@Thomas - there is a leftover task here and I've filed [1] for it in the new
tracker.
What is the right state to move this bug here into now?

Looking at the comments, it seems to me that this was an issue in VTE
that got fixed. Is there still anything left to do for upstream QEMU
here?

Thanks Ken!
I verified it and the new version indeed fixes the issue in focal.

As Vte-upstream long term would want to get rid of this implementation
style Christian Persch provided a qemu patch [1]. That is too much UI
for me to really have an in-depth opinion, but I can say that it builds
and input works fine with it.
I suggested on [2] to send it to qemu-devel, but in

Thank you for investigating this. I would bisect QEMU, but wouldn't
investigate its libraries. Consequently, I would never find the cause of
this problem.
For now, I am using -monitor telnet:127.0.0.1:5,server,nowait to
have access to the monitor on QEMU guests.

I'm not sure how many of you are tracking the Vte bug [1] so here a
summary of the latest insight from there.
- Short term it seems that new behavior will be reverted in Vte 0.60.1.
- Long term the Vte devs might want to deprecate no-pty use cases or at least
better understand why apps use it
same seems to happen on Fedora 32.

I'm not really a UI guy, so I was checking what I might have lost by disabling
VTE and found the very old [1]. That list of features really seems to make
disabling VTE not an real option:
"It's also screen reader accessible, supports copy/paste, proper scrolling and
most of the other
For a bit of reverse-confirmation of the findings so far.
If I build qemu without VTE, like (configure)
GTK support yes (3.24.14)
VTE support no
It works, due to the fallback implemented by [1][2].
But obviously without all the VTE features, I'd prefer a more fine grained fix
than
Thank you Egmont for the bug for VTE in the gnome tracker!
Graphics isn't something I'm usually at home - the related qemu code is
mostly in ui/gtk.c per Maintainers file Gerd Hoffmann is the expert. I

Thanks for this investigation so far!
We've opened an upstream VTE issue at
https://gitlab.gnome.org/GNOME/vte/issues/222 .
We'd appreciate if QEMU developers joined us there. Apparently QEMU uses
the "commit" signal in a way that it was not meant to be used, and thus
it's unclear what the best
Last commit mentioning VTE is a while ago:
6415994 Thu Oct 11 17:30:39 2018 +0200 gtk: Don't vte_terminal_set_encoding()
on new VTE versions
I built head of qemu against head of vte - to check if I even need to look for
existing fixes.
=> That still fails, so it is probably time for a bug
FYI: Since this affects qemu (and VTE) git head I added an upstream-qemu
task to the bug.

I retried with the latest qemu as I recently did some misc fixes in the form of

But with that it fails as well.

This still worked in Eoan, I double checked and it indeed does.
So it is not the change to GTK which I assumed first to be relate.
To ease repro of the case, this can be seen even if "ssh -XY" into
Eoan/Focal containers.

ok CTL+ALT+2 (without shift) is working well to switch - also the GTK UI
has a menu to switch which works as well. But on all of those tries no
way to enter to the monitor.

Hi Leonardo,
I first ran something in libvirt as usual, and I got monitor access through
libvirt as usual.
For example:
$ virsh qemu-monitor-command focal3 --pretty '{"execute":"query-block"}'
Then I started a most basic qemu to get the usual UI.
$ qemu-system-x86_64 -enable-kvm --drive
** Summary changed:
