Bug#697854: closed by Holger Levsen <holger at layer-acht.org> (Re: Bug#697854: general: Fail to display video)

[Ralph Ronnquist]

The problem in cheese is that the preview display is black. It does snap 
from the webcam but the preview screen remains black. But, if I run 
cheese with X11 redirection to another server, then the preview display 
on it is not black. That's how it relates to cheese.

I don't know anything about the details, but I would agree that this 
probably comes up due to some kind of library mismatch in X or how 
cheese (and other programs) use X. Tonight I will test Anne Bezemer's 
solution (that I got via direct email), which is to use 
DISPLAY=localhost:0.0 rather than the default, and hopefully get it 
working in that way.

Whichever: this clearly is a bug in Debian 6.0 (on that machine). Last 
week I had Linux Mint 12 on the same machine, and not this problem;
it operated the display without workarounds.

It probably is not local to cheese, but cheese is a good and easy way of 
triggering it. Hopefully this bug can remain open, though filed in the 
right bucket, at least until I have my workaround. And then someone with 
deeper insight might make something useful of it.

regards,

Ralph.
