Bluetooth keyboard makes the cursor disappear

[Michael Hill]

Using Rawhide, with kernel
Version     : 4.17.0
Release     : 0.rc6.git3.1.fc29 (also 0.rc6.git2.1.fc29)
Architecture: x86_64

and libinput
Version     : 1.10.901
Release     : 1.fc29

my ThinkPad Bluetooth keyboard causes the cursor to disappear or become
unresponsive.

On Wayland, after activating the shell overview, the cursor vanishes. I can
get it back by disabling Bluetooth from the system menu and (seemingly)
switching to a console and back.

On X, the keyboard works until I touch the trackpoint. The cursor flies to
the shell hot corner, lights up Activities without opening the overview,
and stays. My laptop trackpoint or a USB mouse can then be used to move the
cursor.

Here's what dmesg says:
[91490.366114] usb 2-7: new full-speed USB device number 7 using xhci_hcd

Does this sound like a kernel bug?

Possibly. The best thing to do is file a bugzilla for tracking if you
haven't already.

I have this same problem, although with a USB keyboard rather than
bluetooth.

I think it's a regresion in the version of libinput in updates-testing.
Backing out to the older version solves it. See
https://bodhi.fedoraproject.org/updates/FEDORA-2018-899c7219fe

I intend to file a bug when I get a chance tonight, but if you beat me
to it please let me know the bug number.

Also, I should add: changing kernels does not :)

On GNOME IRC, a couple of people suggested libinput, and I found a bug from
last week that Peter Hutterer had reassigned to the kernel. I filed this
bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1583324

In case someone reads this before the bugzilla email :)

I really struggle to reproduce this here, the only potential culprit so far
is a NaN for the trackpoint range. This is trival to bisect on the affected
machines, so narrowing this down would really help. We're in rc2 territory,
I'd rather get this fixed before the 1.11 release. It would look bad ;)

Cheers,
   Peter

Peter, libinput-1.10.902-2.fc28 works for me.

Thanks,

rightyo, thanks for testing, much appreciated. I spent most of today looking
at trackpoint stuff (and, completely unrelated, a significant part of today
sighing, swearing and despairing) so while I'll just get libinput 1.11 out
with the revert as in 902-2, libinput 1.12 should hopefully possibly maybe
this time really fix trackpoint acceleration.

Cheers,
   Peter
