This three day X.Org summit will kick off with the "input" day tomorrow that covers various aspects of X.Org input mechanisms. There will be an overview talk by the Multi-Point X mastermind, Peter Hutterer, and a pointer acceleration talk by Simon Thum (X.Org very recently received Predictable Pointer Acceleration). Covering tomorrow afternoon are talks on improving input latency, run-time GPU power management (not exactly to do with input), and live X Input 2 specification drafting.
The second day of XDS 2008 is what Daniel Stone describes as the "GL-related happiness" day. Tungsten Graphics will be providing a new status update on their Gallium 3D architecture (their Q1'08 status update), a talk about Gallium 3D with Intel 915 hardware, and DRI2 version 2 (the revised DRI2 design following the fallout from the TTM dependences with the original design) to take up the morning. In the afternoon there will be a talk on kernel mode-setting for ATI Radeon hardware, an OpenGL 3.0 talk, and another form of an OpenGL talk is also planned.
The third and final day of XDS 2008 is planned to be just a mix of other uncovered topics. During this time will be Red Hat's Plymouth, Intel graphics testing, an Intel Keith Packard talk, and ending out the day we may just see the release of X.Org 7.4 / X Server 1.5, which is long overdue. Well, the Wiki-based schedule says "Lock doors, no-one leaves until 7.5 released", but that's really for X.Org 7.4 unless they intend everyone to live at the Edinburgh Zoo until the middle of 2009 when X.Org 7.5 will perhaps be ready.
