           Summary: HDMI-A-1 Does not work if disconnected at power-up
                    (But claims it does)
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: Russ.Dill@gmail.com


I have an "ATI Mobility Radeon X1600" (ChipID = 0x71c5). It has four outputs,
VGA-1, LVDS-1, HDMI-A-1, and SVIDEO-1.

I'm running 2.6.37 final (Ubuntu 2.6.37-12.26) and the Ubuntu xorg edgers
1:6.13.99+git20110110.0e432dff-0ubuntu0sarvatt version of
xserver-xorg-video-ati. I'm pretty sure this has something to do with a display
being plugged into VGA-1 as well.

I originally thought this had to do with being connected at powerup, but it
really has to do with it breaking after powerup. The attached dmesg and
xorg.log is from:

powerup laptop with no external displays connected
plug laptop into docking station. LVDS-1 turns off, HDMI-A-1 and VGA-1 turn on
suspend laptop
wake laptop, VGA-1 turns on, HDMI-A-1 does not

Does the LVDS come on when you resume?  X may be getting confused and enabling
the wrong displays on resume (LVDS+VGA rather than VGA+HDMI) since all are
attached.  Can you manually reconfigure things using xrandr after resume?

xrandr shows LVDS as being off and HDMI as being on. Manually fussing with
xrandr doesn't change anything, but I can turn the LVDS display on and off.
However, if I try to turn all three displays on at a time, X segfaults (or at
least the last time I tried it did).

Can you attach the output of 'xrandr --verbose' before and after resume?  Also,
if you get a segfault, can you get a backtrace and attach it here?

The xorg crashing thing is no longer true, its been fixed at some point.
gnome-display-properties still gets confused and thinks it successfully
configured all three, but there is no crash. (and closing and re-opening
gnome-display-properties changes it back to only showing two displays enabled.

Does a dpms cycle help?
xset dpms force off

Does restarting X help?

How about forcing a mode change? e.g.,
xrandr --output HDMI-0 --mode 1680x1050

Nope (but causes the VGA-0 monitor to flash off and on)

Nope

So there is a DVI port on the dock and an hdmi port on the laptop.  It's likely
they share the same encoder and there may some gpio magic involved in switching
between them.  I don't see any router info in the vbios, so it's likely to be a
system specific thing.  Maybe some acpi method?  When the hdmi port isn't
working, does the DVI port work or vice versa?

Just a few followups. It doesn't seem to be related to the docking station
switching. The problem occurs even without the docking port.

Additionally, if I plug an HDMI cable into the laptop while the docking station
is plugged in, the monitor is not detected at all. Where-as after I resume and
have a problem, the monitor is detected, it just doesn't get sync. So the
docking station switching disables the port "more" than the resume problem.

- radeon.modeset=0 displays the same problem
- vista-x32 works correctly

This is consistent with the gpio controlled data and ddc routing that I suspect
is happening.  There's probably a small mux which routes the ddc/hdp lines (for
detection and edid) and the data lines (for the actual video signal) between
the HDMI port on the laptop and the DVI port on the docking station.  When you
dock, the acpi docking method probably calls some other method which switches
the mux to the other connector.  The same thing probably happens on undock. 
The question is, is this handled by an acpi method or some platform specific
gpio/i2c setup.  Newer radeon-based laptops that use a mux like this have a
special entry in the vbios object table that describes the mux.  Unfortunately,
your system doesn't have this, so it's probably some system-specific
configuration.  When you suspend, the mux loses power and goes into some
undefined state on resume the signals are not routed correctly since the mux
state is wrong.

Russ Dill, Ubuntu Natty Narwhal reached EOL on October 28, 2012. For more on
this, please see https://wiki.ubuntu.com/Releases.

If this is reproducible with a supported release, it will help immensely if you
filed a new report with Ubuntu by ensuring you have the package xdiagnose
installed, and that you click the Yes button for attaching additional debugging
information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.
