Hildon-Desktop doesn't seem to handle VirtualBox changing window size.

[android-808]

After installing guest additions, prior to reboot I was able to resize the VirtualBox window and Hildon would attempt to match the new size.

• Desktop background/panel etc doesn't change, becomes a rectangle on bottom left of window surrounded by black screen/blank space.
• Event detection is now based on the new window size, so you still click top left of screen to open menu, although the visual button is as described above.
• New windows such as the power button screen (Machine>ACPI Shutdown) display taking full width of the screen but vertically they appear relative to the panel mentioned in the bottom left.
• Event detection of new window if based on the new window size, so again its guess work.

After reboot resizing VirtualBox window works as if guest additions not installed, ie screen stays same size but is centered in blank space.

On a positive note, shared clipboard works.

I was not aware of the fact that hildon-desktop handled resizing of the screen (well) at all. Did it use to work?

And does a reboot fix the issue if you keep the screen of the same size?

I had a vbox error pop up today having restarted the machine a few times regarding a xrandr failure. I have since installed x11-xserver-utils so that xrandr is now present. Still doesn't react to resize since that initial install. You can however run xrandr --output Virtual1 --mode 1280x960 to replicate the scenario above.

My reason for testing was to see if we can get VirtualBox to resize the window to accurately simulate device screen size/resolution to allow the user to test app appearance.

If you resize upwards and then change it back it still stays messed up.

I actually experienced some of this resizing mechanism when using a external display which it does handle, support comes from xrandr and such. It does get treated as a huge single display because of the display extending causing some issues with how far you can see, edge being cut off, etc Fiddled a while ago through.
