glint - GLINT/Permedia video driver
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.
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)
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
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
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".
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
information. 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:
Xorg(1), xorg.conf(5), Xserver(1), X(7)
