Syncmaster 2343BW + ION2

[Buuuh]

Hi,

i bought a nettop with nvidia ion2 and have a samsung syncmaster 2343BW which has native resolution 2048x1152.
I can't get it run in this solution, nvidia cp only lets me configure 640x480.
I have installed nvidia graphics driver 260.19.06 on Ubuntu 10.10 64bit. The monitor is connected via DVI and nvidia cp shows me, that it is a dual link connection. The ION2 only has DVI-D and HDMI. On HDMI with adapters it's the same problem.

I also connected it to my TV via the HDMI port, which runs perfectly with 1360x768.

Additionally i tried already some stuff in the xorg.conf, like adding the Modeline and setting the "UseEDIDFreqs", but all this had no effect.

How can i force X to use/provide the full native solution of the monitor?

Here's the complete xorg.conf:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 260.19.06  (buildd@yellow)  Mon Oct  4 15:59:51 UTC 2010

There's a lot of discussion about this issue with the Asus Eee 1215n, which has Ion 2:

This thread doesn't handle my problem. Nvidia driver works here, it "just" doesn't recognize my samsung monitor.

I got it solved, following xorg.conf did it:

Key was the
Option "ExactModeTimingsDVI" "TRUE"
which forces X to use the given modeline and of course the modeline itself.

thanks BUHHH for sharing the solution - have the same chipset and monitor and you helped a lot
