[mythtv-users] Wierd problems on loading ivtv module on startup

[Matt Hannan]

The fb0 can be found with:
# cat /var/log/messages |grep "iTVC15 TV out"

Should yield something like:
Feb 7 21:17:39 htpc kernel: fb0: iTVC15 TV out frame buffer device

If that search gives you something else, then change fb0 in your
XF86Conig to whatever is reported by the above.

I am sure that you solved this by now, but I am trying to get my PVR-350
TV-Out to work and so am fresh from the Jarod and searching for answers
myself.

Thanks for getting back to me.

If I recall, this is exactly what the pertinant section of the
XF86Config file says: Section "Device"
        Identifier  "Hauppauge PVR 350 iTVC15 Framebuffer"
        Driver      "fbdev"

        ### change fb0 to whatever your card grabbed
        Option      "fbdev" "/dev/fb0"

        BusID "0:0x0b:0"
EndSection

I copied it straight from Jarod's tutorial and really doubt I would have
changed the Driver info (in fact, I am certain I did not as I grepped
the file to find instances of "fb0" and only posted those lines).  I
will try a reboot and do an lsmod, but I know it is ivtv not getting
loaded at startup, and I suspect due to that error (Feb 17 08:15:00
localhost
modprobe: modprobe: Can't locate module fb0).  No idea why it is looking
for a module called fb0, and when I grepped /etc/modules.conf for fb,
all I saw was "add above ivtv ivtv-fb" (w/o quotes).  So maybe I need to
search the whole system for an instance of fb0 in a config file?  Not
sure, but this is really wierd, and something that I know is probably
easily fixable, but perhaps out of my expertise.

Any help would be greatly appreciated!

I think your problem might be with your XF86Config file.  The line prior
to the one you mention should be:

    Driver      "fbdev"

is it?  if it says fb0 instead of fbdev then that is your problem.

Basically (not sure why) somewhere you are trying to modprobe fb0
instead of something else... which will give you an error unless you
have a module named fb0.o

Another hint that might help pinpoint the problem is to do a lsmod and
see what has been loaded. and what hasn't.

hope this helped.
