Public bug reported:

Binary package hint: unity

On my Gateway LT31u (Radeon X1250, a.k.a. rs690m), unity crashes on
startup. I installed amd64 Ubuntu Desktop Maverick Alpha 2 and then the
"ubuntu-netbook" package. Everything is dist-upgraded.

When I try to log in, the top-left quarter of the screen gets a white
box which disappears soon after; then the background, top panel and left
panel appear. (The clock and indicator applets are present.) After about
half a second, the panels disappear and the whole thing repeats.

The crash occurs in the "mutter" process. I get different crashes
depending on whether KMS is enabled. (I usually disable KMS because
otherwise compiz's wobbly windows cause a crash and
https://bugs.freedesktop.org/show_bug.cgi?id=27529 causes me grief; but
those are bugs for another day.)

Perhaps related to Bug #596292

I've tried putting "AccelMethod" "XAA" and "AccelDFS" "off" into my
xorg.conf; they don't change anything. I've also tried "DRI" "off", but
that just prevents mutter from running entirely.

Attached: three full backtraces, lspci info.
