Sleepy X after today's rawhide update

[Andrew Parker]

After today's updates, I find that if I don't press a key or move the
mouse for 2-5 seconds then the display freezes until I generate some
input.

Its rather like a ^S for X.  Its not that the display doesn't get
updated, the processes generating output get held up, then continue as
soon as I generate input.

This happens immediately on login, so the login never completes unless
I waggle the mouse.

Curiously, a screensaver that I tried doesn't suffer from the same problem.

This is on a Dell Inspiron 1410 laptop which has the following display adapter:

00:02.1 Display controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)
