
The cursor is drawn regardless which image you load.
