Yuk. The list of supported video says that there is a freeze screen bug with i945. So go to bug 445056 and scroll down to bottom. Aha! says that
So go to usr/lib/dri . Nope. i915 and i965 are there, but no i945. Not in dri_alternates, either.As per last comment, this is believed fixed.
Hmm. Spot the documentation on binary drivers . Maybe the answer lies in Xorg.conf.d? says it is in usr/lib/Xll/Xorg.conf.d. No it's not - I guess that assumes I have plugged in something else.
As a newcomer, this is all getting a bit above my pay grade. Is there someone out there who can tell me where the driver is that the hardware support people now believe has its bug fixed?
