I've been running with your "yellow" PPA since yesterday, and I'm afraid
I'm still having problems.

I'm pretty sure at this point that there are multiple problems here.
mutter still crashes on me regularly (e.g. bug 656414).

Today, I suspended my netbook (while using only the internal LCD) and
opened it again to a black screen (I don't think the backlight even came
on, though it was hard to tell in the lighting conditions).  I had to
hard power it off to get the system back (even magic sysrq didn't work).

I connected my external display, and when the system came back up, I
logged in via gdm, and got only the purple desktop background on both
screens (no Unity). I tried launching mutter --replace by hand, and
among other mutter output (which unfortunately I didn't capture), I saw
this error:

Mesa 7.9-devel implementation error: Bad renderbuffer format: 21

and these errors in dmesg:

[  105.222343] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
[  105.440058] Skipping EDID probe due to cached edid
[  113.210022] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id

[  123.612765] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
[  123.832726] Skipping EDID probe due to cached edid

Restarting the X server seemed to get it working again in this case.
