Description Stelian Pop 2000-07-16 11:46:37 EDT

My Iiyama vision master 403 is incorrectly DDC probed by the installer:
31.5KHz/60Hz
(instead of 27-96 / 50-160 correct values).

Comment 1 Matt Wilson 2000-07-17 15:36:19 EDT

What is the 7 character ID for the monitor (it would say something like "DDC
probed monitor IVM1234")

Comment 2 Stelian Pop 2000-07-18 05:15:52 EDT

Where can I found this information ? (is there some file to look into, like an
/etc/sysconfig/something,
or a program to launch).

Or do I need to go through the whole install process once again?

Comment 3 Glen Foster 2000-07-18 16:37:08 EDT

This defect is considered MUST-FIX for Winston Beta-5

Comment 5 Stelian Pop 2000-07-18 17:24:01 EDT

I don't know if this is enough, but running the
WinstonBeta3CD1:/RedHat/instimage/usr/sbin/ddcprobe binary on a RedHat 6.2
system gives me the following (see the attachment).

The ___ffff ID seems to be the same thing I saw when installing the beta (quite
sure)...

Is this enough information for you or not ?

Comment 6 Matt Wilson 2000-07-18 18:41:00 EDT

Fixed in CVS.

Comment 7 Stelian Pop 2000-08-18 14:59:01 EDT

Well, it doesn't seem so...

This time my monitor is under: DDC Probed Monitor -> Unsupported Monitor (31.5
kHz / 60 Hz).

I'm reopening the bug.

Stelian.

Comment 8 Matt Wilson 2000-08-18 15:02:14 EDT

ddcprobe didn't get a reply from the monitor, this may be due to a kvm switch, a
loose cable, or the phase of the moon.

Comment 9 Stelian Pop 2000-08-18 15:08:35 EDT

Should I try the installer again ?

Comment 10 Matt Wilson 2000-08-18 15:10:46 EDT

I'd just install and run the "ddcprobe" command off the CD in
RedHat/instimage/usr/sbin and see what pops out

Comment 12 Stelian Pop 2000-08-18 15:37:27 EDT

I suppose you are meaning the usr/sbin/ddcprobe from the iso image
/mnt/cdrom/RedHat/base/stage2.img ? :)

Done, output seems correct to me :(

Stelian.

Comment 13 Stelian Pop 2000-08-18 15:45:13 EDT

Oops, after reading my own attachement it seems that ddcprobe didn't worked so
well :)

But I'm sure that this worked 1 second before I send the output to the file to
attach.

I tried again but each time I get the 'EDID read failed, returned empty data'.

Maybe this works only one time, when the is booted ? 

Anyway, seems that your theory on the moon phase is correct...

Stelian.
