Attempting to install DisplayLink driver for Xenarc 700TSU on Linux Mint 17.2. Here's what I get including a dump of the kernel version:

It looks like the .run file starts but when it tries to invoke displaylink-installer.sh it some how does not have sufficient permissions. I don't know enough about Linux to understand why.

New additional output using bash -x to invoke the .run file
