virtualbox.org

In an Ubuntu guest, I got:

Virtualbox - Information

The virtual machine window is optimized to work in 32 bit color
mode but the virtual display is currently set to 16 bit.
Please open the display properties dialog of the guest OS and
select a 32 bit color mode, if it is available, for best possible
performance of the virtual video subsystem.
Note. Some operating systems, like OS/2, may actually work in
32 bit mode but report it as 24 bit (16 million colors). You may try
to select a different color mode to see if this message disappears
or you can simply disable the message now if you are sure the
required color mode (32 bit) is not available in the guest OS.

I read that I can solve this by adding to xorg.conf:

Code: Select all

Section "Screen"
        Identifier    "Default Screen"
        Device        "VirtualBox graphics card"
        Monitor       "Generic Monitor"
        DefaultDepth  24
        SubSection "Display"
                Depth         24
                Modes         "1280x800" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Or is there a better solution?

The best solution is to tick the "don't show this message again" checkbox, and make sure you installed GAs into the VM.

Oh and unless you are running a very old (not supported any longer) version of Ubuntu the xorg.conf has been depricated. Making one will probably cause the guest to not work. You should be leery of using out dated information off the Internet.
