/dev/video0
by Alain PORTAL
Hi,
Can somebody tell me how is created this device?
When I'm connecting my webcam, nothing happends but in messages.log:
kernel: usb 4-1.4: USB disconnect, address 3
kernel: usb 4-1.4: new full speed USB device using uhci_hcd and address 4
kernel: usb 4-1.4: not running at top speed; connect to a high speed hub
kernel: usb 4-1.4: configuration #1 chosen from 1 choice
kernel: 4:3:1: cannot set freq 0 to ep 0x86
kernel: 4:3:2: cannot set freq 0 to ep 0x86
When I load the module ("modprobe gspca"), new in messages.log:
kernel: usbcore: registered new driver gspca
kernel: /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: gspca driver
01.00.04
And always no /dev/video0
I create it ("mknod /dev/video0 c 81 0; chmod go+wr /dev/video0"), verify
[root@lns-bzn-59-82-252-142-2 ~]# ls -l /dev/video0
crw-rw-rw- 1 root root 81, 0 nov 16 01:45 /dev/video0
and run an application
[root@lns-bzn-59-82-252-142-2 ~]# xawtv
This is xawtv-3.95, running on Linux/i686 (2.6.18-1.2239.fc5)
WARNING: v4l-conf is compiled without DGA support.
can't open /dev/video0: No such device
v4l-conf had some trouble, trying to continue anyway

v4l2: open /dev/video0: Aucun périphérique de ce type

You might want to consider instead buying an internet webcam such as the
Dlink DCS-900 or DCS-G900. Works over a network cable, can be
individually addressed, and you can even do so remotely, if you have
DYNDNS or the equivalent or a static IP address.
The cost is a little higher than the cheap cameras, but the quality is
very good and the advantages are worth it.

Hi Alexander,
This an age old bug/feature of Gnome. It occurs when there is a program
update or software install that adds or repopulates the Gnome menus. If
you don't run Gnome while getting updates or log out and in (of Gnome)
after getting updates or installing programs that add menu entries, your
menus should refresh without scrolling.

Printing header in Firefox -
by Bob Goodwin
I often print pages that I bind and save from firefox. It is supposed
to print the Title and URL as a header on each page however all I ever
get is the very bottom of the letters, not enough to even guess at the
words.
I have tried all the available settings but with no success. Print
Preview shows the header perfectly but unfortunately the printed page
does not.
This problem is peculiar to Firefox, Openoffice prints headers and
footers without a problem. I am running Firefox version 1.5.0.9 and FC6
updated this morning.
Any thoughts on what I might do to fix this?
Thanks.

Nautilus not working propelvy with images
by Andrea Mastellone
Hi everyone,
what is wrong that Nautilus can not handle correctly images, especially
in the png format ?
I have a FC6, regulary updated.
A little example will explain my situation: if you, in a Nautilus
window, go to "Backgrounds and emblems" from Edit Menu, in the section
"Patterns" you will see a list of png thumbnails of the patterns. My
Nautilus doet not show anything :( (if I launch it as root, it works
again, however !).
I have reinstalled gnome, nautilus, ImageMagick, and libpng without any
result :(
What is the library that handles this situations ? Perhaps it works only
as root...
Thanks you in advance,
Andrea

National-character conversion
by Albert A. Modderkolk
Is there a tool that converts, for example, the u-umlaut into the ü
symbol? Would be nice if it could convert any national-language
characters.
Thanks and regards, Albert
