Or even better, use something like Flux[1] to subdue the tones of that glaring white screen just enough to reduce eye strain.

Oh wow, thanks for this one. Immediately noticed a reduction in eyestrain. If you're found the GUI buggy (as I did), try the command line interface (xflux). The CLI app works fine for me.

I need to try out the linux version of flux, but the mac version is seriously awesome.

Has helped fix me off of getting off the computer at night with the color/gamma changes.

F.lux is indispensable on Mac and PC (when I still had a PC.) Absolutely required if you code at all during evening/nighttime.

Unfortunately I couldn't get it to work* on my Ubuntu box and found another app, Redshift, that seems to jive better with Linux: http://jonls.dk/redshift/

* Ran without errors, but didn't tint my screen. I chalked it up to oddities of video card drivers on Linux.

The solarized color scheme is great too.
