thanks. got the ubuntu packages installed. highly recommended.

How do they compare to xeffects or -lcd ?

bionnaki · 2008-01-07 08:06:20

well, with my setup, the -lcd packages were too intense for me and gave me a headache. have not tried the xeffects. im absolutely content with the ubuntu patches.

mintcoffee · 2008-01-07 16:27:39

I was using the -lcd packages previously, and the -ubuntu packages have much better weight. the -ubuntu pacthes are not too bold, and the shape of the glyphs are much nicer IMO.

Interesting! I'm using xeffects now, and if I'd switch to -ubuntu packages, and see an improvement, I think we have a winner... we'll see if I can be arsed to test -ubuntu

I can't say I saw a difference between the *-lcd and *-ubuntu patches. But atleast it allowed me to compile Firefox3 with LCD-filtering.

I didn't notice any improvement in qt applications either.
Only in gtk applications, like firefox i noticed better font appearance.
Is there anything extra i must do to see results; I have enabled sub pixel-hinting in kde control center.

capthookb · 2008-01-11 10:56:53

Never mind, i fixed it. I think it had something to do with fontconfig configuration. I erased my previous settings and i fixed it
Great packages :-)

iggy · 2008-01-11 11:30:50

installed the ubuntu-packages from aur. fonts look good, nice alaising.

BUT: the fonts are a bit blurred!! that's is not what i want!

can someone help me?

here is my /etc/fonts/local.conf:

no, not that i was looking for!

iggy, see bug re blurring. Show a screenshot, otherwise there is not enough information being provided.

iggy · 2008-01-11 20:46:00

here is a shot:

i hope, that someone knows/finds a solution!

brebs · 2008-01-11 21:02:19

Your screenshot looks fine. Perhaps your screen is the problem. Try a different "subpixel order", e.g. BGR rather than the default RGB.

capthookb · 2008-01-21 13:39:17

Do you notice perfomance drop when using sub pixel hinting? I can't stand it. The fonts look great but the system gets slow. For example in konsole the text scrolls like in waves, big stripes of text go upwards in slow motion.

Gustavo · 2008-01-22 13:43:12

*-ubuntu made my day. Fonts look much better.

xsdnyd · 2008-02-08 10:35:48

hi, for everyone who doesn't want to compile these packages by themselves...
i updated my repository and it includes now:
cairo-ubuntu
fontconfig-ubuntu
freetype2-ubuntu
libxft-ubuntu
firefox3-systemcairo

so everything to start with the improved font rendering including the system cairo firefox build.
here are the information for my repo:

abstracity · 2008-02-09 19:26:25

Oh my gosh -- text looks so good now! The Ubuntu originals in the AUR work superbly on my dual-head setup (2 LCD; 1 DVI and 1 VGA) as well as on my MacBook which features a glossy LCD display. Thanks brebs and xsdnyd!

For reference, I have these Ubuntu-patched packages installed: cairo-ubuntu, fontconfig-ubuntu, freetype2-ubuntu, libxft-ubuntu.

My .fonts.conf is rather minimalistic:

@abstracity: if you can pull a screenshot I'd like to see the results.

Installed this. My fonts now look much nicer.

Would one of you gentlemen like to add the above package information to this page in the wiki as an alternate method?

Great packages :-)

Just wondering which settings you erased for this? Are you referring to the part from the wiki:

Reset your font configuration:
As root:
rm /etc/fonts/conf.d/*
pacman -S fontconfig

Set the FreeType autohinter. As root :
ln -s /etc/fonts/conf.avail/10-autohint.conf /etc/fonts/conf.d/10-autohint.conf

Well with the ubuntu fontconfig instead of fontconfig then.

Hi there,

I must be missing something, I installed

cairo-ubuntu
fontconfig-ubuntu
freetype2-ubuntu
libxft-ubuntu

I also added the autohint link

(everything compiled and seemed to work)

But ... im missing sub pixel smoothing and everything looks ugly. Obviously Ive messed up somewhere. My laptop has the old version of the lcd fonts installed and it worked great. but my desktop now is a big mess

How would I go about figuring out what is wrong?

Thanks so much for your time
Sam

zenlord · 2008-04-17 08:29:36

Did you look here: http://wiki.archlinux.org/index.php/Xor … figuration ?

Zl.

sambo99 · 2008-04-17 23:22:51

Thanks Zenlord!

I skipped some steps and forgot to install some nice fonts. It all looks really good now.

Cheers
Sam

Yes, not that slow here but still much slower...
