    You can retrieve a substantial amount of information from your display by using EDID/DDC data. Perhaps some distributions do magic with that information.

    Here is are some examples of how to do it on Linux, primarily with Ubuntu:

    Damn it, when will they have cleartype fonts.

    The combination of X/fontconfig/freetype already provides better sub-pixel font rendering than Windows' ClearType, and has had it for some time (IMHO, Mac OS X's font rendering is still king of the hill, last time I compared). More details here. RH80 and up make the settings accessible through gnome-font-properties (as does any other distro with a recent version of GNOME, probably).

  3. I hate color shading... by Anonymous Coward · · Score: 0 · on Monitor Basics - LCD vs. CRT

    I think it depends of guy.
    My sight is sharp enough so that I perceive some "shading" on LCD even when ClearType (or Unix Subpixel rendering) is switched off!
    ClearType/subpixel rendering irritates me even more...

  6. Sub-pixel rendering can give you 300dpi+ by blorg · · Score: 1 · on Sony To Launch E Ink-based eBook In April
    My laptop does XGA on a 12" screen; this works out at around 105dpi. Sub-pixel rendering, however, raises this to slightly over 300dpi on the horizontal axis. I'm using XP with Cleartype, but that's certainly not the only option. Text looks very very nice indeed, (and no colour artifacts); the only issue is that it's not reflective (or bendable - but I can live with that ;-).

    E-ink isn't colour, so this wouldn't be an issue for it, but I'd still say 170dpi 'paper-style' reflective would be very nice indeed; probably superior.

    I don't have KDE III running yet, but I noticed in the other posts in this thread that people can even get better anti-aliasing.

    The trick is to do some "subpixel rendering", as explained in the Sub-Pixel Font Positioning on UNIX mini-HOWTO.

    You can get cleartype a.k.a. sub-pixel rendering using XFree86. Using the sub-pixel xfree settings, combined with the gdk-xft hack my fonts look perfect on my laptop.

    Here is a mini-howto on setting up sub-pixel rendering:

    libgdkxft, which does subpixel antialiasing, is apt-gettable in debian woody.
    All you need to do after apt-getting the packages is install a bunch of truetype fonts, then add the line 'export LD_PRELOAD=/usr/lib/libgdkxft.so' to your ~/.xession or some other appropriate location:
    I had some issues getting it all working, but that was mostly user error. (I'd been playing with xfstt shortly before trying gdkxft and they seemed to interfere with each other)
    A good howto on setting it up is here
    It makes mozilla look really pretty =)

  14. Using "ClearType" with XFree86, GNOME, KDE by AirLace · · Score: 5, Informative · on Looking Ahead at GNOME 2
    While they are working on basic AntiAliasing, you should try out ClearType [microsoft.com]. It improves font quality up to 800% on LCD screens. The antialiasing level is also adjustable... One caveat: you need WinXP [microsoft.com] to run it...

    Rubbish. XFree86 has supported what Microsoft calls "ClearType" for over a year.

    The method, called sub-pixel rendering, is designed to work with LCD panels. This is why Microsoft are pushing for its use on laptops and palmtop devices. On standard CRTs, it holds no advantage over standard greyscale anti-aliasing.

    A single pixel of an LCD screen is actually composed of three "sub-pixels": one red, one green, and one blue (R-G-B). Taken together this sub-pixel triplet makes up what we've traditionally thought of as a single pixel. This means that an LCD screen boasting a horizontal resolution of 800 whole pixels is actually composed of 800 red, 800 green, and 800 blue sub-pixels interleaved together (R-G-B-R-G-B-R-G-B ...) to form a linear array of 2400 single-color sub-pixels. That's where I guess you got your 800% from.


    "ClearType" can be enabled in XFree86 versions 4.01 and greater by modifying /etc/X11/XftConfig. Just append the following line:


    match edit rgba = rgb;


    An in-depth look into sub-pixel rendering support in XFree86 is available here.

    I believe there is a FAQ on Slashdot on how to make your story preferences Avantgo friendly.

    At this location there is a mirror of the headlines and articles of /. in a Palm-friendly form.

    I suspect that there's a similar thing out that will download websites and translate them into doc format.

    SiteScooper will convert websites to doc. But what you really want is malsync, which is a Unix version of the AvantGo conduit, or Plucker, a GPL'd Palm HTML viewer with it's own conduit (written in AWK, currently being rewritten in Perl).
