ECW support worked with previous ubuntu relases, because there was a 
libgdal-ecw package at ubuntugis unstable, complied for GDAL 1.10 up to 
ubuntu raring. There is no package for trusty yet, and because QGIS 2.4 
is built against GDAL 1.11, the old package will not easily work.

I have described a workflow to rebuild the driver here:

http://gis.stackexchange.com/questions/94870/unable-to-install-ecw-support-on-lubuntu-14-04

It works for plain ubuntu as well. I did this with QGIS 2.2, and after 
the update to 2.4 it still works.

Maybe someone more familiar with ubuntu could create an ecw package for 
current GDAL 1.11.

HTH,
