  Driver qglintq


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) chips.


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 qDeviceq 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 qDeviceq section.

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

The following driver Options are supported:

Option qUseFlatPanelq qbooleanq
Enable the FlatPanel feature on the Permedia3. Default: off.
Option qSWCursorq qbooleanq
Enable or disable the SW cursor. Default: off. This option disables the HWCursor option and vice versa.
Option qNoAccelq qbooleanq
Disable or enable acceleration. Default: acceleration is enabled.
Option qOverlayq
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 qPciRetryq qbooleanq
Enable or disable PCI retries. (Note: This doesn't work with Permedia2 based cards for Amigas.) Default: off.
Option qShadowFBq qbooleanq
Enable or disable use of the shadow framebuffer layer. (Note: This disables hardware acceleration.) Default: off.
Option qUseFBDevq qbooleanq
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 qRGBbitsq qintegerq
Each gun of the RGB triple can have either 8 or 10 bits. Default: 8
Option qBlockWriteq qbooleanq
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 qFireGL3000q qbooleanq
If you have a card of the same name, turn this on. Default: off.
