I have a Lenovo X201 laptop with an i7-620M processor. After I resume
from a Suspend to RAM the graphics are very slow. Suspend to Disk does
not cause the same problem and doing a Suspend to Disk after a Suspend
to RAM fixes the problem.
I see the same slow-down regardless of whether X11 is running or not.
I'm not doing 3D, I notice the slow-down in regular 2D stuff like
scrolling a lot of text through a terminal window. When X11 is running
I see the same problem whether I'm using the laptop's display or an
external displayport monitor. I've tried a 2.6.36 kernel and the
Any help in tracking down this problem would be appreciated, Thanks.
