[Qemu-devel] [Bug 1718719] Re: qemu can't capture keys properly under wayland

[ChristianEhrhardt]

Hi Mathieu,
thanks for the report but since we are up-to-date with qemu and I can't find an obvious breakage we might have introduced for this, this should go to qmeu-upstream in this case.

Furthermore are these actually two issues?:
#1 - wayland crashes under spice
     more of a wayland bug then I'd expect, but upstream qemu
     might have heard of it and have good pointers
#2 - new qemu does not recognize keys correctly with the default (SDL I'd think) frontend?
     That is worth to report upstream qemu for sure.

I added an upstream qemu (and a wayland) task and you can help them to
recreate in case they have questions on how exactly to do so.

[ChristianEhrhardt]

I wanted to write steps to reproduce, which should be as simple as:
$ wget http://cdimage.ubuntu.com/daily-live/current/artful-desktop-amd64.iso
$ qemu-system-x86_64 -m 512 -boot d -cdrom artful-desktop-amd64.iso

But that works for me as seen in the attached video.
@Mathieu - can you elaborate how to trigger the missing key issue?

[Joshua Powers]

Hi! I am running Artful on my X1 Carbon Gen3.

I downloaded the Ubuntu Server Artful final beta and attempt to do an
install with the following qemu cli:

$ qemu-system-x86_64 -enable-kvm -cpu host -m 1024 -boot d -hda
vdisk.img -cdrom artful-server-amd64.iso -monitor stdio

Trying to use the arrow key at the first menu does not work and errors
with the unknown keycodes error. However, if I issue the `sendkey down`
command from the qemu CLI it works as expected.

So it is likely a wayland <-> SDL thing.
@Desktop Team could you take alook into this - the repro steps in c#2 are pretty easy I'd think but none of us would know where in the UI stack to look for.

Now the question is should the patch be dropped or wait for a fix from
upstream. I'm leaning towards the first option, since artful is about to
be released.

Actually, this bug would affect current 1.19-branch too since the
patches are backported there as well. You can test
ppa:canonical-x/x-staging to verify, which has xorg-server from current

It's worth noting that the xwayland patches in themselves won't make a

Ubuntu doesn't have any compositor change, it's standard GNOME 3.24 so
there is must be something wrong and it does make a difference without
implementing the protocole.

Note that reverting 0a448d133 does fix the issue

Can you try the attached patch (this is for testing purpose *only*) and

With this patch, if the compositor has no support for Xwayland keyboard
grab protocol as you said you haven't in Ubuntu, Xwayland won't set up
its grab handler at all.

Well, what this patch does is disabling any specific grab handler if the
Xwayland grab protocol is not available, by postponing the setup of
those handler until Xwayland can bind to the relevant interface as
advertised by the compositor.

If the compositor doesn't support the Xwayland grab protocol, then all
those routines are not "enabled" in Xwayland, I don't see how they could
break anything if not used...

Unfortunately, we cannot tell whether or not the compositor supports the
Xwayland grab protocol using something like weston-info because, for
security reasons, the compositor will (should) only advertiset he given
protocl to Xwayland alone and hide it to any other client.

So, if that patch makes no difference, it means that:

 - The Wayland compositor claim to support Xwayland grab protocol but is
buggy and doesn't send all key events as expected

 - Or the problem is completely unrelated to this patch.

So next step for you is to:

 - Check the actual patches applied to mutter in Ubuntu
 - Check what happens at the protocol level

To do so, yo can use the envvar WAYLAND_DEBUG prior to start gnome-shell
(which will spawn Xwayland) so that we can tell what globals are listed
in the wl_registry and see if "zwp_xwayland_keyboard_grab_manager_v1" is
one of them.

e.g., from a console:

  $ WAYLAND_DEBUG=1 dbus-run-session -- gnome-shell --display-server
--wayland |& tee ~/wayland-debug.log

The wl_registry globals will be listed at the beginning of the log so
that should be enough to tell if the compositor claims to be supporting
"zwp_xwayland_keyboard_grab_manager_v1".

Then, you can start qemu-kvm as usual and try to press the keys that do
not work, those will be captured in the log as well, so we can tell if
the compositor sends those key events to the client (Xwayland, in which
case the problem lies in Xwayland) or not (in which case the problem
lies in the compositor).

Please attach the "wayland-debug.log" to this bugzilla once you've
performed those tests (but make sure you don't type any sensitive data
in any application while the log is being captured as any key event will
be logged).

[Bug 1718719] Re: qemu can't capture keys properly under wayland

[Timo Aaltonen]

upstream can't reproduce this bug, so I wonder if the backport was
incomplete and it's fixed in the current release (1.20.8), could you
test again?

Title:
  qemu can't capture keys properly under wayland

Status in QEMU:
  New
Status in XServer:
  Unknown
Status in qemu package in Ubuntu:
  Confirmed
Status in xorg-server package in Ubuntu:
  Incomplete

Bug description:
  This appears to be different than the previous similar bugs; patches
  do look to be applied to use libinput in the wayland case. Still:

  unknown keycodes `(unnamed)', please report to qemu-devel@nongnu.org

  I am using qemu-system-x86                       1:2.10+dfsg-0ubuntu1
  on artful.

  Many key inputs work correctly, but at boot the system will not
  properly catch the arrow keys, the above error shows up immediately
  after hitting Esc (for instance) to get to the boot menu. Booting from
  CD onto a daily Ubuntu desktop image, I can't navigate the splash
  menu.

  The same works correctly through virt-manager (which uses spice
  AFAICT, but wayland tends to crash when running virt-manager), and
  things work if I switch my session to Xorg rather than wayland.

[Thomas Huth]

Is there still an issue left here for upstream QEMU?

[Thomas Huth]

Since there wasn't a reply to my question since more than half a year,
I'm assuming that this does not affect upstream QEMU anymore. Thus I'm
removing upstream QEMU from this ticket now.

** No longer affects: qemu
