Both dwm and xfce have worked just fine on my chromebook pixel. This is on debian 7. The only two applications that have given me issues are ones that do their own custom rendering - Chromium and Sublime text. Both of them have some UI text that cannot be resized and does not appear to respect system dpi settings.

It seems ironic that Chromium should give you issues on a Chromebook. Does (non-free) Chrome work?

On ChromeOS chrome works just fine. On debian webpages are rendered perfectly because I can change font settings for those, but the tab titles are drawn with text that is too small. There is no setting exposed currently from what I can tell to control the font of the tab titles.

Have you tried Sublime Text 3 beta? I know that it is suppose to support support Retina under Mac OS X.

He's talking about linux machine. Sublime Text 2 seems to support retina displays just fine with mac os.
