I had this "issue" not only with Bodhi, but also with other Ubuntu derivates. When installing Bodhi (or Xubuntu or .........) in Virtual Box, everything runs smoothly. But when performing the actual installation on my system I noticed a huge difference and especially in the field of graphical support.
I had Mint Xfce installed. In VB I installed Xubuntu. No problems so far. When I wiped my SDD drive in order to install Xubuntu, my system suffered from a blinking, flickering screen. Even after installing the latest graphic drivers for my Intel and Nvidia GPU's (I have an hybrid system, 2 GPU's). With Linux Mint I had no issues whatsoever with the graphic drivers and screen resolutions. I would say that Mint Xfce and Xubuntu is using the same Windows Manager and desktop environment which should give no problems... It did.
I experience the same with Bodhi. In VB no issues, but an actual install let my whole system freeze without any warning or reason. never found out what caused this but is annoying as hell.
Does anyone has a valid reason/explanation why there is such a huge difference between an actual install and a VB install? I now that VB is using resources of the host it runs on but that can not be the main reason for those differences?
