Weird behavior of the VM shutdown dropdown

[Pedro Côrte-Real]

The VM window includes a shutdown button with a dropdown button next to it. I've noticed two weird things about it that seem like simple GTK bugs:

- The dropdown doesn't close just by clicking the dropdown button again
- All the items in the dropdown are greyed out as if they're not functional, but pressing any of them still works

This is how it looks for me (also 18.04).
Not greyed out and working fine (also open/close it)

It switches status when I switch guests - so if I select in the guest list one that is off the dropdown goes fully disabled - and when I come back to a running guest it is fine.

Could you check if that is in any way guest dependent with:
1. off guest
2. linux guest
3. win guest (I know from other bugs you have)

Maybe one of them has different Cpabilities announced or such triggering this case?

[Pedro Côrte-Real (pedrocr)]

I get this on all VMs if they're on. If they're off the dropdown is just disabled completely and I can't even open it (which makes sense). The greying out is probably a theming issue, you seem to be using a totally different one. I've attached a screenshot. Do you not get the inability to close the dropdown even with your theme?

[Christian Ehrhardt  (paelzer)]

No issue to close the dropdown at all - I can close it just fine.

My "Theme" is that I use KDE (and the default scheme there).
Let me spin up a default UI ...

[Pedro Côrte-Real (pedrocr)]

I assume it's still a theme as virt-manager didn't stop being a GTK app because you run KDE, or does it have a Qt replacement UI for KDE?

[Christian Ehrhardt  (paelzer)]

No in that POV it uses normal GTK.
The default theme is "Breeze" (package of the same name).

[Christian Ehrhardt  (paelzer)]

I wanted to test an 18.04.1 install anyway.
With a Desktop install and adding virt-manager in there I see exactly what you describe
- options greyed out
- still working if clicked
- issues to close the dropdown

Being a theme issue I'd file a bug task for them as well, as I'd now know what is wrong on the virt side.

[Christian Ehrhardt  (paelzer)]

So what do we know:
- Working in KDE + Breeze theme
- Broken in Gnome + Ambiance theme

I tried Gnome + Adwaita theme and it works fine then.

For the Desktop team steps to reproduce:
1. qemu-img create -f qcow2 /var/lib/libvirt/images/test.img 10M
2. apt install virt-manager libvirt-daemon-system
3. (relogin or "su -" to pick up group)
4. start virt-manager
5. define a guest based on existing image (the one created above)
6. start the guest

Now you'll see the dropdown showing these issues.
As mentioned, when switching to Adwaita the issue is gone.

[Pedro Côrte-Real (pedrocr)]

So you need me to open a new bug or is this one enough to track the ubuntu-themes issue?

[Christian Ehrhardt  (paelzer)]

This one is fine, if you look at the top I added a task for it.
This is a thing Launchpad does really well - avoid the proliferation and confusion of bugs affecting or being discussed in multiple packages.

I knew I had talked about it before, but couldn't find the bug last week - thanks Daniel for having a better bug navigation system!
