Bug Description

gnome-settings-daemon takes 5 seconds to register with the session manager, which is when compiz is started (see http://ubuntuone.com/0xKppDPyZiHP9aDzmzzPoR - and this *isn't* a slow machine). I turned on the profiling support in g-s-d, and modified the profiling function to print the profile markers to stdout, with some timestamps. This is what I see (on a cold start):

The point at which g-s-d registers with the session manage is just after its main loop starts to run, which happens straight after this point:

4.393722 0. 6 MARK: gnome-settings-daemon gnome_settings_manager_start: end initializing plugins.

So, that's 4.39 seconds there, before the session even begins to load anything else. Looking through the data shows 3 fairly long delays:

0. 23633 0. 14 MARK: gnome-settings-daemon gsd_power_manager_start: start
0.568517 0.544884 MARK: gnome-settings-daemon gsd_power_manager_start: end

0.569608 0. 34 MARK: gnome-settings-daemon gsd_color_manager_start: start
1. 83437 0.513829 MARK: gnome-settings-daemon gsd_color_manager_start: end

So, the color and power plugins eat up a total of 1 second between them. There surely should be no reason at all for this. The big culprit however, is:

1. 84080 0. 15 MARK: gnome-settings-daemon gsd_xrandr_manager_start: start
3.201221 2.117141 MARK: gnome-settings-daemon gsd_xrandr_manager_start: end

Ouch! Didn't we fix this once already?

No surprises, but the biggest culprit in both the color and power plugins are gnome_rr_screen_new, accounting for almost all of that 1 second

I tried sharing a single GnomeRRScreen instance between plugins, and it shaves a fair bit of time off (it certainly gets rid of the 1 second from the power/color plugins. This bootchart seems to suggest it saves even more though, although I think that's more likely to be some anomaly, like not having my external screen attached)

Actually, I misread the bootchart - I measured up until pulseaudio starting, rather than compiz. That makes more sense now - my change saved over a second compared to the original bootchart

I think we can probably defer the media-keys plugin intialization too, which is what starts Pulseaudio. I just noticed that's adding another second:

The xrandr plugin tries to apply each configuration (backup, intended, default) in turn, and takes half a second for each one even when they don't exist. This seems to be because each call to gnome_rr_config_apply_from_filename_with_time does a gnome_rr_screen_refresh. We should fix it to check if there is even a configuration file first, and then skip all of that if there isn't

I've fixed that problem now :)

One thing I've noticed, is that gsd is still calling XRRGetScreenResources twice if you have a monitor config (monitors.xml - ie, you have this if you've ever changed your display configuration), because gnome_rr_config_apply_from_filename_with_time() does gnome_rr_screen_refresh() before doing anything else. It seems a bit unnecessary to do this more than once at session start, and it sucks that people who have ever changed a monitor setting are hit by that.

What we need is a ubuntu_rr_config_apply_from_filename_with_time_without_refresh() for gsd to call ;)

/me runs and hides

Chris Coulson (chrisccoulson) wrote :

In fact, isn't this refresh totally bogus anyway? After all, with X being asynchronous anyway, the information could already be out-of-date on the server by the time we've finished the XRRGetScreenResources call. And for applications that call gnome_rr_config_apply_from_filename_with_time from some event source off its main loop, then gnome-desktop already refreshes it's state from the server on each RRScreenChangeNotify notification anyway.

---------------
gnome-settings-daemon (3.1.92-0ubuntu3) oneiric; urgency=low

  * Fix LP: #854101 - various startup time improvements:
  * debian/patches/46_share_rr_screen.patch:
    - Share a single GnomeRRScreen across plugins, rather than having the
      xrandr, color and power plugins each create their own, which results
      in 3 reprobes before running the main loop. Thanks to Rodrigo Moya for
      tidying this up a bit.
  * debian/patches/47_delay_pa_connect_to_idle.patch:
    - Don't connect to pulseaudio until we are running the main loop. Starting
      pulseaudio seems to block for around a second here on my machine
  * debian/patches/48_register_client_before_idle_callbacks.patch:
    - Create the GDBusProxy for gnome-session synchronously, and then schedule
      the RegisterClient call with a higher priority. This ensures that we
      register with the session manager as soon as we start the main loop, and
      before running any other idle callbacks

  * debian/patches/16_use_synchronous_notifications.patch:
    - Make the volume notifications work correctly again
