comment How to enable the Radeon dynamic power management feature?
"If you are running this release together with a supported graphics card, you don't need to do anything to use this feature." – Except the default setting is 'balanced', so you may want to switch to 'battery' if you want to minimize power consumption.

comment Second hard drive — detection, formatting and mounting
The disk utility is fine for looking up details on disks, but I wouldn't recommend it for modifying anything. It seems very flaky – I've had it crash out from under me – and the launchpad stats seem to support it being currently more buggy than gparted (103 open bugs, one of which is wishlist vs. 21, seven of which are wishlist).

comment How to install zram on Ubuntu 13.04?
Also works in 13.10. To configure the size of the swap (which defaults to half the memory) you can edit /etc/init/zram-config.conf.
