VirtualBox gust screen resolution doesn't work well under i3wm, sometime it get stuck at some strange resolution.

This script can fix the window size.

From the guest side, we use VBoxManage to tell the guest that a new resolution is available.

Window is made floating, then the border is removed (it count as width/height), then the window is resized.

Brother MFC-J480DW cuts off top margin

In Linux, my Brother MFC-J480DW cuts off top margin when used with A4 paper, even if all settings are set to A4.

To make it work, I had to edit /opt/brother/Printers/mfcj480dw/inf/brmfcj480dwrc file (that's the path in Gentoo, it could be different in other distributions).

And change:

PaperType=Letter
