I'd first try to use "xrandr" and see how it manages. This is the guide I use when I have to play with the tool: https://wiki.ubuntu.com/X/Config/Resolution#How_to_setup_a_dual_monitor Debian "X-patrol" team :-) has a also a good guide: http://pkg-xorg.alioth.debian.org/howto/use-xrandr.html Depending on the DE/WM you are using, you can also configure this from a GUI utility (at least both GNOME and KDE do have one). > Both monitors work properly with Knoppix 6.4.4.

Mmm, "radeontool" is an (sic) "utility to control ATI Radeon backlight functions on laptops" so I guess that having this installed or not won't make any difference. > Any ideas why one monitor always goes blank in Squeeze? If you want to use a static xorg.conf file, you can try to define a xinerama setup from there. First, ensure the xserver has loaded the extension correctly: sm01@stt008:~$ grep -i xinerama /var/log/Xorg.0.log (II) Initializing built-in extension XINERAMA And then try to add the required stanza... IIRC, I had to Google a bit to find a working configuration file for my dual-head nvidia card, but you can find many samples out there, for instance: https://help.ubuntu.com/community/XineramaHowTo#ATI Hint: keep your xorg.conf file as small as possible.
