next in thread | raw e-mail | index | archive | help
I have just written this new LKM screensaver.
Create the `/usr/src/lkm/syscons/daemon' directory, extract the shar
archive there, compile and enjoy!
(This screensaver may be included in the freebsd distributions, if someone
like it... ;->)
Regards,
