Comment 6 for bug 794666

If the above error occurs but on either a 32 or a 64bit system, in order for the window to show up correctly you only need to paste these commands to the terminal:

#create symlinks
sudo ln -s /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-gnu/libX11.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libX11.so.6 /usr/lib/x86_64-linux-gnu/libX11.so

#create program folder and program settings file
mkdir $HOME/.complexshutdown/
touch $HOME/.complexshutdown/settings.cfg

Have a nice evening
