No TV after upgrade to .22 using PVR-350 TVOUT - help!

All -

I've upgraded to .22 and have everything working except I don't have TVOUT
capabilities any more (using the PVR-350).

This is CentOS 5.4 using video4lan - please see
http://www.gossamer-threads.com/lists/mythtv/users/406812#406812 for more
details and xorg.conf file.

-----
Here's the errors at the end of Xorg.0.log:

(II) IVTV: driver for ivtv framebuffer: PVR-350
(II) Primary Device is: PCI 00:02:0
(--) Chipset PVR-350 found
(EE) open /dev/fb0: No such file or directory
(EE) Screen 0 deleted because of no matching config section.
(II) UnloadModule: "ivtv"
(EE) Device(s) detected, but none match those in the config file.

Fatal server error:
no screens found
-----

It appears X is not configured correctly but I'm really not sure what I need
to change in the conf file, any guidance is appreciated.

Thanks!
Craig

If I'm not mistaken, ivtvfb.ko is missing from the atrpms video4lan rpm.

Run this command as root. If you get no output, the the framebuffer is
not installed.

find /lib/modules/`uname -r` -name ivtvfb.ko

If the framebuffer is there, you may be loading it incorrectly. What
does your /etc/modprobe.conf look like?

Simply upgrading to 0.22 wouldn't have broke X, so I take it you
upgraded something else too... One thing at a time, people!

Or, more sensibly:

$ /sbin/modinfo ivtvfb

I'd also suggest looking in dmesg for evidence of it having loaded, if
its there.

Other than some base packages that also updated the only change I made was
switching from ivtv-kmdl to video4linux-kmdl; which is probably the culprit.

I'll check into this now

I did find this thread on ivtv-users which discusses this issue:
http://www.gossamer-threads.com/lists/ivtv/users/40027 and claims to solve it
(at least for this user) with: http://linuxtv.org/hg/v4l-dvb/rev/e66ace4b4a61

Unfortunately this is beyond my abilities, hopefully some of the more
"technically skilled and talented" on this list can provide some direction.

Thanks!
Craig

Craig, it's probably best to post something on ivtv-users, as this is
not a mythtv issue and the ivtv-users list will probably produce
better results.

You may want to look for a new video out solution. PVR-350 TVOUT
support was dropped yesterday in trunk.
