So I changed the firmware to report 64k*64k, and then started to move the cursor with the touchpad functions towards the bottom right corner. Lo and behold, it reached the corner at 1980x1080, which happens to be the resolution of my screen. So it appears that no scaling is done, even though <a href="https://cgit.freedesktop.org/xorg/driver/xf86-input-libinput/tree/src/xf86libinput.c#n68">https://cgit.freedesktop.org/xorg/driver/xf86-input-libinput/tree/src/xf86libinput.c#n68</a> suggests there should be. IIRC, I had to remove line 1344 (<a href="https://cgit.freedesktop.org/xorg/driver/xf86-input-libinput/tree/src/xf86libinput.c#n1344">https://cgit.freedesktop.org/xorg/driver/xf86-input-libinput/tree/src/xf86libinput.c#n1344</a>) for absolute events to get handled... so perhaps the problem is being on the same node and/or not having the BTN_TOUCH_* flags? (For the record, all we want from this touchpad emulation is absolute positioning, no clicking, palm detection, or anything like that - there is no real touchpad in play, just regular keyboard keys sending touchpad events)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
