Could you describe how to adjust the dpi? I would like to try changing it on my current laptop, to get a feel for if my apps will work in future.

I realise I should be able to read the docs, but I have found lots of different suggestions on how to do it, while you have successfully!

There are a few ways to change the "text scaling factor" http://askubuntu.com/questions/60044/how-do-i-change-the-fon... but that doesn't change the real DPI that X uses. If your hardware supports XRANDR, it should automatically configure your device. If it gets a wrong value or you just want to override it: http://wiki.debian.org/XStrikeForce/HowToRandR12#III.3._Chan...

Unity tweak tool -> Fonts -> text scaling factor.

And for chromium I set default zoom to 125% in browser settings.

I'm using the dpi flag in X. Not sure if it would do the right thing on multiple monitors, but it works great on my Pixel:

What kind of display is that?

Are you happy with it? I've had my eye on Zenbooks for a while. I was about to pull the trigger on one, but have decided to either wait for Haswell, or consider getting a (silly) taichi 31 when they come out.

I have one, I love it. Running Linux Mint 15 with Cinnamon. One thing to watch for is that some kernel versions don't work well with the function keys or bumblebee (for optimus support). I'm running 3.9.4 now and it works quite well.

edit Also, I should add that I did spend the extra money to put a Samsung 840 SSD and an extra 8gb stick of ram in here

I'll vouch for the awesomeness of this exact laptop as well. I run linux in a VM inside it, though.

It's small, the resolution/screen is great, and has everything I need. I also upgraded the RAM and put in an SSD.

Yes. The screen is the best ever notebook screen i had.

After upgrading to 10gb RAM and SSD, it's a really good computer for developer.
