I have googled this, but most of the information seems pretty old and not very clear and/or distribution-specific.
I'm trying to get a Logitech quickcam working with Slack 11 (2.6.17). When I plug it in, it registers and loads up pwc and related modules, but when I try eg. xawtv I just get a blank screen. v4l-conf gives the error: no overlay support.
Does anyone have one of these working and can suggest what to do. I'm happy to post all the messages if it will help.
