12757 2002-12-26 20:21 0000 gdmgreeter always crashes on gdm-2.4.0.12-r2 2005-03-01 22:23:33 0000 1 1 1 Unclassified Gentoo Linux Ebuilds 1.4_rc1 All All RESOLVED FIXED P2 normal --- 1 tester@gentoo.org gnome@gentoo.org dberkholz@gentoo.org tester@gentoo.org 2002-12-26 20:21:16 0000 I upgraded to gdm-2.4.0.12-r2 from gnome-base/gdm-2.4.0.11-r1... I dont really see what causes the problem.. I tried replacing all of the "customised" config files with the defaults ones... didnt change anything... jackmaninov@loadedweb.com 2002-12-31 15:23:15 0000 I noticed the same when I upgraded to 2.4.0.12, and tracked the issue to having sub-pixel rendering turned on in fonts.conf. tester@gentoo.org 2002-12-31 17:04:31 0000 It also works here when I disable sub-pixel AA. Btw, I use Gtk/glib 2.2.0, pango 1.2.0 with fontconfig 2.1-r1 and xft-2.0.1-r1.. Btw is it possible to disable sub-pixel AA for a single app? jackmaninov@loadedweb.com 2003-01-02 14:27:20 0000 I use the exact same library versions as you (with freetype 2.1.3-r2 in addition). I also find that Nautilus (2.0.8) crashes when I attempt to open a window with sub-pixel rendering on (it renders the desktop fine). I was having the exact same problem with GDM before the latests gtk/glib/pango were released. tester@gentoo.org 2003-01-02 15:43:40 0000 I also have the same problem with nautilus... I filed this bug on bugzilla.gnome.org.. They called it "not gnome". http://bugzilla.gnome.org/show_bug.cgi?id=102322 jackmaninov@loadedweb.com 2003-01-02 16:12:21 0000 Downgrading to fontconfig 2.0-r4 has fixed this for me, and zooming in on a screenshot confirms that sub-pixel rendering is indeed working. This appears to be a bug in fontconfig-2.1 and up. tester@gentoo.org 2003-01-03 09:02:57 0000 I get the same results with fontconfig 2.0-r3 -r4 and 2.1 -r0 -r1.... (None of them works correctly) foser@gentoo.org 2003-01-09 11:54:56 0000 Disable subpixel in /etc/fonts/fonts.conf , try the gnome2 fonts dialog to set subpixeling with that. foser@gentoo.org 2003-01-11 11:19:17 0000 Any word ? jackmaninov@loadedweb.com 2003-01-11 20:17:26 0000 I set subpixel rendering in the gnome2 font dialog, but when I take a screenshot and blow it up you can tell that it hasn't actually been enabled; only standard antialiasing is being used. foser@gentoo.org 2003-03-03 19:12:34 0000 1) seems the fonts.conf way of enabling subpixel rendering is faulty -> there is no name 'rgba' ? i'm not quite sure how this all ties together. 2) My suggestion of enabling subpixel rendering in fonts dialog won't work for gdm i think since it runs as its own user, but for users it should run fine. I can with correct settings see subpixelrendering done in colors. Can anyone confirm 2) and figure out what the correct way for setting it in fonts.conf is 1) ? liquidx@gentoo.org 2003-03-03 21:38:47 0000 ok, the crash disappears with gdmgreeter if i comment out the <test> block in the "subpixel" match block. something like this: <!-- Enable sub-pixel rendering --> <match target="font"> <!-- <test qual="all" name="rgba"> <const>unknown</const> </test> --> <edit name="rgba" mode="assign"><const>rgb</const></edit> </match> it crashes if the <test> part is uncommented. i'm not sure if i understand this XML at all, to be honest, but it seems to be part of the default configuration. redhat 7.3 doesn't have that test in its fontconfig default conf files. foser, i can confirm 2. the settings in font properties set the user's own font rendering settings, and not the global ones. foser@gentoo.org 2003-03-04 06:07:35 0000 with the test disabled (which doesnt seem to be correct allright), there is no subpixel rendering in gdm at all afaics. Altough in one of the fontconfig sample configs it is mentioned like that (without the test block). liquidx@gentoo.org 2003-04-17 20:06:20 0000 I got a core dump off gdmgreeter and the segfaults happens deep inside fontconfig code. And as luck would have it, a new fontconfig has been committed to portage and fixes this problem. So, does the new fontconfig solve the gdmgreeter crashing for you? To me, the fonts look like they're using sub-pixel rendering. Remember you have to edit /etc/fonts/local.conf and uncomment the subpixel xml stanza. foser@gentoo.org 2003-05-14 19:32:09 0000 just added 2.2.0-r2 which should include a local.conf without the test stuff. please test so i can mark it stable and mark stable foser@gentoo.org 2003-05-14 19:41:15 0000 fontconfig that is ;) liquidx@gentoo.org 2003-05-15 05:52:56 0000 foser, seems to be a problem with the cvs_bugfixes patch applying : ... -------------------------- |Only in fontconfig: .cvsignore |Only in fontconfig: CVS |diff -ur fontconfig-2.2.0/ChangeLog fontconfig/ChangeLog |--- fontconfig-2.2.0/ChangeLog 2003-04-17 19:43:04.000000000 +0200 |+++ fontconfig/ChangeLog 2003-05-14 18:29:07.000000000 +0200 -------------------------- No file to patch.
