This is an old card I expected no problems in the latest slackware release. I'll try the option and upgrade XFree86 when I get time. It doesn't look a big download though... > 4.2.1 is a minor revision of the full 4.2.0 release which must be > installed first.

Now that's misleading, as you say, it isn't only a security fix, it has other important bugs fixed also. I should have read the release notes. Reading the "Errata" it says the security bug isn't fixed...! Perhaps best to wait for a new binary release then. I'll RTFM to find out where NoCompositeSync goes - with the modelines? Thanks again, Ant ps. Is this a suitable forum for Cygwin XFree86 problems? _______________________________________________ Newbie@XFree86.Org *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie
