Installing the Lenovo USB Webcam (type 40Y8519, Webpage at Lenovo Products)

under Linux 2.6.31.1 required the gspca vc032x module to be built from an external developer tree,
under Linux 2.6.32-rc5 is working out of the box.

For quick camera testing I have found svv to be very useful.

If problems arise it is also worth having a look at the GSPCA driver maintainer's website.

Skype uses the old V4L1 interface which requires the v4l1compat library to be preloaded. The command for this would simply be:

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

instead of just

skype

Or, on a Debian/Ubuntu 64-bit machine, Skype should be started thus:

LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype

You can replace the commands of your Skype menu item from 'skype' to one of the lines above.
