[ltp] Goodbye to Linux on my Thinkpad :-(

[Phil]

Which config? There are several on thinkwiki. I've tried several,  the 
one that looks most promising is at 
http://thinkwiki.org/wiki/Additional_options_for_the_radeon_driver
However using this my external stays resolutely blank (although it is 
getting signal). The desktop shows multiple screen but if I drag windows 
over to the external they don't show.
Does the bios monitor setting make any difference?
I'd be grateful for a copy of your xorg.conf. Mine is below - I've 
commented out the second monitor settings and laptop screen runs nicely 
in high res.
Cheers
Phil
