A new x11-6.9.0-i486-14_slack11.0.tgz patch is available for Slackware 11.0 to fix the inadvertent inclusion of two old fontconfig binaries. Installing the original fontconfig patch followed by the original x11 patch would cause fc-cache and fc-list to be overwritten by old versions, breaking fontconfig.

To fix the issue, reinstall the fontconfig patch. The x11 package has been updated so that installation will not be order-specific for anyone fetching the patches now.

Sorry for the inconvenience.

Here are the details from the Slackware 11.0 ChangeLog:
+--------------------------+
patches/packages/x11-6.9.0-i486-14_slack11.0.tgz:
Removed old versions of fc-cache and fc-list.
Somehow a couple of old fontconfig binaries snuck into this package, and prevent fc-cache from working properly at boot (or any other time).
If you've already installed these upgrades, reinstalling the fontconfig package will fix the issue. If you do that, there's no need to reinstall this new x11 package -- it's been fixed so that there's no longer a problem with the package install order (and because those fc-* binaries didn't belong there). Sorry for any inconvenience... Thanks to Petri Kaukasoina for pointing this out. (* Fix *)

Where to find the new package:
+-----------------------------+

HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating additional FTP and rsync hosting to the Slackware project! :-)

Also see the "Get Slack" section on http://slackware.com for additional mirror sites near you.

Installation instructions:
+------------------------+

If you already have x11-6.9.0-i486-13_slack11.0.tgz, check the version of
fc-cache. It should be 2.4.2:

# fc-cache --version
fontconfig version 2.4.2

# upgradepkg --reinstall fontconfig-2.4.2-i486-1_slack11.0.tgz


If you don't yet have the new x11, fontconfig, and freetype patches, the versions in slackware-11.0/patches/packages may be installed with upgradepkg in no particular order.
