+1. XFree86 driver for NVidia NV1 / SGS-Thomson STG2000 and Riva128
+
+This driver supports good acceleration for both the NV1/STG2000 as well as the
+Riva128. It is known to work on PCI and AGP versions of the Riva128.
+
+1.1 Notes
+
+ o On the NV1/STG2000, the driver does not support the virtual desktop fea-
+ tures of xfree86. This is because the NV1 does not have the necessary
+ hardware to support this feature. If you want to change resolutions, you
+ will have to modify your config file. Comment out all but the mode you
+ wish to use.
+
+ o The generic VGA16 server will not work with the NV1. For this reason
+ XF86Setup cannot be used to configure the server. Use xf86config instead.
+ Select `Diamond Edge 3D' as your board, and select only ONE mode for each
+ of 8bpp and 16bpp. Do not select a virtual desktop. Also, make sure you
+ don't select a RAMDAC or clock chip. This does not apply if you own a
+ Riva128 card, as the VGA16 server works just fine on that.
+
+ o Both the NV1 and the Riva128 only support a 555 RGB Weight in 16 bpp, the
+ hardware does not do 565. If you run into problems with some window man-
+ agers in 16bpp, try putting a Weight 555 in the Display section.
+
+ o 24 bpp is not supported.
+
+ o In some modes the hardware cursor gets out of sync with the display. Use
+ Option "sw_cursor" to work around this problem.
+
+ o There are modelines that confuse the Riva128 chip. This results in a
+ greenish display. Slightly modifying the modeline usually fixes the prob-
+ lem. In most cases all that is needed is to reduce the HTotal. You can use
+ xvidtune to do that.
+
+ o The dotclock limits for this driver seem to be lower than the hardware
+ specs (and drivers for other graphical user interfaces) seem to indicate.
+ If you get a flickery screen with flashes, try to limit the modes you use
+ to about 160MHz in 16bpp and about 100MHz in 32bpp.
