Public bug reported:
I am creating a new computer platforms. It provides two video sources:
an Intel i915 DisplayPort and an AST2500 VGA. The i915 also provides
HDMI, but it is disconnected/disabled.
EXPECTED BEHAVIOR: Video is presented through the AST2500 to VGA and the
i915 to DisplayPort, mergine the displays to a unified layout when a
layout is provided to xorg.
ACTUAL BEHAVIOR: Both monitors present a purple background at login, but
the VGA monitor is quickly disabled at login.
When I had a problem with these video sources under Windows the Intel
team provided me a "Switchable Graphics" BIOS module. It resolved the
issue there. My BIOS settings define "Switchable Graphics" as the
Primary Display.
When I set the BIOS to use the ast2500 as the only display source the
system works as intended. I mention this to confirm the ast2500 and
kernel can display video even if the ast2500 won't display video
alongside the i915.
