+# [From click to pixel: A tour of the Linux graphics stack](lca_2009)
+
+The Linux graphics stack can be a bewildering thing. What do all those
+names actually mean (cairo? Mesa? Glucose? UXA? GEM?). How can an
+application designer hope to debug a graphics performance problem?
+This talk provides a simple overview of the 2D and 3D graphics stacks
+for Linux with clear diagrams, and several recipes for debugging
+graphics performance problems at several layers. We conclude with an
+overview of upcoming changes to the graphics stack, (in particular,
+several different attempts to unify the 2D and 3D stacks).
+
+Presented at [linux.conf.au 2009](http://linux.conf.au) in Hobart,
+Tasmania, Australia on 2009-01-21.
+
+# [X Acceleration that Finally Works](lca_2008)
+
+Meaningful hardware acceleration within the X Window System is
+becoming a reality. We present the recent state of the art of 2D
+accelerated rendering with the Intel 965 graphics device showing
+performance gains up to 900 times faster than software rendering.
+
+Co-presented with Eric Anholt at [linux.conf.au
+2008](http://linux.conf.au) in Melbourne, Australia on 2008-01-30.
+
+# [Co-maintaining cairo: cool community, cool code](guadec_2007)
+
+A retrospective on the development of the cairo code and community
+over its 5 year history. Co-presented with Behdad Esfahbod at GUADEC
+2007 in Birmingham, United Kingdom.
