Hello, Since some time back Iceweasel on my system does not display some text inside webpages at all. I tried starting it in safe mode, and that didn't fix it. However, it works in upstream's Firefox 3.0.3. This has worked before in Iceweasel 3.0.x; some recent update broke it. An example of a page that is affected is: http://www.cs.lth.se/Education/natfak/ On this page, there is no text displayed at all (except text that 'really is an image'). On other pages, some text is displayed while other text is not, however. On most pages, all text is displayed. // Alexander
Can you try http://glandium.org/blog/?p=209 ? Mike
I already had xulrunner-1.9 of the same version installed, so I just installed the custom libcairo2 package. Still with it, the same problem manifests itself. (After restarting iceweasel, of course). I also tried using the nv Xorg driver instead of the nvidia driver to see if that would help. It didn't. A few more details about my setup: I'm running Xfce from svn trunk (shouldn't make any difference), and I'm using its composite manager (could perhaps make a difference). I tried turning it off, didn't make any difference, though xcomposite is still enabled, of course. If you think it's worth it I could try disabling it. Also, I'm normally using version 173.14.09-5 of the nvidia driver, but as the test with using nv instead indicates, it's not related to the Xorg video driver. // Alexander
What happens if you change Page Style in the Edit menu to No style ? Mike
Then the text is displayed. // Alexander
Is pango-graphite installed on your system? Mike
that spaces between words between very big (o.O).
In any case, I decided to investigate this and strip down a page to
the smallest one that would still have the problem, and got quite
surprised by the results. I had expected the problem to manifest
itself with a specific font. Instead, the problem showed when some
text had a font-size attribute set, whose unit was pt or cm. px, %, or
literals like x-large didn't cause the problem. Here's the resulting
page that has the problem:
<html>
<head>
<style TYPE="text/css">
body {font-size:10pt;}
</style>
</head>
<body>
Hej hej på dig min vän
</body>
</html>
pt and cm units depend on DPI, right? Could it be that iceweasel
detects the dpi as 0? Even setting font-size to 1000pt doesn't make
any difference.
I tried setting a minimum size for text, but that didn't make any difference.
My DPI is set correctly:
$ xdpyinfo |grep resolution
resolution: 96x96 dots per inch
// Alexander
If you open about:config in iceweasel and search for layout.css.dpi, what is its value? What if you try setting it to 96? Mike
Ah, it was set to 0! Setting it to 96 fixed the problem. Why does iceweasel have its own dpi setting anyway? I may have altered the DPI setting in older versions of iceweasel/firefox, however, and if so, it was to make the font sizes consistent with the rest of the system. It does not seem to be possible to set the DPI through the settings dialog in 3.0.x, though. // Alexander
0 is supposed to detect the proper value from the system. Obviously, it doesn't work very well on your system. It would be interesting to understand why it doesn't work for you... Mike
Hello, I have the same problem with Iceweasel that it did not display the text and forms on some pages. Thanks to this bug report I found the solution. I've looked into this issue and found that in the source the value is by default -1 which is also the upstream's value. But somehow this value is set to zero, I suppose during upgrade. So the safe way to fix this is to set manually to -1 which works perfectly for me. http://kb.mozillazine.org/Layout.css.dpi Thanks, Igor Stirbu
It has been set to 0 because -1 also has its problems. http://bugs.debian.org/409074 Mike
This severely impedes the usability of the browser. This recently started happenning to me as well; one thing that might possibly connected is that I switched to fglrx; unfortunately, I currently have no easy way to verify if switching back to radeon fixes the issue again. Nevertheless, vanilla firefox-3.0.10 shows the text fine (using the same profile). Digging into this further, simply absolute-sized text is not shown, so trivial testcase is: visible <span style="font-size: 8pt">invisible</span> xdpyinfo reports: resolution: -2147483648x-2147483648 dots per inch So fglrx reports broken dpi information about the display. This looks like a fglrx bug, but upstream firefox still deals with it fine. I guess Debian uses a patch that does something smart based on the dpi information; in that case, it should guard against obviously bogus dpi.
