I'm currently using that driver, and everything seems to
work as intended. The only problem I have is that the
driver has different DPI opinions as the previous ones.
This makes some fonts unreadable. I found that I can
easily change the Gtk+ base font by a ~/.gtkrc-2.0
with something like ``gtk-font-name="Tahoma 12"'' in
it, but this of course doesn't apply everywhere.
There seems to be a solution to handle DPI settings in
X directly, so I put "DisplaySize 410 305" in the monitor
section of xorg.conf. The monitor is an Eizo FlexScan F980
21" CRT with BNC cabling, so no autodetect magic. But some
things still are wrong, maybe I should try ``Option "DPI"
"96 x 96"'' in the device section - I'm not sure which
values should be used, 72 or 75 or 96 or 115...
Additionally, the gv program has a problem (but it already
had that on _each_ of the three drivers): The keys for
selecting pages are squished.
This is how they should look like:
http://t16web.lanl.gov/Kawano/gnuplot/intro/plotcalc7.png
They are like this:
+-----+ +-----+ +-----+ +-----+
|* ===| | ===| | ===| | ===|
| ===| |* ===| | ===| | ===|
|* ===| | ===| |* ===| | ===|
| ===| |* ===| | ===| | ===|
+-----+ +-----+ +-----+ +-----+
SHOULD like. Currently, they look like this:
+-----+ +-----+ +-----+ +-----+
|#####| |#####| |#####| |#####|
+-----+ +-----+ +-----+ +-----+
You can't tell which is which.
The gv program uses Xaw3d for the display elements. Maybe nVidia
is not compatible with that? Or it's also a "wrong DPI" effect?
Everything else in gv works as intended.
On the other hand, mplayer can now change brightness and contrast
again; I have put "vo=gl" in ~/.mplayer/config and it works. :-)

Thanks for the pointer, yes, that's really informative. During
the near future, I'm interested in getting Twinview + Xinerama
working (as I actually have _two_ 21" CRTs of the same type)
and TV out working.
