Ubuntu 13.10 and Darktable
[15:15:31] matt []/Trip Unfortunately, the Darktable developers package the latest versions for Ubuntu, which means it's simply easiest to use that distro. Installing 13.10 at home at least avoided the issues 13.04 had at work with filesystems not being mounted during init (like /tmp), but oddly switching from 12.10 to 13.10 30-bit dual-head became unstable and lost acceleration. 13.10 seems to work alright (or at lesat with accelration) when connected do one output to the Haswell card, but connecting two leads to instability and a lots of acceleration. The same computer, swaping the boot drive, works fine with dual-head 30-bit on 12.10 so this appears to be a software regression as opposed to a lack of general support for the configuation.

Otherwise, upgrading to Darktable 1.4 from 1.2.x has been positive. (Back on 12.10), it feels much faster, especially when turning-on level and curve controls (it seems to have already calculated the luminosity distribution which used to take an annoyingly long time to appear), and more controls can be instanced—this is particularly useful for levels to be used like an ND grad (better than the default ND grad control) and spot removal which can now blend to just affect spots when cloning dust.
