I've spent the last couple of weeks trying to build a reasonable HiDPI desktop environment on a variety of open source platforms and nothing has the level of fit and finish I am looking for. So far I have been happiest with Elementary OS and their treatments to Gnome... but it preturbs me that getting a new rig setup is so fickle and unrepeatable. You can spend hours tweaking shit and experimenting with no reasonable way to save your changes to be applied later to a clean install or even a different platform. I wish I could check my entire configuration into git.
Would love if the hackers here would share their FreeBSD (or any Nix) desktop environment configuration (including window manager etc...)
