I found some bugs in Ubuntu 11.04 beta 2. This one is about my integrated webcam not being detected.
My netbook is the new MSI wind U270. This one: http://www.laptopshop.nl/product/127746/msi-wind-12-u270-004nl.html
I found a number of links, like this one:

which mentioned I could find information about my webcam with commands like lsusb, lsmod, dmesg.
If I run gstreamer properties in the terminal, it opens the "Multimedia Systems Selector". I can then test the video input, and get the following message:
[quote]
Video for Linux 2 (v4l2): Cannot identify device '/dev/video0'
[/quote]
And this is the output from the terminal:
[code]
~$ gstreamer-properties

This is the output from lsusb:
[code]

This is the output from lsmod | grep video:

After installing cheese, it either gives me a message that it can't find a camera (no '/dev/video0') or it just doesn't open at all, and I have to force quit it.
I posted this is a forum, and was told to file this as a bug report, I hope this is useful.
I had a similar problem with my new MSI X370. I found that pressing "Fn-F6" (has a round webcam pic on the F6 key) and then running lsusb again gives me this.

You may have tried that already, but I went a week thinking my webcam wouldn't work before I tried that. lsusb before doesn't have the BisonCam line. Hit Fn-F6, and run lsusb again, and poof... there it is. Cheese works great after that (though I don't think it's a stellar webcam).
Hope that helps.
