I'm running Ubuntu 9.04 (Jaunty) on an Acer Aspire 5600 laptop. So far everything works, apart from the regressions in the xserver-xorg-video-intel driver for my 945GM card. However, I have enabled greedy migration, disabled tiling, applied the EXA optimizations, set up a script to fix MTRR and reverted to the 2.4 version of the driver, all as recommended in various threads and forums; these changes have brought my performance back on par with 8.10 (Intrepid), and improved, in some cases.
However, for some reason I cannot get compiz (or metacity, for that matter) to start on login properly. Once logged in I can open a terminal from the menu (gnome-panel's run application doesn't work) and start both compiz and metacity successfully. I can also add compiz to my session startups and have it work, but doing so confuses gnome-do and emerald.
I've fiddled with all the related settings I could find in gconf to no avail. Compiz's crash dumping hasn't turned anything up, and there's nothing in my X error logs.
I was wondering if anyone had ideas on where to look next. Also, a pointer to somewhere that details when and how the window manager is called would be helpful, because I haven't found anything particularly helpful through Google et al.
Thanks!

EDIT: I figured out the problem and posted the solution.
