i.e. I add "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so" to my ~/.profile and

I adapted my ~/.profile accordingly, but when trying to preload the library I
get:

ERROR: ld.so: object '/usr/lib/libv4l/v4l1compat.so' from LD_PRELOAD cannot be
preloaded: ignored.

Workaround: when creating a symlink (ln -s /usr/lib/i386-linux-gnu/libv4l
/usr/lib/libv4l) it works again, so it seems some hardcoded path is still
pointing to the old location?
I checked all library files by calling "strings libxzw |grep usr" and
could not find a hardcoded reference.
Could you please send the output of ps auxewww|grep skype when
preloading fails?
You could also export LD_DEBUG=all (see man ld.so) to get debug output
from the dynamic linker.
Note: If you add LD_PRELOAD to your profile than every started program
will contain libv4l.
¹actually, the "fix" just flips the video image on top, i.e. it is still
mirrored, not properly turned by 180°.
Please send the output of
more /sys/class/dmi/id/*
Thanks,
Gregor
