Try turning off ide DMA I keep getting emails from people which have seen my post. To all of them (and everyone else): There's an undocumented bit in an undocumented register in the built-in graphics device of Intel's i810 (i815?) chipset (GMCH). Setting that bit to a 1 solved out this problem (which someone affectuously called 'the damn blinking problem'). Get the code at http://www.cl.cam.ac.uk/~pb/wmi810.tar.gz , compile, install, read the README/INSTALL. It's as simple as that. To everyone who has tried to help in this mailing list, my apollogies. This should be fixed in the XFree driver (I hope it'll be fixed in the next release). Also, my thanks to every single one who tried to help. ---- Ricardo Manuel Oliveira Eurotux Informática, SA Tel: +351 253257395 // +351 919475934 Fax: +351 253257396
