Ok, so here it is again with the media-keys initialization deferred to
the main loop. The session loading time is looking much etter, but still
too slow ;)
Here is the profiling log this time (up until the main loop runs):

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
So, I've got gsd startup down from 5s to ~0.8s now. Using unity-2d
here, my entire session is usable ~2.5s, after entering my password

Ok, I've uploaded gnome-desktop and gnome-settings-daemon packages to
the ubuntu-desktop PPA [1] now. I'd appreciate some testers for those,
just to make sure I've not broken anything and to see if other people
get some startup time wins too

the updates work fine for me and reduced the login time from 5 seconds
to 3.5 seconds on my config.

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
Sorry, thinking out aloud now ;)

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being asynchronous anyway, the information could already be out-of-date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

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

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

even more though, although I think that's more likely to be some

Actually, I misread the bootchart - I measured up until pulseaudio

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