I'm getting a really slow response with the video, the video is sluggish and everything looks quite slow, like as the video lags, what could i do?

You may have set "ximagesink" (X Window System (No Xv)) as video-output. This means, that your cpu is doing all the work. Change it to "xvimagesink" (X Window System (X11/XShm/Xv)) in order to let your graphics card do the work.

Where can I set those things mentioned in the answer above?

Just execute gstreamer-properties (or in the menu: Multimedia Systems Selector) and change it there

My webcam works with gstreamer, but does not with cheese... What's wrong?

Try to change from xvimagesink to ximagesink or vice-versa, maybe that does the wonder.

My webcam works with ekiga, camorama, but not with cheese... What's wrong?

Try to see if it works with gstreamer-properties. If it works there, please file a bug. Else, bug the gstreamer guys ;) When filing a bug, please inlcude the output of v4l-info. If the camera still has a v4l version1 driver you can try running cheeese as:

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

If it is a v4l2 one it is worth trying

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so cheese.

Do you know another Chuck Norris joke?

Of course! Chuck Norris has the greatest Poker-Face of all time. He won the 1983 World Series of Poker, despite holding only a Joker, a Get out of Jail Free Monopoloy card, a 2 of clubs, 7 of spades and a green #4 card from the game UNO.

Where does cheese store my photos?

Depending on your settings, they are stored in the XDG-directories for photos and videos (probably ~/Photo/Webcam and ~/Video/Webcam)

My Quickcam Express (qc-usb driver) doesn't work with Cheese (or gstreamer), and I see errors like "Not enough buffers. We got 1, we want at least 2" in the Cheese output.

Try running qcset /dev/video0 compat=dblbuf to enable double buffer compatibility mode, then restarting Cheese.

Why are my Effect selection buttons displayed as blank grey rectangles?

This is a long-standing Xorg bug which affects the "ati" and "radeon" drivers. A reported solution is to include the following in the Device section of /etc/X11/xorg.conf:

Option "XaaNoOffscreenPixmaps" "true"
