I did some boots with bootchart that show Xorg doing lot work during boot. Xorg log shows that those spikes relate to randr probes.
Might be that the unity-greeter is starting some processes (e.g. gnome- settings-daemon) that call randr and the gtk-greeter doesn't start those? Still, I think those probes shouldn't cause any cpu spikes/lagginess. Default (these are with mainline kernel and some i915 options but default kernel w/o options wasn't any better): - http://dl.dropbox.com/u/14396467/juho-laptop-oneiric-20110915-1.png Disabled extra outputs at xorg.conf (http://pastebin.com/dnGkq8cU): - http://dl.dropbox.com/u/14396467/juho-laptop-oneiric-20110916-7.png Xorg log showing randr probes, lines 453-494: - http://pastebin.com/skKi8nvq -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/828112 Title: Password field feedback slow at times To manage notifications about this bug go to: https://bugs.launchpad.net/unity-greeter/+bug/828112/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
