Description
VirtualBox calculates the required video memory in UICommon::requiredVideoMemory(). Basically, it calculates memory for 1 surface for Linux guests, and for 2 or 3 surfaces for Windows guests (plus some extra). Is this calculation still correct for the new graphics controllers (VBoxSVGA, VMSVGA)?
I'm asking because a forum user seemed to have problems with a Linux guest switching to 1920x1080 and the VirtualBox default of 16 MB VRAM would IMHO be enough memory, if the factor of 1 was still valid (~ 9 MB). Because this was one of multiple cases in the previous years, it made me wonder if the calculation is still correct.
