goodix panel - stylus hovering
Good news, I've written a patch to properly report the stylus/pen events as stylus events and submitted this upstream, see: https://lore.kernel.org/linux-input/20211207100754.31155-1-hdegoede@redhat.com/T/#t |
Created attachment 284207 [details] goodix panel - finger touch HELLO Let's straight to the point ;-) Problem : The the stylus for the touch screen ( Goodix-TS i2c-GDIX1002:00: ID 9111, version: 2020 ) under ANDROID and LINUX. The stylus works .. but : - hoovering over the screen triggering BTN_TOUCH ( but shouldn't ! ) so trigger buttons , sliders , etc. As you know should do it ( BTN_TOUCH ) after touch the screen ... not earlier... Like you see on the pictures ( longer selection is for the stylus hoover and shorter one for the finger ) system is not able to recognize if we're using the finger or the stylus . I'm getting exactly the same data ... I checked the goodix.c parameters but is not returning anything about the hovering or the stylus ... The only difference I noticed is during hoovering the stylus returning parameter ABS_MT_WIDTH_MAJOR = 0 but touching by the finger to touching by the stylus return = ! 0. If you need any mode data please ask. Thanks for help .
