Unable to configure NEC LCD22WV in CentOS 5.2 [Thinkpad A31]


Hi All,
I am newbie in Linux. I have just installed CentOS 5.2 into my laptop and
got everything working. But except my external monitor not being able to setup correctly. It is only allowing me to set three resolutions 1024x768, 800x600, 640x480 which are valid for the laptop's screen.

I have tried to modify xorg.conf using "Xorg -configure" but even with that I am unable to get it working. BTW, I do not see xorgconfig or xorgcfg [ both leads to "Command not found" error, locate couldn't locate.]

Please note that my monitor is connected to the laptop via docking station.

I am trying to get it working for last 24 hours or so.

Please let me know how I should proceed or any pointer ?

Thanks,
NxG
