Hi Luis, Try an older kernel first, 2.6.27 or there abouts. I've experienced similar but worse here. As soon as my machine hits it's screen blanking power save time out, input completely fails but processes still run. I guess it's an xorg kernel driver bug related to the framebuffer driver. Reverting back to an older kernel might mean you miss the commit that causes it. Maybe even try a different framebuffer driver.
