Hi Kevin,

The Bluetooth and tablet issues are likely to be unrelated. The
Bluetooth button is completely independent from the rest of the
tablet, with neither the tablet sensor nor the Wacom driver being
aware of it.

From what I understand, in normal operation the Bluetooth button is

disconnected most of the time. When you press it, it briefly wakes up,
connects to the paired PC, appears as a keyboard, sends a key combo,
and then disconnects until you press it again. If you run something
like `sudo libinput-debug-events` and then press the button, you
should be able to see the key combo being sent (as well as the
connect/disconnect). I'm not sure what's up with the deadlock warning
that appears in dmesg, however...

Ah, quite right. Sorry about that, this is my first device with a pen. I
expected it to just connect and stay there, but I suppose doing things
this way saves a ton of power since it's likely not writing most of the
time.

As for the tablet, the "last error = -121" indicates that we got an
EREMOTEIO error. I've not come across that particular error in this
function before. I'll need some time to track down why we might be
getting this from the lower layers.

ok, thanks! If you need any more info from me just ask. Happy to test
patches or gather more info.

Greetings.

I'm running into some problems with Lenovo active pen 2 and wacom tablet
on a new yoga 920.

Filed:
https://bugzilla.redhat.com/show_bug.cgi?id=1514837

but I thought I would ask here if anyone had any ideas...

Basically when pairing the pen it shows for a second, then drops:

The wacom tablet is never connecting:
