I think your problem is rooted in ubuntu rather than xleap. Which version
of ubuntu are you using?

Versions 8.10 through 9.04 never came with the necessary x libraries
installed, so xleap could not be installed
without first installing the proper xlibs from aptitude. My solution
to that was to install every instance of x-libraries available through
apt-get, after which I was able to compile and run xleap. However, I
believe that there is either a conflict amongst some of the libraries I
installed, or the ones xleap is looking for are just a little bit different,
and none of the buttons in the pull-down menu work (I don't remember if I
had this problem in version 8.04 LTS). I've never had this problem with any
other platform I used, including Mac OS X and even Cygwin awhile ago, and I
also cannot remember exactly which package(s) allowed me to compile xleap,
since I more often use the text-based tleap and sleap. Moreover, tracking
down the culprit x11 library responsible for these bugs appeared to be too
daunting a task for the returns, so I never attempted it. (Especially since
I had working versions of xleap on my other machines running different
operating systems). Are these the problems you're having?

As user-friendly as Ubuntu is for regular linux use, the installation CDs
are painfully sparse as far as the software they bundle in the CD. Many
packages that come as default in SUSE or Fedora are omitted in Ubuntu (I
believe so they can keep the size of the image to the CD level rather than
jumping up to DVDs like the other distributions have done).

All the best,
