How to replace ugly lock screen in CrunchBang Waldorf

xscreensaver.sh

# I followed an instruction at [http://crunchbang.org/forums/viewtopic.php?id=23158]

# Remove old one
sudo apt-get remove xscreensaver

# You may need install dependencies to build xscreensaver
apt-get install libgd2-xpm libgd2-xpm-dev libgdk-pixbuf2.0-0 libgdk-pixbuf2.0-dev libglade2-0 libglade2-dev libjpeg8-dev libxpm4 libxpm-dev libxt-dev

# During installation I got a message that the intltool is missing
apt-get install intltool

# Download xscreensaver sources
cd ~/downloads
wget http://www.jwz.org/xscreensaver/xscreensaver-5.35.tar.gz
tar -xvf xscreensaver-5.35.tar.gz

# Download new images from [http://www.mediafire.com/?s3olvdc9a9dhe3r]
# Put new images to the source directory
xscreensaver-5.35/utils/images/ 

# At the directory of xscreensaver
./configure
make
sudo make install

# After the installation I couldn't lock screen with Win-L combination, getting the error:
# "failed to execute child process cb-lock"
# I found this solution (doesn't work anymore - there is no such packages)
# sudo apt-get install cb-exit cb-lock

# Kill screensaver if necessary
# Look how runs the new one
sudo xscreensaver &
