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. :-) > > I'd like to point out that the nvidia driver comes with > > nice documentation: /usr/local/share/doc/NVIDIA_GLX-1.0/README > > contains lots of great stuff. > > The html version is even nicer to work with: > > file:///usr/local/share/doc/NVIDIA_GLX-1.0/html/index.html 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. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
