#Installing libXm.so.3:
sudo apt-get install libmotif3

#Set the env variables:
INSTALL_DIR=/opt
. $INSTALL_DIR/Xilinx/14.4/ISE_DS/settings32.sh
DISPLAY=:0

#starting the main app:
$INSTALL_DIR/Xilinx/14.4/ISE_DS/ISE/bin/lin/ise

When first starting ise, it will ask for a license. On Ubuntu, the LD_LIBRARY_PATH variable is set to Xilinx-compiles stdc++ library, that doesn't allow chromium-browser to start. I fixed this with:

cd /usr/lib/chromium-browser
mv chromium-browser chromium_browser_
cat > crhomium-browser <<EOF
#!/bin/bash
LD_LIBRARY_PATH=
set > /tmp/set
/usr/lib/chromium-browser/chromium-browser_ "$@"
EOF
chmod a+x chromium-browser.

This will of cause stop working after the next update of chromium-browser.
