Grub is loaded by the BIOS, it then loads the rest of itself, and it hands over to Linux when it quits. When you leave grub (by selecting a menu entry), control of the display is handed over to the Linux kernel, which will default to a text-mode display initially (in most cases). Later in the boot sequence (in most cases) the DRM drivers are loaded and kernel mode-setting kicks in, which alters the display to a higher resolution. If you want a more consistent display resolution, then grub would need to instruct the linux kernel to initialise the video display to match what it used. This is (I think) not impossible: certainly, prior to KMS, you could use a framebuffer console, and you could configure its resolution on the kernel command line. However, I'm not sure how that stuff interacts with the KMS stuff, so I'd advise not to bother. -- Jon Dowland
