I am trying to install x86_64 on a compaq r4000 laptop. booting the CD I have tried text mode only and graphicaly mode. I see the normal stuff flying by and I just get a black screen (in text for graphic install). I have tried linux acpi=off apci=off nousb nopcmcia linux noprobe all result in the same black screen. Once the screen goes black the CD is still being accessed but the screen is just black. I have tried CTRL-ALT-F1 or F2 and still nothing. CTL-ALT-DEL does reboot the machine. Anyone seen this? any ideas? the machine is compaq r4000, turian 64 bit cpu. ATI video. windows on the same machine works fine. jerry
