Subpixel hinting, how do I enable it on Sabayon?

Postby LeoFreak » Thu Jan 14, 2010 16:11

Hi, I'm new to Sabayon but no to Linux, using Ubuntu since 6.06.

And the one bigger difference between them is the font rendering. I could not find anything on Google on how to enable subpixel hinting, is there any, painless, easy way to do it? The hard way will be fine, too, but it's not a priority.

I don't know what sub pixeling is but just a simple search of google using "subpixel sabayon" and "subpixel gentoo" turn up some hits. do a search, it cant hurt and the reason I say use gentoo is because we are based off of gentoo and most of their docs can be used for sabayon. hope this helps

Have a look at this topic on Gentoo's forum:

http://forums.gentoo.org/viewtopic-t-805623.html

Among other things, it talks about enabling subpixel hinting.

If you use gnome, I think you can enable it in system > prefs > appearance.
But I have it on, and I still find something strange about the fonts. Way too sharp, and have yellow borders (white on dark bg). Not sure why this is. More noticeable on bigger monitors.

a follow up. I don't think gnome controls the font smoothing at all.
See for example engadget.com. The title fonts are pixelated as hell, no matter what setting I chose in appearance. So maybe the tutorial would help... but what would be the equivalent for
Code: Select all
euse --enable truetype type1 cleartype corefonts

for entropy users? We cannot select USE flags, right?
Somehow, it feels like firefox is ignoring whatever font smoothing settings gnome uses.

On a related note, scroll of sites with many images such as engadget is very jumpy on FF with compiz, passable with metacity. This is using the latest nvidia drivers (190.53. GeForce 8400GS M, 256mb).

No, you cannot affect the USE flags for entropy packages.

However, all the necessary USE flags should already be set.

Give us feedback on any USE flag setting you run across that limits you from enabling a font-related feature, and we'll have a look at it.

You should be able to implement all the items in the link provided using entropy packages.

Following up on this topic, I booted my Sabayon 5.1 K partition, and it looks like many of the font hinting tips I referred to earlier are already impemented.

If you are using 5.1, you may want to look at your ~/.fonts.conf file, and play around with the settings if you aren't satisfied.

I did. The problem is that FF is not obeying the settings that the rest of gnome uses. Maybe it's been built with some USE flags that make it so? I had that problem with tbird 2.0 too (fixed on 3,0): it didn't pick the gnome settings. I use a dark theme, and tbird was still light. Maybe this is the root of the problem (USE flags)?

The yellow borders etc may be a consequence of this lappy using a crappy analog VGA connection instead of the digital one that the ubuntu box uses. I'm sure there's a technical term for 'yellow borders' :). Using the monitor 'auto-adjust' didn't help.

This guide solved my problem partially, the hinting is enabled but it has coloured borders around the fonts.

EDIT: solved in Gentoo way:

Code: Select all
euse --enable truetype type1 cleartype corefonts
emerge --sync
emerge libXft fontconfig cairo freetype


Thank you all for the help.
