Is the effect a beat that it has roughly the frequency of your Notebooks screen refresh rate (60Hz)? (in german: Schwebung) > The effect is so nice that I thought about youtube ;-). Thinkpad > x60.. question is, how to debug it? No idea... check where the register of the HW cursor blink rate gets written? But as it seems to be so nice, please submit a patch which enables this for all platforms. ;-) Regards, -- Clemens Koller _______________________________ R&D Imaging Devices Anagramm GmbH Rupert-Mayer-Str. 45/1 81379 Muenchen Germany http://www.anagramm-technology.com Phone: +49-89-741518-50 Fax: +49-89-741518-19
