[Openchrome-users] SP-13000, TV-out and driver version

[apan loco]

Hi,

I have realised that I need the openchrome driver due to the xvmc support,
but really don't know what driver i currently have. I use Ubuntu Dapper and
Xorg.log shows this:

--- Xorg.log ---

(II) Loading /usr/lib/xorg/modules/drivers/via_drv.so
(II) Module via: vendor="X.Org Foundation"
        compiled for 4.3.99.902, module version = 0.1.33

--- End Xorg.log ---

My guess would be that I'm either using Via's own released driver or the
openchrome since Xvmc is loaded and actually seems to work in MythTV. I am
wondering however if you think a newer version (if it exists at all) of the
driver could solve my "problems" with TV-out. TV-out does work but really
doesn't fill the whole screen, mostly leaves black stripes to left/right but
also some top/down. I have tried some different "Modes" under "Display", but
none is perfect. I am using PAL, btw, and the Mode "720x576Noscale" makes
the screen go crazy when in 24 bit mode, but works quite nice in 16 bit
mode, but I am concerned about picture quality (even though I can't see a
difference :). This is my relevant Xorg.conf if someone is kind enough to
help:

Section "Screen"
        Identifier "Screen0"
        Device     "VideocardViaTv"
        Monitor    "MonitorTv"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
#               Modes    "800x600"
#               Modes    "640x480"
                Modes    "1024x768"
#               Modes    "720x576"
#               Modes    "720x576Over"
#               Modes    "720x576Noscale"
        EndSubSection
#       SubSection "Display"
#               Depth     16
#               Modes    "1280x1024" "1280x960" "1152x864" "1024x768"
"800x600" "640x480"
#               Modes    "720x576"
#               Modes    "720x576Noscale"
#       EndSubSection
EndSection

Yes, I am currently using "1024x768" since the picture is centered in
contrast to "720x576". I don't know the difference though except for that as
it seems to take up equal amount of space on the TV (scaled?) which kind of
surprised me. Perhaps it more or less only slows down the computer?

This is a bit more maybe of relevance:
Section "Device"
        Identifier  "VideocardViaTv"
        Driver      "via"
        VendorName  "Via"
        BoardName   "cle266"
        Option  "PciRetry" "true"
        Option      "TVType" "PAL"
        Option      "TVOutput" "S-Video"
        Option      "TVDeflicker" "1"
        Option      "TVDotCrawl"        "false"
        Option       "EnableAGPDMA" "true"
EndSection
...
# I have more or less no idea where the HorizSync/VertRefresh values come
from, and the ModeLines are more or less a mystery :)
Section "Monitor"
        Identifier   "MonitorTv"
        VendorName   ""
        ModelName    "TV-PAL"
        HorizSync    24.0 - 80.0
        VertRefresh  50.0 - 75.0
        Option      "nodpms"
        Option      "noddc"
# Set for 4:3 display
#       DisplaySize     300 225
# Set for 16:9 display
        DisplaySize     400 225

I seem to need TVDeflicker in some modes so it's on mostly.
I'm almost there. Could a new driver solve my problems? Does anyone have
some advice?
