    Hinting / Antialiasing / fonts broken?

    I'm using professional IPS monitors properly adjusted to reduce eye strain. It's not a problem with the monitors (unless it affected two monitors simultaneously). Something seems to have happened to hinting / antialiasing / fonts / something with latest updates. Text is now grainier than my Kindle DX.

    This is particularly noticeable in PDFs using Adobe Reader or Document Viewer. Google Chrome and Chromium seem to render fonts a little better but still not normally. Firefox / Thunderbird fonts look just awful. Dash text is also looking not properly rendered.

    Hinting is set to "Slight" and "Antialiasing" is set to "rgba". I have tried Hinting = None/Slight/Medium/Full vs AA = None / rgba / Grayscale 12 combinations and all are worse than Slight+rgba anyway.

    Considering we had some font problems recently, I was wondering if anyone knew of a workaround. I already have enough daily headaches with normal fonts.

    Regards,
    Effenberg

    I don't have the classy monitors you have - just two different Sony Vaio laptops running Quantal, with whatever LCD panels Sony uses. One has Intel graphics, the other nvidia with the ppa 304.43 proprietary driver, both fully updated this morning. I've only checked firefox and the dash so far, but font rendering seems to be as good as it has been.

    I'll keep a watch out in case it was an update that has caused your issue, and in case the update hasn't got to the update server I use.

    Please do not PM me about your forum account unless you have been asked to. The correct place to contact an admin about your account is here.

    I had this problem, a week or two ago. Matter of fact, a lot of ppl were complaining about it, during the nVidia escapades.

    At that time, I couldn't even log into Unity/GS, but the poor rendering quality was driving my eyes buggy in LXDE/Openbox.

    The "cure" in LXDE was to install a compositor. I chose XCompMgr, and the difference was jaw-dropping.

    Haven't had a prob in Unity, so fiddling around with the compositing/compositor effects hasn't been required.

    There are 4 panel manufacturers (3 groups, actually) that manufacture 90% of the world's panels. Each has 2 to 4 tiers of panels (for low-end, standard, high-end monitors/laptops). Sony gets first tier high quality TN panels. I got this two Dell U2412M from a client as part of a payment for small IT services. Actually, I get a large part of my hardware that way Anyway, I recently invested in getting this professional monitors, installing adequate lighting in my home office (replaced incandescent bulbs for LED), new eyeglasses with lens specially designed for computer, etc because I was having terrible headaches 3 to 4 days a week. But I still am having them, I think my brain hates me (too).

    Yea, it's making me mad :\ I have low degrees of astigmatism and myopia, it doesn't require thick glasses, etc. Normally If I force my eyes I can use the PC with no glasses at all. The way it is right now I'm unable to distinguish between dot vs comma and colon vs semi-colon. It makes my eyes useless for C++.

    I tried to improve the situation using unsettings (or was it was gnome-tweak-tool, I can't remember) to change font faces/sizes. It made things worse and now I don't even remember what were Ubuntu defaults.

    You're probably right Vin, I was holding Unity updates before this problem. I have just updated, rebooted, purged/reinstalled X and Unity packages with no luck. I'll try to find the source for this later today. I never fiddled with fonts and rendering stuff, so I'm not sure what would be the packages, config files to play with.

    I have this problem too, mostly in firefox. It happend when I did this: sudo apt-get --purge remove libreoffice*. When that command finished what it had to do, fonts in firefox got ugly in the instant.
