* grub-core/video/i386/pc/vbe.c (grub_vbe_bios_get_flat_panel_info): New function. (grub_vbe_bios_get_ddc_capabilities): Likewise. (grub_vbe_bios_read_edid): Likewise. (grub_vbe_edid_checksum): Likewise. (grub_vbe_get_preferred_mode): Likewise. Try EDID followed by the Flat Panel extension, in line with the X.org VESA driver. (grub_video_vbe_setup): When the mode is "auto", try to get the preferred mode from VBE, and use the largest mode that is no larger than the preferred mode (some BIOSes expose a preferred mode that is not in their mode list!). If this fails, fall back to 640x480 as a safe conservative choice. * include/grub/i386/pc/vbe.h (struct grub_vbe_flat_panel_info): New structure. (struct grub_vbe_edid_info): Likewise. (grub_vbe_bios_get_flat_panel_info): Add prototype. (grub_vbe_bios_get_ddc_capabilities): Likewise. (grub_vbe_bios_read_edid): Likewise. * util/grub.d/00_header.in (GRUB_GFXMODE): Default to "auto". This is more appropriate on a wider range of platforms than 640x480.
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. Please look at the GRUB Wiki <http://grub.enbug.org> for testing procedures. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
