Oh I see, it looks like mining for scotcoins might be more involved than I'd expected. I'd hoped it would be the sort of thing I could've done using spare processing power when my laptop isn't busy! Thanks for enlightening me!

Furthermore the cgminer versions mentioned on your getting started page are outdated, there is only 4.x available. And these versions do not support GPU mining at all (Con Kolivas writes):

Your system reports: Intel's new Iris Pro graphics.

As far as ubuntu 13.10 was concerned the package cgminer was compiled for nvidia graphics cards and installed the module for ubuntu.

Consider running a system with dedicated GPU w/ PCIe: e. g. nvidia and ATI and possibly compile cgminer by yourself.

I tried bfgminer for ubuntu now, see here: <http://jarco.be/install-bfgminer-ubuntu-mint/>

...but cannot get it to work for litecoin scrypt right now...

NOW up and running bfgminer compiled for ubuntu 14.04 with howto from here:
<https://debianhelp.wordpress.com/2012/01/02/bitcoin-mining-in-ubuntu-with-bfgminer/>

with some minor changes:

* installed "bitcoin-qt" instead of "bitcoin"
* `sudo apt-get install uthash-dev`
* `./autogen.sh && ./configure --enable-scrypt --enable-opencl && make`
* modified ".bfgminer/bfgminer.conf" can be pasted here, if you want
  -> 880kh/s @ ATI Radeon R9 290X
