A few weeks ago I suddenly noticed that konsole in kde was giving strange fonts. It seemed to me after I had installed fontconfig. One particular problem is that certain fonts give a double spacing when used in konsole. I reported this as a bug at kde. see http://bugs.kde.org/show_bug.cgi?id=52538 for a complete description of the problem including a screenshot. Removing fontconfig did not seem to make the problem go away, so I re-installed it. Furthermore, I was also able to show that this only seemed to be affected when a) The fonts have a -c- or a -m- in the font descriptions (in the font spacing field), AND b) the metrics showing the character width in pixels etc were NOT zero After a bit of work with a debugger I discovered I could reproduce the situation at will with a simple qt application which toggled the Fixed Pitch Property of a font. With it on, the font displayed in a simple edit box as double width, with it off it displayed normally. I have spent over a week now with this little application and a debugger (gvd) single stepping my way through the qt libraries (built from source) in order to try and figure out what is going wrong. I still havent got far enough into it to figure this out. (its complicated :-( ) As I am going to be staying in a hotel tomorrow night, I transfered this development enviromment to my laptop (which also has debian unstable installed) in order to spent my lonely evening trying to do some more debugger work trying to understand this. HOWEVER - the application did not show this problem as a bug on this machine. A quick check showed that fontconfig was not installed (although libfontconfig1 was). So I installed it. This made the fonts in konsole show the symptoms of the problem, although my little application now worked perfectly (maybe because its using the default fonts). I tried to do a comparison with /etc/fonts/fonts.conf between my two machines to see if anything was different. I had added console font as one to be aliased to monospaced on my main machine, so I tried adding that to the same file on my portable. This didn't make my test program produce the symptoms. So I removed this change again. Anyway, after this process I did a dpkg-reconfigure on fontconfig. After I ran that on my laptop, my application now shows the symptoms of the problem. Now I am not sure how fontconfig works, but whilst it is doing a dpkg-reconfigure it says it is regenerating the font cache. It is almost as though running through this process more than once changes the outcome. Where do I go from here? I now can't make the application go back to working again - so I will probably spend some more time with the debugger trying to see how qt knows where to put the cursor (it seems to take care of the double width properly). Only one other person seems to have seen the same symptoms as me - so I am puzzled as whether this should be reported as a bug, and if so what in (fontconfig? libxft? libfreetype? libqt?). I tried asking questions on the fontconfig and qt-interest mailing lists - but no-one has replied. Any help here at getting to the bottom of this welcome. - -- Alan Chandler [EMAIL PROTECTED] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE+Nv0PuFHxcV2FFoIRAqtMAJ4+yRKthCKBeaoe6qt+WoYsK4hZ7ACfQYsr u5uIMefTOuDWu8YXa7OrBXI= =qbK7 -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
