Sun 15 May 2011 07:25:54 PM UTC, comment #1: Most of the things you guessed are wrong. For once GRUB doesn't have any processes. "auto" just uses the highest resolution reported by BIOS. 2.6.37 uses the graphics data passed by GRUB (even 2.6.32 does). "auto" isn't perfected and although it will be made better (by using EDID if found) it will still sometimes fail. Right resolution is sometimes unsupported by BIOS and so gfxpayload with this resolution is equivalent to gfxpayload=text. Furthermore failure of kms to switch mode (and going to purple color) is outside of GRUB scope and indicates a problem with KMS which should be able to switch from any to any supported mode. |

Now bzr version uses EDID which should solve the autodetecting issue. Also please avoid of plugging in the technical explanation if you have no idea of a subject. All your talk about "processes" which don't exist in GRUB only made your report longer and unreadable whereas concise and precise version would be simply "Video mode autodetected by GRUB isn't supported by monitor"
