Debian Lenny screen refresh rate
I have a box running Debian Etch, has a 1000MHz Athlon and Geforce 6800 graphics card, monitor is an Iiayama Vision Master Pro 454. This box happily runs at 1280 x 1084 85Hz.
I've built a new system, Intel Q6600 @ 2.4GHz, Geforce 9800 graphics card, same monitor (running through a KVM switch). I've downloaded Debian Lenny, installed an Nvidia kernel but Gnome's screen resolution utility doesn't offer any refresh rate higher than 77Hz for 1280 x 1084 screen size. "dpkg-reconfigure xserver-xorg" never gets as far as configuring the screen, but exits after the keyboard questions. I've got a better CPU and better graphics card, anyone know why I can't get the same performance from my monitor? Old box uses KDM whereas the new one is on Gnome, in case that makes any difference.

Do any of the following commands shed any light ? they should query the monitor for it's capabilities.
xresprobe nvidia ddcprobe get-edid |

Hmm, a quick and dirty solution has been to copy the xorg.conf from the Etch box to the Lenny box, the screen has stopped flickering but the screen resolution utility now only offers a max of 55Hz for a 1280 x 1084 screen.
