5) Configuration
|
|
|
|
|
|
|
|
|
|
The driver auto-detects all device info included memory size, so
|
|
|
|
|
use the following device section in your XF86Config file:
|
|
|
|
|
|
|
|
|
|
Section "Device"
|
|
|
|
|
Identifier "NeoMagic"
|
|
|
|
|
EndSection
|
|
|
|
|
|
|
|
|
|
or let xf86config or XF86Setup do this for you.
|
|
|
|
|
|
|
|
|
|
But if you have problems with auto-detection, you can specify:
|
|
|
|
|
|
|
|
|
|
VideoRam - in kilobytes
|
|
|
|
|
DacSpeed - in MHz
|
|
|
|
|
MemBase - physical address of the linear framebuffer
|
|
|
|
|
IOBase - physical address of the memory mapped IO registers
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
6) Driver Options
|
|
|
|
|
|
|
|
|
|
"no_linear" - banked framebuffer mode
|
|
|
|
|
"no_accel" - software rendering only
|
|
|
|
|
"sw_cursor" - software cursor only
|
|
|
|
|
"no_mmio" - use I/O space directly
|
|
|
|
|
"intern_disp" - enable internal display (default)
|
|
|
|
|
"extern_disp" - enable external display
|
|
|

|
|
|
|
|
"lcd_center" - center lower resolution modes on panel
|
|
|
|
|
|
|
|
|
|
NOTE: Stretching of panel image is on by default for lower panel
|
|
|
|
|
resolutions.
|
|
|
|
|
|
|
|
|
|
Options useful for special lcd mode setting (should not be needed):
|
|
|
|
|
"prog_lcd_mode_regs" - set special lcd mode registers (2070 default)
|
|
|
|
|

|
|
|
|
|
"prog_lcd_mode_stretch" - force lcd mode regs if stretching is enabled
|
|
|
|
|
"no_prog_lcd_mode_stretch" - no lcd mode regs if stretching (default)
|
|
|
|
|
|
|
|
|
|
Option for subnotebooks and other laptops with uncommon size panels:
|
|
|
|
|
"override_validate_mode" - disable LCD mode checking
|
|
|
|
|
|
|
|
|
|
WARNING: Disabling mode checking will allow for invalid modes that
|
|
|
|
|
could damage your LCD.
