EDID

[Russell Shaw]

Hi,
I get a corrupt edid with get-edid. I've got a left-hand DVI LCD monitor and
a right-hand VGA CRT, both of which should work. I was using dual-head merged framebuffer
ok, but after a debian dist-upgrade, X now only does clone mode because it can't
configure the VGA CRT.


get-edid version 1.4.1

The EDID data should not be trusted as the VBE call failed
EDID claims 19 more blocks left
EDID blocks left is wrong.
Your EDID is probably invalid.
parse-edid: parse-edid version 1.4.1
parse-edid: EDID checksum failed - data is corrupt. Continuing anyway.
parse-edid: first bytes don't match EDID version 1 header
parse-edid: do not trust output (if any).
