5. Configuration
|
|
|
|
The driver auto-detects all device information necessary to initialize
|
|
the card. The only lines you need in the "Device" section of your
|
|
xorg.conf file are:
|
|
|
|
Section "Device"
|
|
Identifier "Intel i740"
|
|
Driver "i740"
|
|
EndSection
|
|
|
|
|
|
|
|
However, if you have problems with auto-detection, you can specify:
|
|
|
|
o VideoRam - in kilobytes
|
|
|
|
o DacSpeed - in MHz
|
|
|
|
o MemBase - physical address of the linear framebuffer
|
|
|
|
o IOBase - physical address of the memory mapped IO registers
|
|
|
|
|
|
|
|
6. Driver Options
|
|
|
|
|
|
o "NoAccel" - Turn off hardware acceleration
|
|
|
|
o "SWCursor" - Request a software cursor (hardware is default)
|
|
|
|
o "SDRAM" - Force the use of SDRAM timings
|
|
|
|
o "SGRAM" - Force the use of SGRAM timings
|
|
|
|
o "SlowRam" - Force the use of slower ram timings
|
|
|
|
o "Dac6Bit" - Force the use of a 6 Bit Dac (8 Bit is the default)
|
|
|
|
o "UsePIO - Force the use of programmed IO (Memory mapped is the
|
|
default)
|
|
|
|
Note: the i740 X server should automatically detect whether your card
|
|
has SGRAM or SDRAM. Use the "sgram" and "sdram" options if it is
|
|
incorrectly detected.
|
|
|
|
|
|
|
|
7. Known Limitations
|
|
|
|
|
|
o Certain drawing operations are very slow when using 24 bit pixel
|
|
depth mode.
