I used to suggest this, but it generally doesn't work any more. It
isn't a normal kernel parameter:
vga= [BOOT,X86-32] Select a particular video mode
See Documentation/x86/boot.txt and
Documentation/svga.txt.
Use vga=ask for menu.
This is actually a boot loader parameter; the value is
passed to the kernel using a special protocol.
GRUB 2 documentation says:
On x86 systems, the kernel will be booted using the 32-bit boot
protocol. Note that this means that the `vga=' boot option will
not work; if you want to set a special video mode, you will need
to use GRUB commands such as `set gfxpayload=1024x768' or `set
gfxpayload=keep' (to keep the same mode as used in GRUB) instead.
GRUB can automatically detect some uses of `vga=' and translate
them to appropriate settings of `gfxpayload'.
