NAME

       glint - GLINT/Permedia video driver

         Driver "glint"

DESCRIPTION

       glint  is  an Xorg driver for 3Dlabs & Texas Instruments GLINT/Permedia
       based video cards. The driver is rather fully accelerated, and provides
       support  for  the  following  framebuffer  depths:  8, 15 (may give bad
       results with FBDev support), 16, 24 (32 bpp  recommended,  24  bpp  has
       problems), 30, and an 8+24 overlay mode.


SUPPORTED HARDWARE

       The  glint  driver supports 3Dlabs (GLINT MX, GLINT 500TX, GLINT 300SX,
       GLINT GAMMA, GLINT DELTA, GLINT GAMMA2, Permedia, Permedia 2,  Permedia
       2v,  Permedia  3,  R3, R4) and Texas Instruments (Permedia, Permedia 2)
       chips.


CONFIGURATION DETAILS

       Please refer to xorg.conf(5) for general configuration  details.   This
       section only covers configuration details specific to this driver.

       The  driver  auto-detects  the  chipset type, but the following ChipSet
       names may optionally be specified in the config file "Device"  section,
       and will override the auto-detection:

           "ti_pm2",  "ti_pm",  "r4",  "pm3",  "pm2v",  "pm2",  "pm", "300sx",
           "500tx", "mx", "gamma", "gamma2", "delta"

       The driver will try to auto-detect the amount of video  memory  present
       for  all  chips.   If it's not detected correctly, the actual amount of
       video memory should be specified with a VideoRam entry  in  the  config
       file "Device" section.

       Additionally,  you  may  need to specify the bus ID of your card with a
       BusID entry in the config file "Device" section, especially with  FBDev
       support.

       The following driver Options are supported:

       Option "UseFlatPanel" "boolean"
              Enable the FlatPanel feature on the Permedia3.  Default: off.

       Option "SWCursor" "boolean"
              Enable  or  disable  the  SW cursor.  Default: off.  This option
              disables the HWCursor option and vice versa.

       Option "NoAccel" "boolean"
              Disable  or  enable  acceleration.   Default:  acceleration   is
              enabled.

       Option "Overlay"
              Enable  8+24  overlay  mode.   Only appropriate for depth 24, 32
              bpp.  (Note: This hasn't been  tested  with  FBDev  support  and
              probably  won't  work.)   Recognized values are: "8,24", "24,8".
              Default: off.

       Option "PciRetry" "boolean"
              Enable or disable PCI retries.  (Note: This  doesn't  work  with
              Permedia2 based cards for Amigas.)  Default: off.

       Option "ShadowFB" "boolean"
              Enable  or  disable use of the shadow framebuffer layer.  (Note:
              This disables hardware acceleration.)  Default: off.

       Option "UseFBDev" "boolean"
              Enable or disable use of an OS-specific fb interface  (which  is
              not  supported on all OSs).  See fbdevhw(4) for further informa-
              tion.  Default: off.

       Option "BlockWrite" "boolean"
              Enable or disable block writes for the various Permedia 2 chips.
              This  improves acceleration in general, but disables it for some
              special cases.  Default: off.

       Option "FireGL3000" "boolean"
              If you have a card of the same name,  turn  this  on.   Default:
              off.
