	Aha! I did think of the possibility, of course after I posted -- 
esprit d'escalier <sigh> It's good to know it's a reasonable thought. 
Thanks!

	It seems the T30 was made with two LCDs, both the same size, but 
one 1024x768 (which is what's in xorg.conf now), and the other 1400x1050; 
I've asked on a Thinkpad list how to tell which I have. (I bought it 
reconditioned from IBM.)

	If that's no answer, I'll try fiddling drivers. xorg.conf lists 
"radeon" for the videocard (unidentified) and the option "dpms" in the 
monitor section, but no driver listed there.

	OK

	Yes. I've been running package kit, a/o yum clean all followed by 
yum update, pretty much daily since the upgrade from F10 to F11.

	Hmmm.... I did cd /var/log and then cat Xorg.0.log|most. 
Scrolling down till I hit the word "driver" I get a humongous list -- 
several screens' worth -- without an indication I can recognize to tell 
me which. How do I ask it which it's using?

	Hmmm...! No, I didn't know that. I did it, using ssh -X, and then 
gave the CLI command to launch the map software. It gave me a few lines 
that seemed quite similar to those I get on my #1 PC, if not the same -- 
and then suddenly went to the blank monitor.

	I then gave the same command [viz env WINEPREFIX="/home/
btth/.wine" wine "C:\Garmin\MapSource.exe"] from my #1 PC (where I 
already had an ssh -X connection open). The command sat there in the 
terminal for some time, then opened the map display -- with the swaths 
along the right and bottom of its window. (Btw, I don't *think* I've seen 
those swaths on the T30 itself, when it opens the display at all. But I 
don't swear.)

I have precious (very precious!) little idea where up is.
