Career

An interview with Packard (center) and Bdale Garbee at linux.conf.au 2014.

Packard gained a BA in mathematics from Reed College, Oregon in 1986. He worked at Tektronix, Inc. in Wilsonville, Oregon designing X terminals and Unix workstations from 1983 until 1988.

He then moved to Cambridge, M*achusetts to work at the M*achusetts Ins*ute of Technology X Consortium from 1988 to 1992, developing the X Window System reference implementation and standards as the senior member of a small team. He was responsible for X releases at this time.

In 1992 he returned to Portland, Oregon to work for Network Computing Devices on X terminals and computer graphics.

From 1999 he worked for SuSE from his home in Portland, Oregon on the XFree86 implementation of X.

He worked at the Cambridge Research Labs of Compaq (and then Hewlett-Packard) from 2001 until 2005 when the lab closed down.

In 2003 he was ejected from XFree86. This led to the formation of the successful X.Org Server fork. He is now project lead on the X.org project, the official reference implementation of the X Window System.

Packard became a Debian Developer in 2004, maintaining font-config (as well as being the upstream maintainer) and other packages.

Packard began working for Intel in August 2006.

Packard joined Debian's Technical committee in November 2013.

Packard started working at Hewlett-Packard's HP Labs in January 2015.

Packard started consulting for Valve in March 2017.

Packard left HP Labs to join SiFive in July 2019, working on free software for RISC-V-based processors, among other tasks.
