[ltp] Thinkpad and Monitor

I found that I have to use different X server settings for internal lcd
and external monitor, so I ended up using different XF86Config files and 
select the appropriate one in the script that starts X.  

The difference is in the device section.  

For the external display I have:

Section "Device"
    Identifier  "My Video Card"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Option     "extern_disp"
    Option     "no_stretch"
EndSection

For the internal lcd:

Section "Device"
    Identifier  "My Video Card"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Option     "intern_disp"
    Option     "no_stretch"
EndSection


The disadvantage of my setup is that you have to quit and restart X each
time you switch from lcd to the monitor and vice versa.

Actually, if you run with the lcd setup it is possible (at least for me) 
to switch to external monitor with Fn-F7, but the refresh rate is so
crappy that this is not a very good option.

If anyone else has a better solution, I'd love to hear it.

Marat.
