i get the boot up black screen problem when running off the live cd of bt3beta.. i tried acpi=off and noapic.. but had no luck. tried vesa and flux too.. no luck. in text mode i says it cant find screens. im running an acer extensa 4420 wuth an ati radeonx1250 graphics card. maybe xorgconfig will work? idk how to work it... but if you think its something else let me know. ill keep searching the forums as well, thanks for any help
