Comment 50 for bug 1366421

Glad it works for you, thanks for testing, Ritesh.

> I'm just curious how you came up with the number 70/71 for my setup ?
Honestly, I don't know anymore. What I think I did was to remap two keys on my USB keyboard with setkeycodes, in order to emulate TouchPadOn/Off manually. Then 'xinput test-xi2 3' and Onboard's GlobalKeyListener both gave me 70/71. Those values seemed odd, but hey they worked.

However, now I'm apparently unable to reproduce this. setkeycodes from my notes does nothing, and when I remap keys with UDev hwdb (instructions in /lib/udev/hwdb.d/60-keyboard.hwdb) 'xinput test-xi2 3' gives me 200/201. Ahd frankly, that makes more sense, as those are the keycodes from your output in comment #39.

So, I don't really know why it works with 70/71. If it ever happens not to anymore, try 200/201. Meanwhile, I'm wondering if Onboard uses hotkeys at all for tablet-mode switching, or if any of the two other approaches have started working. 'onboard -ddebug', while going tablet and back, would clear that up, mainly the HardwareSensorTracker entries. You could attach the output here, or just look at mainly the HardwareSensorTracker entries yourself.

Yes, possibly. If it turns out that Touchpad status is the only way the firmware allows to detect tablet-mode, then they might as well bake that into the ideapad-laptop driver and send SW_TABLET_MODE.
