* 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. |

All executable files in this directory are processed in shell expansion order. 00_*: Reserved for 00_header. 10_*: Native boot entries. 20_*: Third party apps (e.g. memtest86+). The number namespace in-between is configurable by system installer and/or administrator. For example, you can add an entry to boot another OS as 01_otheros, 11_otheros, etc, depending on the position you want it to occupy in the menu; and then adjust the default setting via /etc/default/grub.
