## 1.1. Notes

- On the NV1/STG2000, the driver does not support the virtual desktop features 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.
- 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.
- 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 managers in 16bpp, try putting a Weight 555 in the Display section.
- 24 bpp is not supported.
- In some modes the hardware cursor gets out of sync with the display. Use Option "sw_cursor" to work around this problem.
- There are modelines that confuse the Riva128 chip. This results in a greenish display. Slightly modifying the modeline usually fixes the problem. In most cases all that is needed is to reduce the HTotal. You can use xvidtune to do that.
- 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.
