[Bug 1581687] Re: keyboard switching is broken in guest VM

[ChristianEhrhardt]

Hi,
thanks that video really helped to see your case.
First video 1:26 top right the shortcut is set to "None" I believe. Translate gives me "Никто" which does not fully match, but it seems unset at least. This is the setting that I set to Alt+ShiftL to work at all for me - maybe worth a try.

The second video with keymon is even better, I can see:
0:14 - Keys get to the Guest, Guest & Host switch language
>0.18 - Keys still get to the Guest but only the Host switches.

Thanks for the confirmation of this, but despite being non Desktop-
specific after the keycodes get to the guest then the virtualization
layer is kind of out of the equation. The Qemu around can't do more than
deliver the keys, and it seems they are there.

Unfortunately IMHO that means going back to file against whatever desktop components apply.
I'd keep qemu but set it to opinion (as it is a discussion about, but not likely in qemu) and stay subscribed personally, but since the keys get there as I said I don't see much qemu could do.

For me in Desktop environments it is always a bit hard to spot where to file the bug against.
I was following [1] and  [2] for the KDE case, one could do the same for the Xubunutu case.
The config for the Keyboard is via /usr/bin/systemsettings5 which is package systemsettings.
I'll set that now.
You could auto-add the right versions and such via `apport-collect 1581687`, maybe the KDE/Desktop folks would want that. Actually you should run that in Guest AND Host just to have all available.

Things I'd consider worth to try for you until there is a response from Desktop people:
- Set an explicit hotkey at "Main shortcuts" in the guest - if possible try a different one than on the Host (see my png)
- I have no reason why I assume that, but gut feeling tells me you could also try disabling the language selector in the Host to see if then the one in the guest suddenly works.

Let me know if these trial and errors turn out to be a workaround.
