[Novalug] screen resolution for an LCD screen

In trying to get my LCD screen to run at the best mode,
=680x1050, I installed an ATI Radeon HD 3450 card.
This doesn't solve the problem, unfortunately: it
still runs in 800x600 mode.
The videocard is there. To find it, I followed a
suggestion from the list:
sudo lshw > list-of-hardware
product: M2N-MX SE
vendor: ASUSTeK Computer INC.
description: PCI bridge
product: MCP61 PCI Express bridge
vendor: nVidia Corporation
physical id: 9
bus info: pci at 0000:00:09.0
width: 32 bits
capabilities: pci pm msi ht pciexpress normal_decode
description: VGA compatible controller
product: Mobilitiy Radeon HD 3450
vendor: ATI Technologies Inc
physical id: 0
bus info: pci at 0000:02:00.0
width: 64 bits
capabilities: pm pciexpress msi vga_controller bus_master
The only thing I see possibly wrong here is 'display UNCLAIMED'.
What could be another place to look for a problem? I did notice
that X uses /etc/X11/xorg.conf.failsafe', which only contained
the resolution the monitor uses, viz., 800x600. I added the mode
that I want in the line 'Modes' (now, Modes "1680x1050" "800x600"),
but this didn't help: it actually made it worse, since now the
screen goes to 640x480.
Any insight you can offer is most welcome.
