Tested these versions:
v4.0-rc3
v4.0-rc2
v4.0-rc1
v3.19.1
All the v4 versions kept crashing (didn't boot into X) on "Floating
point exception" related (at least seeing "synaptics_drv" in the
backtrace) to the touchpad - see the uploaded Xorg.failsafe.log from
v4.0-rc1.
In v3.19.1:
- the touchpad works (gestures!)
- xinput says:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=11 [slave pointer (2)]
⎜ ↳ DualPoint Stick 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)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Integrated Camera id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]
- GPointing Device Settings shows both the stick and the touchpad
- Mouse and Touchpad also shows them both
- running `synclient` shows me config and not the error message
So far, from trying things out, it seems to work nice.
Will do the tagging you described.
Do you want me to upload some more logs, outputs etc?
