Vincent, I also had problems with my laptop that has a Triden Cyber 9525; the screen seems to be okey but after a screensaver start, a change from console to the Xwindows or start again the laptop after resume shutdown the screen become crazy with intense light everywere.
So I had to return to my Mandrake 8.0 with XFree86 4.0.3 and forget the 8.1 with 4.1. My machine is a Toshiba Stellite 4090XCDT with Cyber 9525 (recognized as generic). I have sent a message to XFree bug reports, but after a month I have no answer. Perhaps we can call for all the people runing a linux distribution with XFree 4.1 to report that, I hope the XFree86 team must take care about those chips that are very common on laptops. Any advice mandrake team? Francisco Alcaraz Murcia (Spain)
