Dropdown window from taskbar doesn't show

Hi,

I created a new Standalone Qube to run some software which need to modify various places and system settings. The standalone Qube is made by cloning the debian-12-xfce template.

The installation went smoothly, and the software could run. The problem is, normally, on a Debian, the software would open a dropdown menu from the Xfce taskbar, on launch. However, probably because of QubesOS’s virtualization of X11, that window wouldn’t appear at all.

Is there any way to make it appear, or, alternatively, run the standalone Qube without X11 virtualization?

Any help is appreciated.

I changed the virtualization mode to HVM and changed kernel to “provided by qube”, and then the window could appear.

Don’t know exactly why. If changing virtualization mode helps, then the problem might not be due to X11 virtualization.

OK, now after changing back to PVH, the software suddenly started working correctly. Thus, perhaps it’s because something happened when it was just installed. I am still curious to know why although it’s resolved.
