I have a VM machine running ubuntu 14.04 (guest) on a Win7 host. I currently have the resolution of the server set to 1024*768 by adding this
GRUB_CMDLINE_LINUX_DEFAULT="splash xvga=1024x768x24" GRUB_GFXMODE=1024x768x24
However I cannot get higher resolutions. When I set for example 1200*800 it resets to 640*480. I have allocated 128MB video memory.
Can I get to higher resolutions?
