- Support for 24-bit pixel depth;
- RandR support up to version 1.4;
- 3D acceleration;
- Option "SWcursor" "boolean"
- Selects software cursor. The default is off.
- Option "Accel" "boolean"
- Enables or disables all hardware acceleration.
- Option "ZaphodHeads" "string"
- Specify the RandR output(s) to use with zaphod mode for a
particular driver instance. If you use this option you must use this
option for all instances of the driver.
- Option "DRI" "integer"
- Define the maximum level of DRI to enable. Valid values are 2 for DRI2 or 3 for DRI3. The default is 3 for DRI3 if the Xorg version is >= 1.18.3, otherwise 2 for DRI2.
- Option "EnablePageFlip" "boolean"
- Enable DRI2 page flipping. The default is on.
- Option "TearFree" "boolean"
- Set the default value of the per-output 'TearFree' property, which controls tearing prevention using the hardware page flipping mechanism. TearFree is on for any CRTC associated with one or more outputs with TearFree on. Two separate scanout buffers need to be allocated for each CRTC with TearFree on. If this option is set, the default value of the property is 'on' or 'off' accordingly. If this option isn't set, the default value of the property is auto, which means that TearFree is on for outputs with rotation or other RandR transforms, and for RandR 1.4 slave outputs, otherwise off.
- Option "AccelMethod" "string"
- Setting this option to none disables use of the
glamor acceleration architecture. In that case, all 2D rendering is done
by the CPU, but 3D and video hardware acceleration can still work. This is
mainly useful for OpenGL driver bring-up.
- Option "ShadowPrimary" "boolean"
- This option enables a so-called "shadow primary"
buffer for fast CPU access to pixel data, and separate scanout buffers for
each display controller (CRTC). This may improve performance for some 2D
workloads, potentially at the expense of other (e.g. 3D, video) workloads.
Note in particular that enabling this option currently disables page
flipping. The default is off.
