Dear experts,

I installed FreeSurfer on Ubuntu with these commands:

sudo apt-get install tcsh
cd /usr/local/
sudo tar -xzvf ~/freesurfer-*.tar.gz
echo "FREESURFER_HOME=/usr/local/freesurfer" >> ~/.bashrc
echo 'source $FREESURFER_HOME/SetUpFreeSurfer.sh' >> ~/.bashrc
sudo gedit /usr/local/freesurfer/.license
sudo ln -s /usr/lib/libtiff.so.{4,3}

Every thing is Ok except freeview. When I load freeview this error is appeared.

freeview.bin: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

Any guidance on this would most appreciated.
Thanks in advance,
