Mine is N455 GMA 3150. Maybe all GMA Intel GPUs are affected?
GMA 900 (910G, 915G, 915Gx)
GMA 950 (945G)
GMA 3100 (Q33, G35, G31, G33)
GMA 3150 (Atom D4xx, D5xx, N4xx, N5xx)
("SNA" seems to stand for "Sandybridge's New Acceleration").

I've surveyed how we can change xorg.conf simpler, and then
it's turned out it's enough to have the following simple
/etc/X11/xorg.conf just to change only the "AccelMethod":
Identifier "Intel Gen3 GPU workaround"
Option "AccelMethod" "uxa"
Maybe we should an independent section about the trouble shooting?
