Fixing fugly fonts on Ubuntu version of Packet Tracer
Cisco decided that they would supply their own QT libraries for Packet Tracer. This makes sense when it’s a cross-platform product, but results in horribly ugly fonts, menus and buttons in Ubuntu. To solve this install the following libraries:
sudo aptitude install libqtwebkit2.2-cil libqt4-script libqt4-qt3support libqt4-sql
and then comment out the “EXPORT” line in /usr/local/PacketTracer5/packettracer
You should now have beautiful fonts. Enjoy!

Thanks for this – I had been muddling along in the face of adversity which wasn’t really the best use of my study time. All fixed now though – cheers again!
