The xorg logs for both Manolo and Ride show you are using the old Jaunty kernel (2.6.28) and drm is not properly working. Please make sure you boot with the new Karmic kernel (2.6.31) and see if that solves the problem.
If the karmic kernel still has this problem, please attach xorg.0.log and dmesg output with the Karmic kernel.
