According to the documentation, use of the
vga= kernel parameter is deprecated as of GRUB2. The fact that some newer kernels don't seem to support it anymore on certain adapters is of no concern as the graphics card I have is seven to eight years old.
The problem now is that I would like to use a higher resolution text mode, such as 80x50 instead of the default 80x25 characters. Apparently all graphics (VBE/VESA) modes are out of the question for this graphics card (ATI Rage XL) - the list of available modes only shows
80x60 but looks horrible, so I'd like to go with
I've seen 80x50 and 80x60 working after getting the list of available modes whenever the default mode wasn't supported (with the default commented out
GRUB_TERMINAL=console) and I was prompted to choose.
How can I set the mode, if I'm not supposed to set it on the kernel command line and every use of
GRUB_GFXMODE (with or without preloading
vbe module) and
GRUB_GFXPAYLOAD_LINUX=keep fails? Fails as in: screen stays blank because it's an invalid graphics mode for the card I have in this machine?
My idea would be to pass
nomodeset to the kernel still, but the boot loader would then still have to set the graphics mode. And I can't see any options other than the
vga= kernel parameter for doing that.
videotest commands on the GRUB2 console will blank the screen and then the screen switches to sleep mode after claiming there is no video input.
videoinfo show a few available modes other than the above mentioned, but there is no mentioning of where this should be set. Also, when passing
nomodeset) on the kernel command line, I see a very brief warning about it being deprecated, but it's too long to read completely - and the output doesn't appear in
