Identifier sa carte graphique avec lspci Pour cela il suffit de taper dans votre terminal la commande suivante: lspci -nn grep VGA La commande doit renvoyer quelque chose dans ce style: Pour savoir dans quelle famille de pilotes se trouve votre carte, reportez-vous à ce tableau. Ici il s'agit donc du pilote R qui s'occupe de la puce RV Et en fonction de cela, vous pouvez savoir quelles sont les fonctionnalités supportées par le tout dernier pilotes, en lisant la page Radeon Feature. Certaines font déjà partie des spécifications d'OpenGL 3, mais comme il en manque quand même, le support complet n'est valable que pour la version 2. La liste ci-dessus vous aidera peut être à comprendre laquelle.

Option "DisplayPriority" "string" Used to prevent flickering or tearing problem caused by display buffer underflow. AUTO -- Driver calculated default. Use this if the calculation is not correct for your card.

HIGH -- Force to the highest priority. Use this if you have problem with above options. This may affect performance slightly. The default value is AUTO. Option "ColorTiling" "boolean" Frame buffer can be addressed either in linear or tiled mode.

Tiled mode can provide significant performance benefits with 3D applications, for 2D it shouldn't matter much. Tiling will be disabled if the virtual x resolution exceeds for R and above , or if DRI is enabled the drm module is too old. If this option is enabled, a new dri driver is required for direct rendering too.

Color tiling will be automatically disabled in interlaced or doublescan screen modes. The default value is on. This is different from NoDDC option. The default value is off. Also overrides DDC monitor detection. You may specify a semicolon separated list of output name and filename pairs with an optional flag, "digital" or "analog", to override the digital bit in the edid which is used by the driver to determine whether to use the analog or digital encoder associated with a DVI-I port.

The output name is the randr output name, e. The file must contain a raw byte EDID block, as captured by get-edid. Note that a output name must always be specified, even if only one EDID is specified. Caution: Specifying an EDID that doesn't exactly match your display may damage your hardware, as it allows the driver to specify timings beyond the capabilities of your display.

Use with care. Option "PanelSize" "string" Should only be used when driver cannot detect the correct panel size. If you have a panel with timings different from that of a standard VESA mode, you have to provide this information through the Modeline. For example, Option "PanelSize" "x" The default value is none.

This will increase performance but not work correctly in some rare cases, hence the default is off. Some Radeon BIOSes report a minimum dot clock unsuitable too high for use with television sets even when they actually can produce lower dot clocks.

If this is the case you can override the value here. Note that using this option may damage your hardware. You have been warned. The frequency parameter may be specified as a float value with standard suffixes like "k", "kHz", "M", "MHz". Option "RenderAccel" "boolean" Enables or disables hardware Render acceleration. The default is to enable Render acceleration. Option "AccelMethod" "string" Chooses between available acceleration architectures.

XAA is the traditional acceleration architecture and support for it is very stable. EXA is a newer acceleration architecture with better performance for the Render and Composite extensions. The default is EXA. With XAA, specifying lower percentage than what gets reserved without this option has no effect, but the driver tries to increase the video RAM reserved for textures to the amount specified roughly.

Default: Option "DepthBits" "integer" Precision in bits per pixel of the shared depth buffer used for 3D acceleration. Valid values are 16 and Default: The same as the screen depth.

Default: on. Option "SubPixelOrder" "string" Force subpixel order to specified order. Subpixel order is used for subpixel decimation on flat panels. The default subpixel order is incorrect for your panel. Enable subpixel decimation on analog panels. Adjust to one display type in dual-head clone mode setup.

This can help reduce heat and increase battery life by reducing power usage. Some users report reduced 3D performance with this enabled. The default is off. This can help reduce heat and increase battery life by reducing power usage at the expense of performance. Option "DynamicPM" "boolean" Enable dynamic power mode switching. This can help reduce heat and increase battery life by reducing power usage when the system is idle DPMS active.

This is necessary for properly resuming consoles when in VGA text mode, but shouldn't be if the console is using radeonfb or some other graphic mode driver. Some platforms like PowerPC have issues with those, and they aren't necessary unless you have a real text mode in console.

Use this if the X server obviously detects the wrong display for each connector. This is typically needed on the Radeon cards bundled with Apple G5s. This option will force probing of the current value programmed in the chip when X is launched in that case.

This is only useful for LVDS panels laptop internal panels. The default is on. This option has no effect on Mac cards. Enable this option if you are having problems with a washed out display on the secondary DAC. This option allows you to enable to disable the DRI. The default is off Option "MacModel" "string" Used to specify Mac models for connector tables and quirks. If you have a powerbook or mini with DVI that does not work properly, try the alternate options as Apple does not seem to provide a good way of knowing whether they use internal or external TMDS for DVI.

Only valid on PowerPC. On Linux, the driver will attempt to detect the MacModel automatically. Option "TVStandard" "string" Used to specify the default TV standard if you want to use something other than the bios default. Valid options are: ntsc.
