Hey,

I had similar messages on a Thinkpad r51 in which I came back from
sleep. Things worked enough to have a mouse move around, to be able to
switch virtual terminals, even to login if I could guess where to click,
but none of the widgets would get drawn on X anymore.

I did not solve the bug in time to enjoy lucid but have solved it for maverick by finding this kernel bug report:
    https://bugzilla.kernel.org/show_bug.cgi?id=15969

I changed the line in /etc/default/grub
    GRUB_CMDLINE_LINUX=""
to read
    GRUB_CMDLINE_LINUX="radeon.agpmode=-1"
and now both sleep and hibernate come back correctly.

I have no idea how to ask the Ubuntu kernel folk if they have included
the patch that avoids this workaround.

hope that helps someone,
--adrian
