It will interfere with the clipboard if both Xpra and VirtualBox try to
synchronize it, this is known to cause system crashes.

You can resize it using the regular desktop tools: xrandr and its gui
equivalents.
The default size of the desktop mode should be 1920x1080.

Changing the default is documented here:
https://xpra.org/trac/wiki/Desktop

For completeness, here are 2 more options:
* not recommended: change the xorg configuration and/or the "xvfb"
command line option
* run the server using:
XPRA_DEFAULT_VFB_RESOLUTION=1280x1024 xpra start-desktop --start=fluxbox

Note: the resolution chosen must be supported by the server, you use
"xrandr" to get the full list.

> Also, I’ve tried to use different desktops (kde, gnome and unity), and to disconnect my physical second screen from my laptop. If I start a simple program as xterm, there are no problems, it’s the proper size. However, doing so with a desktop, it just won’t work.
I don't understand what "won't work" in this case.

> Any suggestions on this? I’ve gone through all the xpra manual, but I might have overlooked a setting. Otherwise I don’t know if it can be a bug maybe…
The wiki tends to have better documentation than the man page these days.

Thanks.
The title of your email refers to a crash, but I don't see any details
on that.

Cheers
