Where we really need feedback is from the field. Some of the worst touchpad issues I have seen are in a school deployment in Lima. Perhaps Hernan's team at USMP could do some testing? (FWIW, I am still of the opinion that we may want to disable the touchpad on the old hardware and re-enable the resistive pad, which should be more immune to some of the problems we have been experiencing.) regards. -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
