I use 12.04 on an intel IVB laptop at work and have been patiently
waiting for a fix for 12.04 to be released for 6 months now. My laptop

open xterm and start typing what you type will be garbles, but the

Fedora is now including the work around patch in their stock kernels
(called drm-nouveau-evo-hang.patch). I've been running this patch on
top of the stock ubuntu kernels for months now with no negative side
effect. The impact of the patch is low, as its
Stack Trace added, should be enough to debug or at least file upstream.

Ubuntu is now providing an easy way to test these things so that bugs
can be found. That's the purpose of testing. Plus, the last time
something like this happened, it was a real bug in Compiz that was
uncovered by a specific
The Fedora bug for this problem has a patch here:
https://bugzilla.redhat.com/show_bug.cgi?id=537065#c53 . I've been
running with the patch on my work machine which had the same problem for
