I seem to remember there was a change of the default acceleration method in
the Intel driver a while back (on Arch) to SNA which caused some problems
on old Intel laptops for me. I definitely have one with 915 graphics, and I
think it was affected (it's retired now so I can't check).

Perhaps this change has recently appeared in the Debian world too?
