I got a webcam today. As a first step to finding something to do with it is
making sure it works, so I installed xawtv (and all the stuff it drags in).
One member of its entourage is 'v4l-conf'. It uses DGA by default,
framebuffer if so instructed, and the console driver on mklinux. That last
is a no-go obviously. DGA:
eben@pc:~$ v4l-conf -d :0
v4l-conf: using X11 display :0
dga: version 2.0
X Error of failed request: XF86DGANoDirectVideoMode
Major opcode of failed request: 128 (XFree86-DGA)
Minor opcode of failed request: 1 (XF86DGAGetVideoLL)
Serial number of failed request: 13
Current serial number in output stream: 13
When I went looking for [dD][gG][aA] in xorg.conf, I found this:
Section "Module"
SubSection "extmod" # don't initialise the DGA extension
Option "omit xfree86-dga" # the nvidia driver doesn't support it,
EndSubSection # so why use the RAM?
EndSection
That would suck. Is that really the case?
When I tell it to use the framebuffer:
eben@pc:~$ v4l-conf -f
ioctl VT_GETSTATE: Invalid argument
How do I enable fb? Only by recompiling the kernel?
I've already got a VM set up running 64-bit Ubuntu. Sounds like the asiest
thing might be to use the webcam only in there. That is, unless there are
other tools that depend on neither fb nor DGA. Are there?
