Xorg can not be brought up using Vga Port Of Hp Monitor With On-Board Graphics On Ultra 20 M2. (Doc ID 1351929.1)

Last updated on JULY 29, 2016

Applies to:

Solaris Operating System - Version 10 10/08 U6 and later
Information in this document applies to any platform.

Symptoms


One replaced the broken Sun monitor with a HP ZR24w monitor. He wished to use the VGA port of the on-board graphics card on Ultra 20, M2 and Xorg could not be brought up in this configuration.

By reviewing the Xorg.0.log, the error encountered was "(EE) RADEON(0): EDID Version 1.4 not yet supported
(II) RADEON(0): DDC Type: 2, Detected Type: 0"

Changes

System worked with a nVideo card/Sun monitor. One took this card out to force the Ultra 20 M2 to use VGA port from the on-board graphics card with the new HP monitor.  The Xorg could not be brought up since then.
