Very useful solution for Skype

bash -c 'LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /usr/bin/skype

it works with my HP ProBook 4520s!

HP ProBook 4520s install driver for RaLink RT3090 Wireless in KUbuntu

There is a Novell SUSE Linux on my HP4520s but I like free software. In spite of that it was bought with my notebook I decided to use Kubuntu. I installed it successfully. Only one that was not discovered was RaLink RT3090 Wireless adapter. To solve that problem I found a solution.
