I'm using VirtualBox: host OS Win7, guest OS Ubuntu 9.10.
When I start the VM, there is a warning "This virtual machine windown is optimized to work in 32 bit color mode, but the color quality of the virtual display is currently set to 16 bit."
Trawling through forums, I've found recommendations to add a line to the /etc/X11/xorg.conf file, namely the line "Driver "vboxvideo"" which seems to solve the problem. However, this is for older versions of Ubuntu. The poster states "However, later versions of Ubuntu, like 8.10 and the new 9.04, no longer use that file for initial settings. You can still use it to change a few settings, but most is done by HAL"
So the question is, in Ubuntu 9.10 what is the equivalent?
