Public bug reported:
Binary package hint: xinput
Hello,
I got an HP 6910p with a Synaptics combo trackpoint and trackpad.
Thanks to the XInput2 we can split the trackpad and the trackpoint to
get two cursors. But there is a problem (exact location in the code to
be clarified: xinput or synaptics), the event sent at xinput level for
the mouse keys are send thru the same master pointer (either if it is on
the pad or on the trackpoint area).
Here is the sequence :
xinput create-master Test
xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ "SynPS/2 Synaptics TouchPad" id=10 [slave pointer (2)]
⎜ ↳ "PS/2 Generic Mouse" id=11 [slave pointer (2)]
⎜ ↳ "Macintosh mouse button emulation" id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ "Power Button" id=6 [slave keyboard (3)]
↳ "Video Bus" id=7 [slave keyboard (3)]
↳ "Sleep Button" id=8 [slave keyboard (3)]
↳ "AT Translated Set 2 keyboard" id=9 [slave keyboard (3)]
⎡ Test pointer id=13 [master pointer (14)]
⎜ ↳ Test XTEST pointer id=15 [slave pointer (13)]
⎣ Test keyboard id=14 [master keyboard (13)]
↳ Test XTEST keyboard id=16 [slave keyboard (14)]
xinput reattach 11 13
At this point you have two pointer :)
But buttons are not matching :
xinput test-xi2
when clicking on left button of the trackpoint :
EVENT type 15
device: 2
detail: 1
valuators:
when clicking on left button of the trackpad :
EVENT type 15
device: 2
detail: 1
valuators:
As a result the trackpoint cursor is unsable as you never get buttons
"click" event ;-)
Here is the grep on dmesg for Synaptics :
