fedora11 shows two displays but I have one, resolution problem

[pepenet]

Hi,

I install fedora 11 snap1 , and I have a problem with the display configuration.
I have only ONE display, a samsung 20' monitor, but the system-> preference=> display shows me two monitors:
"unknown" max resolution 1024x768
"Samsumg 20''' max resolution 1680x1050

when I click in "detect monitors" in the samsung monitor (my unique monitor) show me the 'unknown' and only can set it to 1024x768.

Is like X swap the monitors configuration in running configuration

may you helpme?


the xrand shows:
