96 Disables DDC (Display Data Channel) so that the Xserver doesn't try to talk to\
98 Default: off, implies DDC is used.
101 Disables use of DDC version 1 (DDC using vertical refresh). \
102 Default: off, implies DDC1 is used.
105 Disables use of DDC version 2 (DDC using I2C - usually over vga connector). \
106 Default: off, implies DDC2 is used.
111 The framebuffer device to use. \
115 Enable or disable use of the shadow framebuffer layer. \
119 Enable rotation of the display. The supported values are "CW" (clockwise, \
120 90 degrees), "UD" (upside down, 180 degrees) and "CCW" (counter clockwise, \
121 270 degrees). Implies use of the shadow framebuffer layer. \
127 Set the colormap index used for the transparency key for the depth 8 plane \
128 when operating in 8+24 overlay mode. The value must be in the range 2-255. \
132 !Enable or disable the HW cursor. Default: on.
135 Specify whether G100, G200 or G400 cards have SDRAM. The driver attempts to \
136 auto-detect this based on the card's PCI subsystem ID. This option may be \
137 used to override that auto-detection. The mga driver is not able to \
138 auto-detect the presence of of SDRAM on secondary heads in multihead \
139 configurations so this option will often need to be specified in multihead \
140 configurations. Default: auto-detected.
143 Disable or enable 2D hardware acceleration. Default: acceleration is enabled.
146 Set clocks to values used by some commercial X-Servers (G100, G200 and \
147 G400 only). Default: off.
150 Enable 8+24 overlay mode. Only appropriate for depth 24. (Note: the G100 is \
151 unaccelerated in the 8+24 overlay mode due to a missing hardware feature). \

159 Default: no rotation.
162 Enable or disable use of the shadow framebuffer layer. Default: off. \
165 Enable or disable combining the sync signals with the green signal. \
169 Enable or disable use of on OS-specific fb interface (and is not supported \
170 on all OSs). See fbdevhw(4) for further information. Default: off.
173 This sets the default pixel value for the YUV video overlay key. \
177 This has XvImage support use the texture engine rather than the video \
178 overlay. This option is only supported by the G200 and G400, and only in \
179 16 and 32 bits per pixel. Default: off.
182 Matrox provides a "Hardware Abstraction Layer", \
183 a separate binary which enables extra hardware features from G400 onwards. \
184 Default: HAL is used.
187 ! Option Ignored. Drivers auto-detect Digital output if they support it at all.
188 !Default: Auto-detected.
191 ! Option Ignored. Drivers auto-detect TV if they support TV out at all.
192 !Default: Auto-detected.
195 (HAL only) Picture standard for TV out. Use "PAL" for 50Hz PAL. \
199 (HAL only) Set the cable type for TV out. Options are "SCART_RGB", \
200 "SCART_COMPOSITE", or "SCART_TYPE2". Any other string enables the default. \
201 Default: YC_COMPOSITE.
204 (HAL only) For Dual Head cards, reverse relationship between CRTC picture \
205 generators and video output sockets. \
206 Especially useful with TV or digital outputs. \
207 Default: CRTC1 generates output for socket 1 and CRTC2 generates output for socket 2.
210 In dual head mode, allow CRTC2 to use half of the video memory. \
211 Default: CRTC2 uses min{8MB, half video RAM}, but see also Crtc2Ram.
214 In dual head mode, CRTC2 will use this many KB of video memory. \
215 Overrrides Crtc2Half. \
216 Default: CRTC2 uses min{8MB, half video RAM}, but see also Crtc2Half.
219 An option for hackers. The pixmap cache lives in off-screen video memory. \
220 This option extends the virtual desktop to show this part of video memory. \
224 AGP bus speed multiplier, used by DRI. \
225 Default: x1 (slowest but most stable).
231 !Selects software cursor. \
235 Enables or disables all hardware acceleration. \
239 Enables or disables the use of 6 bits per color component when in 8 bpp \
240 mode (emulates VGA mode). \
244 This overrides the default pixel value for the YUV video overlay key. \
248 Select display mode for devices which support flat panels. Supported\
249 modes are "FP", "CRT", "Mirror", "BIOS". \
253 Enable or disable programming of the flat panel registers.\
254 Beware that this may damage your panel, so use at your own risk. \
255 Default: device dependant.
258 Override flat panel width in pixels. \
259 Default: determined using BIOS.
262 Override flat panel height in pixels. \
263 Default: determined using BIOS.
266 Enable or disable use of on OS-specific fb interface (and is not supported \
267 on all OSs). See fbdevhw(4) for further information. Default: off.
270 Try or don't try to use DMA for Xv image transfers. This will reduce CPU \
271 usage when playing big videos like DVDs, but may cause instabilities. \
278 Selects software cursor. Default: off.
281 Disables all hardware acceleration. Default: off.
284 Enables or disables the use of 6 bits per color component when in 8 bpp \
285 mode (emulates VGA mode). Default: off.
288 This overrides the default pixel value for the YUV video overlay key. \
292 Enable or disable use of an OS-specific framebuffer device interface \
293 (which is not supported on all OSs). Default: off.
296 Set AGP data transfer rate. (used only when DRI is enabled) \
297 Valid choices: 1 (default), 2 and 4
299 radeon.AGPFastWrite:\
300 Enable AGP fast write. (used only when DRI is enabled) \
303 radeon.ForcePCIMode:\
304 Force to use PCI GART for DRI acceleration. (used only when DRI is enabled) \
308 Force to use the modes queried from the connected monitor. Default: off.
310 radeon.CloneDisplay:\
311 This option is only used for dual-head cards with only single screen section \
312 specified in the configuration file. Valid choices: \
313 0 - disable (one CRTC used for both heads) \
314 1 - auto-detect (default) \
316 3 - auto-detect + 2nd head overlay \
317 4 - force on + 2nd head overlay \
320 Set the first mode for the secondary head. It can be different from the modes \
321 used for the primary head. If you don't have this line while clone is on, the \
322 modes specified for the primary head will be used for the secondary head.
325 Set the horizontal sync range for the secondary monitor. It is not required if \
326 a DDC capable monitor is connected. Default: undefined.
328 radeon.CloneVRefresh:\
329 Set the vertical refresh range for the secondary monitor. It is not required \
330 if a DDC capable monitor is connected. Default: undefined.
333 Disable panel output. Only used when clone is enabled. Default: off.
335 radeon.EnablePageFlip:\
336 Enable page flipping for 3D acceleration. This will increase performance but \
337 not work correctly in some rare cases. Default: off.
343 Before XFree86 version 4.2.0 many NeoMagic systems experienced \
344 strange lockups unless they used the options \
345 "XaaNoScanlineImageWriteRect" and "XaaNoScanlineCPUToScreenColorExpandFill". \
346 Setting this to "No" is faster but will lock some machines. \
351 Enable or disable use of the shadow framebuffer layer. See shadowfb(4)\
352 for further information. Default: on.
357 Disable or enable acceleration. \
358 Default: acceleration is enabled.
