Ubuntu :: Rendering Of Characters In Firefox?

Jan 29, 2011

I have a weird issue in Firefox on Ubuntu 10.10, and sadly it's a periodic mistake that I don't know how to initiate... Sometime in firefox some of the characters seems not fully rendered, and as I recall it can also happen in menu fonts sometimes. In the attached screen-shot you can see that it's the a character that has the problem - but only for one font type or? But I have seen this with most characters I think - and as stated this happens randomly.For instance right now I looked again in the tab in firefox where I just 5 minutes ago did the screen-shot and now all characters are correct?? I have tried to reload or even restart firefox when it occurs, but this is now guaranty for a solution... When it happens it makes many homepages unreadable

Ubuntu :: Inconsistent Font Rendering In Firefox?

Sep 17, 2010

able to find anything on this particular issue. The problem I'm having is that the contrast ratio of text in firefox seems very inconsistent. For example: if I'm reading an article on NYtimes, from one paragraph to the next it looks like some sentences are in bold-face and others are not. If I refresh the page, it'll be different areas that are or aren't bf. Sometimes they even change (getting darker or lighter) as I'm sitting there reading. I tried to take a screenshot but unfortunately the text all becomes uniform as soon as I hit prt-scr so the image doesn't show the effect.

Another example is viewing my personal favorite forum where threads that I haven't read are in bf as opposed to those I have read which are normal. The problem is that when I do a mouse-over of the bf threads the font rendering becomes more greyed out. It's still bold-face, just not as dark.

A final example is in text-entry boxes. As I'm typing this right now the line I'm on looks normal but the paragraph above seems to go from regular to bold-face from one line to the next. The paragraph above that looks entirely bold-face...

It did occur to me that this could be a monitor issue or even a vid-card issue. But it's definitely not monitor because I can scroll the whole screen and the variation moves with the text... And it's not vid-card because I installed Chrome as a check and it doesn't have the same problem. None of the above symptoms carry over to that application.

Fedora :: Font Rendering Bad Only In Firefox

Jun 10, 2010

I'm running Fedora 13 x86_64 on a Dell Precision Workstation with a Dell Flatscreen Monitor. My fonts render well everywhere, using Dejavu fonts, but in Firefox and Epiphany they have these terrible yellow outlines and jagged edges.Has anyone else seen this? I've only noticed it recently (since the upgrade to Fedora 13), but it also happens on a Fedora 12 machine at home.

Ubuntu :: Tried Firefox 3.6 From Daily Repo - Totally Ruined Font Rendering On Entire Sys

Jan 23, 2010

I used the directions from this thread: [url]

Then after installing it, I realized not only did firefoxes fonts look terrible, the fonts on the entire system were totally different, they look terrible.

So I uninstalled all the new programs, removed the new moz repository, and then reinstalled the regular firefox 3.5 from regular ubuntu repos. Dropped all support software down to 3.5 as well. System fonts are still totally fubar!

I tried creating a .fontconfig file with the text from the threads, supposedly to fix the new firefoxes fonts, and it did not help.

As my fonts looked absolutely wonderful, now they look terrible. I tried messing with all the settings in the appearance tab of the gnome menu, nothing seems to help!

Regular firefox is back, and running fine, but its fonts and all the rest of the fonts on the system look horrible, like they are not getting aliased/hinted at all!

Ubuntu Multimedia :: QuickTime Renderer Was The Only Rendering Container That Didn't Result In Sped-up/compressed Video Or Correct Rendering For Just Fifteen Seconds?

Total: 30 MBI experimented with about seven rendering containers, and QuickTime renderer was the only rendering container that didn't result in sped-up/compressed video or correct rendering for just fifteen seconds.How in the name of all that is holy did this rendering end up with 570 extra MB?

Ubuntu Multimedia :: "Nvidia: Direct Rendering Failed, Attempting Indirect Rendering"

Apr 3, 2010

I recently downloaded Frets On Fire and the HRP Polymer pack for Duke3D...Duke3D runs fine with just EDuke32 and no mods, just Duke3D and EDuke32. But when I try the HRP Polymer pack, it says in Terminal "NVIDIA: Direct Rendering failed, attempting indirect rendering." This is fine...if I want the game to lag like hell, I'm sure my video card and the driver for it support DR, the video card is a NVIDIA Geforce FX 5200, the same message appears in terminal when I run Frets On Fire, I think it does with other games too, if someone could explain how to enable Direct Rendering.

Ubuntu :: Firefox Incorrectly Displaying Some Characters?

Jun 23, 2010

I've been seeing things like this in Firefox since installing:


where the is a special/accented character. I've also been seeing the in places that seem likely to have some kind of quote mark, probably curved quotes. I can see straight single and double quotes. To correct this, I've tried changing the display font and the character encoding. I've also looked at the Mozilla Add-On site to see if I could find a plug-in to fix it, to no avail.

What should I try now? Currently I'm using Liberation Sans with UTF-8. I'm a native English speaker so I need a western encoding (I think), but I'd still like other characters to display properly.

Ubuntu :: Partial Characters Displayed In Firefox?

Oct 15, 2010

Firefox is having trouble displaying characters. At times, a web page will display only partial of a certain character, and it will affect every character on the screen. In other words, sometimes when I load a page, the bottom half of all the 'i's or 'r's are missing. The problem persists when I refresh the page, and resolves on its own. It will happen to most web pages. Also, at times, a white or black stripe will run through some characters, usually a heading title on the page. I'm running Firefox 3.6.10 on Ubuntu 10.10. I did a complete reinstall of Ubuntu 10.10 when it came out (i.e. I reformatted and installed 10.10) and have been having this problem since then. Never had the problem with 10.04, which I had been running since May. Firefox and Ubuntu are both updated currently.

Please note the attachments, where in one there is a problem with the letter 'i', and in the other, on the Heading "Search New Posts" there are white lines running through the words.

Ubuntu :: Delete All ASCII Characters In File - Leave Chinese Characters Only

Jul 8, 2011

What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.

I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?

General :: Does Non-printing Characters Escape Characters Still Needed For PS1 Definition?

Aug 28, 2011

While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?

Ubuntu :: Pdftotext Rendering Between OS?

Feb 10, 2011

I had a working pdftotext script working and custom made a parser for the info in it, but upon moving from CentOS 5.5 to Ubuntu (version unknown) and installing poppler-utils, pdftotext works, but the rendering is different by quite a bit causing a ton of issues. I also tried on another CentOS (5.2 this time) and it rendered the same as Ubuntu. I'm trying to figure out the problem so it renders the same, I'm using the same code and everything.

Ubuntu Multimedia :: CPU Doing All Video Rendering?

Oct 21, 2010

I am completely new to Ubuntu and so far am pretty happy. I am running into an issue playing web videos, ..... (flash) as well as html5. What is happening is that the CPU is doing all the work instead of the GPU causing the video to skip/stutter, here are the system specs.

MSI K7N2 Delta 2 LSR (latest bios)
AMD Athlon XP 3000+ (Barton)
2GB's PC3200
nVidia 6800GT (AGP)
Ubuntu 10.10 32bit (fresh Install
nVidia driver 260.19.06

When video is played the CPU's useage climbs to 100% and video lags. Again I am completely new to Ubuntu as well as Linux but I am trying, lol.

Ubuntu :: (10.10) Differences In Font Rendering Between Qt And Gtk?

Mar 7, 2011

I've got a slight problem here, and have had it for a while: When I use the "Sharp'N'Clear" .fonts.conf from Here, and set an optimized font like Arial, gtk-based applications render correctly, while Qt-based ones don't As you can see, the top window(Firefox) has it's fonts clean and nice. The bottom one(Dolphin) does not. Both are set to Arial 9. I've tried it with a number of different applications, including some custom PyQt4 stuff, and it's clear that it's -all- Qt-based applications and not just one or two.

For further information, I've had this problem ever since I upgraded from Kubuntu 9.10 a while back - That version worked correctly on both Qt and gtk, but nothing since has.

Ubuntu :: Fonts Not Rendering Properly In KDE Applications

Jan 25, 2010

I've seen a few people are having this issue, so i wanted to start a main thread. My problem started... After installing qt4-designer onto my Ubuntu 9.10 Gnome OS, the fonts in certain applications looked distorted like enlarged bitmaps. I tried uninstalling designer, reinstalling components, using qt4-config to restore fonts, but nothing has fixed this issue.

The issue seems to be specific to KDE applications such as: qt4-config, Amarok v2.2.0, skype, akonaditray, ktorrent, etc. Also, in qt4-config it seems to be specific to fonts between the sizes 9 to 12 inclusive for all font faces. All other font sizes seem to be okay. I've attached some examples.

When i first tried to install qt4-designer, it indicated the following dependancies: fontconfig-config libfontconfig1 libfontconfig1-dev When i try to remove fontconfig-config, it indicates that it is dependent on nearly every application in my system (including drivers and xscreen). Hence, I would need to uninstall everything and reinstall everything!?

Ubuntu :: Unity Will Not Start / Direct Rendering?

Dec 24, 2010

Version: 11.04 (At least that's what the About Linux file tells me)
Graphics Card: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)
System: Dell Netbook. Nothing remotely fancy.

After a night of trying to adjust the graphics settings to work with a reasonable game, I powered down for a few days and went hiking in the woods. Never got the game to work, but I had no problem restarting X and continuing to work. Thus, I assumed nothing was wrong. The only real change was the installation of DRIConf. Upon my return, I started up only to see my desktop background image load, and no GUI. No cursor, no Unity, nothing. When I boot up in recovery mode, GNOME seems to work perfectly fine. If I open DRIConf, though, it says that no devices can be found that are capable of direct rendering. My glxinfo output is below (clearly indicating that direct rendering is working). I assume there's a relationship between these problems. I just switched to Ubuntu a few months ago and am obviously a bit beyond my depth.

name of display: :1.0
display: :1 screen: 0
direct rendering: Yes
server glx vendor string: SGI

OpenSUSE :: Kdenlive Not Rendering DVD

Mar 29, 2011

Having upgraded to from 11.3 to 11.4 I now am unable to render in KDENLIVE. I've installed MLT, FFMPEG and KDELIVE with dependencies from Packman.

What is different from my 11.3 install is MLT has moved up a notch. 0.5.10 to 0.6.2. Does 0.6.2 work with KDENLIVE 0.7.8? I would think it should.

I have see MLT 0.7.0 is released but will wait for the RPM to be released on Packman.

This is the message taken from terminal.

Ubuntu :: Screen And Vim (256 Colors) Background Color Rendering?

Feb 18, 2010

I'm using xterm/screen/vim, and set them up to 256 color mode. Everything went well, except when background color for the theme I choose is not black.

Here's the theme I use in this example:[URL].. Here's the situation: as long as I only use vim, the background is well rendered, meaning everything is grey in vim background. But when I try this with screen, the background is back to black, and only the text get some kind of highlight with the background color.Here are the magical lines I added to screenrc:

term screen-256color
attrcolor b ".I"
# Tell screen how to set colors. AB = background, AF=foreground
termcapinfo xterm 'Co#256:AB=E[48;5;%dm:AF=E[38;5;%dm'
# Erase background with current bg color. Not needed if TERM=screen-256color
defbce "on"

Colors are well rendered in 256 color, I only have a problem with this background. Anyone knows how to 'fix' this?

Ubuntu :: Ugly Font Rendering Inside Some Webpages ?

Apr 2, 2010

This happens to me with any browser (tested: Firefox, Chrome and Opera) and DE (tested; Gnome, KDE, LXDE). While for the most part, the text is OK, some text looks quite messed up (please look at the attachment for an example).

By inspecting the affected pages, I fond that usually (maybe ever?) when the characters are garbled, the font is Tahoma.

Then I tested with The Gimp and its text tool: I choosed Tahoma and I tried to type something inside an image. Same issue. It seems to happens when the font size is 14 px or >= 17 px.

Ubuntu :: Sharp Windows-like Font Rendering Not Working?

(LINK) This is how bad the fonts look in google chrome

(LINK)This is my .fonts.conf, I have anti-alising disabled for all fonts there (I think), so the fonts would be sharp

Ubuntu Multimedia :: 10.04 Fglrx Bad Rendering In Gdm And Without Desktop Effects?

Dec 23, 2010

My new machine with a fresh install of Lucid boots up and displays the standard gdm login screen showing the list of users which looks fine. After you hover over a name or other option menus on the display, the pop-up or screen change is rendered poorly. It very slowly fixes itself over time. After I login everything works just fine even with the extra "desktop effects" I recently discovered that if I set the desktop effects to none, I get the same effect on my desktop. I've attached a screen capture to illustrate what I see but find hard to describe. The little horizontal bars will gradually be fixed over a minute or so. Dragging the window around smears that effect around the screen. I've been sniffing around the web off and on for a couple months now but haven't found anything that sounds similar.

Now for some hopefully helpful configuration data: This system is based on an Asus M4A89GTD PRO/USB3 motherboard with integrated ATI radeon video, and a 6 core processor. Lucid 32bit.
