On my Ubuntu 6.10 notebook (1400x1050, 60 Hz) the display flickers every now and then when I use the "nvidia" driver (in contrast the preinstalled "nv" default driver works fine). The entire screen contents seem to move a pixel row down and right and back in a split second once a half minute.
Maybe it's just a simple sync problem?
Unfortunately I could't find exactly the same issue in this forum, not to mention a solution.

thanks in advance!
