- 1. Supported hardware
-
- This server supports the following 3DLabs chipsets:
-
- o GLINT 500TX with IBM RGB526 RAMDAC
-
- o GLINT MX with IBM RGB526 and IBM RGB640 RAMDAC
-
- o Permedia with IBM RGB526 RAMDAC
-
- o Permedia 2 (classic, 2a, 2v)
-
-
- 2. Features
-
- o accelerated
-
- o hardware cursor
-
- o DPMS support
-
- o supported color depths
-
- o GLINT MX/500TX: 8/16/32 bpp
-
- o Permedia: 8/16/32 bpp
-
- o Permedia 2: 8/16/24/32 bpp
-
-
- 3. XF86Config Option
-
- Option "sw_cursor"
- disable the hardware cursor.
-
- Option "no_pixmap_cache"
- disables use of the pixmap cache. Might be useful if drawing errors
- occur.
-
- Option "no_accel"
- completely disables acceleration. Usually not recommended.
-
- Option "pci_retry"
- stall the PCI bus while the graphics engine is busy. While this

- might give slightly higher performance, you run the risk of dis-
- turbing other devices that are waiting to be serviced by the pro-
- cessor. This option may cause problems with SCSI cards, serial con-
- nections, sound cards, etc.
-
- Option "firegl_3000"
- needed for the Diamond Fire GL 3000 in order to use the primary
- output on that card. The second screen is currently not supported.
-
- Option "overclock_mem"
- Run the memory at a higher clock. Useful on some cards with display
- glitches at higher resolutions. But adds the risk to damage the
- hardware. Use with caution.
-
-
- 4. Bugs and Limitations
-
- o The 500TX and MX chipsets cannot switch modes, therefore only the first
- mode on the modes line is available.
-
- o In some color depths without acceleration there are color problems.
-
- o While the server is accelerated, there is room for improvement. As our
- development is focusing on XFree86-4.0 we are not planning to change that
- in the 3.3.x branch. XFree86-4.0 will include a significantly faster
- server.
