Hi,
I have an Intel 915P Express Chipset MB. lspci tells me regarding
graphics:

"compatible controller: Intel Corporation 82915G/GV/910GL Express Chipset
Family Graphics Controller (rev 04)"

xorg.conf says that I'm using the VESA driver.

I have connected a cheapo webcam that usbview tells me is a Vimicro Corp
product. Installation of the spca5xx module results in the
/var/log/messages entry:

"/home/jwc/gspcav1-20060925/gspca_core.c: USB SPCA5XX camera
found.(ZC3XX)" along with other details.

lsmod tells me that modules videodev and gspca are installed.

So far so good, I guess. However when starting xawtv I get the message:

"v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*"
to type FontStruct"

and the accompanying xterm window is dark.. As far as I can tell the
device is recognized but there is no output. I'm stuck here and any help
would be appreciated.
Thanks, jwc

Usually, this is a bad idea. You should probably be using the i810
X module instead. Didn't you wonder why graphics were so slow and you
couldn't get a Vrefresh above 60 Hz?

It could be useful to know these other details.

Not good. Which version of which distro are you using? What's the
output of "uname -a"? The module you mentioned isn't part of the
vanilla 2.6.17.11 tree--where did you get it? Whatever font xawtv
wanted isn't installed. Install it. I've seen other people report
similar problems; groups.google knows more.

? Why would starting xawtv also generate an xterm window? Did you mean
"xawtv's window is solid black"? That might happen if xawtv is trying
to use XV to display video. The VESA module doesn't do XV (another
reason to use i810 if possible; mplayer/xine perform better if they can
use XV.) HTH anyway,

After my original post I did find that the microphone on the webcm works.
xawtv -hwscan gives:
/dev/video0: OK [ -device /dev/video0 ]
type : v4l
name : Generic Zc0305b
flags: capture
I added load v4l to the xorg.conf but that apparently made no change.

It might help to right-click in that window and try different capture
methods in the menu that comes up. Sometimes it works better with
"overlay", sometimes it works better with "grabdisplay".

I switched to the i810 driver and graphics is faster but xawtv still
shows a black window. In full screen mode I can see the messages about
muting and unmuting, etc. but still no pictures coming through.
