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
