Current Kernel is 3.14.9-200 x86_64. This is a multihead setup; i915 and
NV96 video cards (displays HMDI2 = i915 and NV96 DVI-I-1 and VGA-2 [both
X233H Acer]). kernel bootmenu is presented from DVI-I-1, after kernel
selection, LUKS prompt appears on HMDI2 and DVI-I-1 is disconnected. In
multi-user env HDMI2 and VGA-2 are active and dmesg shows edid complaint
about DVI-I-1. /usr/bin/edid-decode complains about edid block for both
NV96 displays DVI and VGA but for whatever reason DVI is only one
disconnected.
So far searches in various forum threads and bugzilla suggest buggy DVI
edid problems been around for awhile. The DVI edid block error follows
DVI connector, meaning, moving DVI cable to monitor previously with
label VGA-2 will produce same edid message. I haven't found complete
instructions to build CustomEdid yet, that seems the way to go since
commandline settings like drm_edid_strict, video=DVI-I-1:e are ignored.
Pointers to documentation to build customedid or kernel commandline to
disable DVI edid checking will be greatly appreciated.
Thanks in advance.
