I'm trying to run Ubuntu linux on a machine with an Abit Siluro FX5200. The display is an Acer flat panel with 1680x1050 native resolution.

nvidia-settings tells me the monitor reports the native resolution as being 1280x1024 and provides this as the maximum resolution.

I've tried both the nv and nvidia drivers. Both limit the maximum resolution to 1280x1024.

The thing is, I used to run a 21" Sony monitor at 1600x1200 on this exact box so I know this video card can do more.

How can I get this thing running at 1680x1024?


Any help would be appreciated.

The problem is that a 1680x1050 resolution goes beyond the
maximum pixel clock of 135MHz for the FX5200. I had one, and
irrc, could get to 1680x1050 by putting this in xorg.conf:
However, I could not find out if that might damage the card,
so I just bought a GeForce 7300 GT which gets that resolution
without any hack.

If that's not the option that works, you can Google and you
will find which one does. My recommendation is to buy a new
digital card that can do that resolution natively.
