Hi Mike, could you try to apply patch available at ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/matroxfb.gz? It has some fixes in cursor blinking code, but, I must admit, nothing which could fix problem you are reporting... Now I tried it (my teletext grabber uses ncurses and prints each page number it receives) and after holding 'shift-pgup' for some time (more than 15 seconds of strange picture blinks...) it stopped scrolling, but cursor was still blinking... After I hit shift-pgdn, machine died :-( So simple do not do it until I did not find what's going on, sorry. Best regards, Petr Vandrovec vandrove@vc.cvut.cz
P.S.: All ideas welcomed...
