General ⇒ texlive-latex3 on two different machines

[prudra]

I have two 32-bit machines, a Zenith India Always On Netbook and a Dell Vostro 1014 laptop with gnome-default Desktop. On both I have Debian Wheezy 7.2 installed from Live *.iso on usb media.
And on both I have installed #apt-get install texlive-laex3 .
But when I run $xdvi group.dvi & I get two different things.
On the netbook the xdvi frame shows on the right hand column (as is usual) successively File, Navigate, Zoom, Mark, Modes, Options, Help and then the pages of the paper. This useful feature is missing on the Dell Vostro 1014 laptop. Because of this absence using this laptop has become very inconvenient.


First, why this difference? Secondly, what shall I do so that Dell machine shows like netbook.pdf?
Thanks for help.
