I never tested a webcam since it depends on the system and I don't have one to setup.
It could have been an update that messed it up.
Also could have been an update on his machine that enabled it.

The only other thing I think it could be it the Privileges.
Menu --> Users and Groups --> Unlock --> click correct user name --> Click Properties --> Users Privileges tab.
Check Capture video from TV or Webcams, and use 3d acceleration.
Reboot.

Ok dug out an old webcam my wife use to use.
It shows up in skype-static but not in kopete.
Not sure why it doesn't work at all for you, but this was Linux Mint 6 XFCE CE Final live cd.

I just installed Linux MInt 6 KDE CE dev build and it doesn't show my webcam in kopete.
Might just be a problem with kopete.
Enable the community repo in synaptic and update the xfce packages.
That will get you as close to the final as you can get with from the RC1.

Here try this.
http://pastebin.com/m40ed0f51
in order to have a more easy life, ive created a file in /usr/local/bin called skype that superseeds the binary in /usr/bin/ which is in charge of running skype...

type
sudo gedit /usr/local/bin/skype

and paste the following 2 line

#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype

then make it executable
Code:

$ sudo chmod a+x /usr/local/bin/skype


https://bugs.launchpad.net/ubuntu/+sour ... bug/291723
Actually just add this to the bottom of ~/.profile

Code: Select all

export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

Ok this may sound dumb, but it was my problem in the past. Are you using an external usb hub? It may not want to play nice, or the pc may not have enough power to push the hub and cam. My cam doesnt work with the hub at all but it does on its own. Other self powered items like printers work well with the hub.

As well check the usb port works well with another faster usb item, maybe a usb drive to make sure it is transfering data fast (might be dirt or bad connector in the usb slot). Depending on the age of the computer or if its a pci usb card, it may be only a usb ver 1.1 (as it shows for some of your usb devices), vs the newer ver 2. Some newer webcams dont play well with ver 1.1, especialy when it has sound input.

Can you borrow a usb 2 pci card from a friend for testing?

Many Thanks Merlwiz79 !

I had a weird green noisy screen instead of my webcam preview in skype. But on cheese for exemple , all was displaying good.

I tried last week a lot of fix proposed by many users about UVC drivers ; skype forums ; and etc etc.... I loose afternoons and afternoons...

And today I read this as pure hazard reading various linux mint Xfce thread , and tryied the fix you gave , with a bit of adaptation like this:
type

Code: Select all

sudo mousepad /usr/local/bin/skype
( I replaced gedit with mousepad, for my Felicia xfce )

and paste the following 2 line

Code: Select all

#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype
then make it executable

Code: Select all

sudo chmod a+x /usr/local/bin/skype
after I create a launcher on my desktop to : /usr/local/bin/skype
and all was running like a charm , happiness at home !
Thanks again.
