[Openchrome-users] Problems with openchrome 0.3.1 on Epia EN15000G

[matt Jarvis]

I have an Epia EN15000G with CX700 chipset running minimyth, which was
working correctly using the 0.2.906 release. Having upgraded to the latest
minimyth which includes 0.3.1, I'm having some issues getting Xorg to work
properly. I'm using DVI to HDMI, through a surround sound receiver and via
HDMI from there into my TV.

With the 0.2.906 release, I have the following in my xorg.conf :

Section "Monitor"
    Identifier  "Monitor1"
    HorizSync 30.0-50.0
    VertRefresh 50.0-50.0
EndSection

Section "Device"
    Identifier  "Device_openchrome"
    Driver      "openchrome"
    Option      "EnableAGPDMA"        "true"
    Option      "ActiveDevice"        "DFP"
    Option      "VBEModes"            "true"
    Option      "SWCursor"            "true"
EndSection

Section "Screen"
    Identifier  "Screen1"
    Device      "Device_openchrome"
    Monitor     "Monitor1"
    DefaultDepth 24

    Subsection "Display"
        Depth       24
        Virtual     1280 720
        ViewPort    0 0
        Modes       "1280x720"
    EndSubsection
EndSection

With this release, xrandr -q shows :

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 720, maximum 1280 x 720

   720x480         0.0
   640x480         0.0

With the 0.3.1 release and this xorg.conf, I initially get a Video Not
Supported message from my TV.

xrandr -q shows :

Screen 0: minimum 320 x 200, current 1280 x 720, maximum 2047 x 2047

   1440x288       50.1

   1440x240       60.1
   640x480        85.0     75.0     72.8     59.9
   720x400        70.1

If I manually switch the refresh rate to 60 using xrandr, I now get the
mythtv gui perfectly, but video playback using Xv is just a blue screen but
with the correct audio. I also get a log message saying :

(EE) CHROME(0): [Xv] Port 0: Bandwidth is insufficient. Check bios memory
settings.

I've attached my xorg.log which shows boot up, switching the refresh rate
and attempting to play video.

If anyone can help point me in the right direction to get the correct
refresh rate on boot up, and with getting xv playback working again it
would be much appreciated :)
