I seem to have this same problem, using Ubuntu hardy package xserver-xorg-video-intel 2:2.2.1-1ubuntu12.

I have not tried changing the FramebufferCompression option yet.

One thing I have noticed is that the problem does not start for me until *after* the first time the screen is blanked by the power management. I don't know if that is useful information, but I haven't seen it mentioned before. Once it starts, it happens pretty regularly every 2 minutes or so (but I don't believe it's a fixed pattern).

Actually, I only see lines referring to 'fbc enabled' after the first power management screen blanking, so maybe that's the connection. Sorry, but I'm not really familiar with what the framebuffer compression is supposed to be doing.

I'm seeing this on an external Samsung SyncMaster 220WM 22" LCD at 1680x1050 connected to a Dell Inspiron e1405 with Intel 945GM graphics.

Thanks...
