I think this began with the update to Ubuntu Jaunty.

This was not affected by the recent fix for Atunnel (which looks fine now).

We'll need all the information in http://intellinuxgraphics.org/how_to_report_bug.html
Comment 2 Ian McIntosh 2009-10-19 13:10:14 UTC
This is on a Thinkpad T61 with integrated intel graphics and Ubuntu 9.04.

xorg.conf currently has the following (added in attempt to fix graphics performance regressions from Ubuntu 8.10, not sure if they're still necessary or relevant):

Section "Device"
	Identifier	"Configured Video Device"
	Option		"EXAOptimizeMigration"		"true"
	Option		"MigrationHeuristic"		"greedy"
EndSection

Part of the question is how exactly do I reproduce the problem so I can work on it?  Or will it be obvious?  There are no packages for luz on debian at this point, so I haven't gone playing with it yet ;)

(oh, and clear NEEDINFO when answering)
Comment 6 Eric Anholt 2010-01-06 10:43:25 UTC
(got the information to reproduce, now just need to isolate a testcase)
Comment 7 Ian McIntosh 2010-01-13 21:46:31 UTC
would a minimal Luz set work as a test case?

Now that apitrace exists, making minimal testcases is a lot easier -- if you can get the bug to show up in a trace, it makes things much more tractable.  We're not doing much on 965gm these days, though.
Comment 9 Matt Turner 2014-08-11 03:26:03 UTC
Please create an apitrace that can reproduce the issue.

Ian McIntosh, Ubuntu 9.04 reached EOL on October 23, 2010. For more on this, please see https://wiki.ubuntu.com/Releases .

If this is reproducible in a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.
