--- Comment #41 from Zhiyi Zhang <zzhang at codeweavers.com> ---
You need to update to https://gitlab.freedesktop.org/xorg/driver/xf86-video-qxl
master. The version shipped by debian testing reports a XRandR provider with
only one output, which is a disconnected output and not connected to any CRTC.
So Wine incorrectly reports a detached monitor and not showing anything.

To test:
$ xrandr --listproviders

Good: Shows zero providers or a provider with more than one output
Providers: number : 1
Provider 0: id: 0x47 cap: 0x0 crtcs: 4 outputs: 4 associated providers: 0
name:qxl

Bad: Shows a provider with only one output. You can compare `xrandr --verbose`
and see the output count doesn't match.
Providers: number : 1
Provider 0: id: 0x8d cap: 0x0 crtcs: 1 outputs: 1 associated providers: 0
name:modesetting


The broken QXL driver is not officially shipped on most Linux distributions.
And I built a debian testing VM myself with all packages updated.
xserver-xorg-video-qxl version is 0.1.5-2+b1 on my VM, same as yours. But I see
you also installed a local linux-image-5.4.6, which probably triggered the
issue because debian testing ships a linux 5.3 kernel currently. I didn't go
further. 

All in all, being a testing version, I don't think it's worth polluting Wine
source with another workaround for this issue, so I recommend upgrading
xserver-xorg-video-qxl for the moment.
