We messed around a bunch with different migration heuristic options with
the intel driver. Certainly there were some measurable improvements
when using greedy, however it was found to cause graphics corruption on
some systems (indeed, corruption issues are to be expected by design
with greedy).

xserver-video-ati defaults MigrationHeuristic to always. Smart and greedy would

You received this bug notification because you
Just a note: I think smart i generaly better default done greedy for
r280 card that I have. But even greedy would be better than current
driver default always.

There have been cases where turning greedy on with -ati caused problems
on older rv280 cards, so I'm not sure that's a safe option to flip on by
default for everyone.

Hi paniemin,
Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log
(and maybe Xorg.0.log.old) file from after reproducing this issue. If you've
made any customizations to your /etc/X11/xorg.conf please attach that as well.
Please attach the output of `lspci -vvnn`
Setting this to wishlist for now. We'd found greedy to be useful with
-intel, however we also saw a few regressions when changing that default
so I'm a tough reticent to introduce this for jaunty until there's been
more extensive testing for it.
