Pushed upstream per request: http://freedesktop.org/bugzilla/show_bug.cgi?id=761 From upstream: ------- Additional Comments From alan.coopersmith 2004-06-17 09:37 ------- xdm has code in for using /dev/random, but it's only used if the Imake configuration for your OS is set to use it. Right now, only NetBSD.cf & sun.cf set HasDevRandom. To activate it in your build, try adding this line to xc/config/cf/host.def : #define HasDevRandom YES To add it for your platform in general, look at the existing bits in NetBSD.cf and sun.cf and the bits in X11.tmpl that translate them to flags used to compile xdm. * Wed Sep 1 2004 Mike A. Harris <mharris> - Enable "#define HasDevRandom YES" in host-$arch.def for bug (#126205) Fixed in rawhide xorg-x11, XFree86 4.3.0 and 4.1.0 in CVS for future erratum. Closing as "RAWHIDE". An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.

Description of problem: xdm opens and walks /dev/mem - From what I hear, this is for random data.
