I can confirm this. I have a Philips Webcam which worked perfectly on dapper and now produces only gray images. This can is also using the pwc driver.
Also if I switch to v4l2 in the ekiga options it can't even open the device. v4l2 in ekiga also worked in dapper. I'll attach dmesg outputs for 2.6.15-26-686 and 2.6.17-6-686. ** Changed in: Ubuntu Sourcepackagename: None => linux-source-2.6.17 Status: Unconfirmed => Confirmed -- Regression: Webcams using pwc driver produce all-grey images https://launchpad.net/bugs/56090 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
