However, this has been demonstrate to be buggy on older hardware and , but ok on PineView and later so on those chipsets defaults to off. Enabled Option “AccelMethod” ” string ” Select acceleration method. This option allows to pass the path to load an EDID from per output. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. Option “Tiling” ” boolean ” This option controls whether memory buffers for Pixmaps are allocated in tiled mode. Some portions of the panel may be unused if the aspect ratio of the selected mode does not match that of the panel.

January 29th, 1. Did you have to do any thing else to apply the new drivers? The effect of such missed swaps is the output jitters between 60fps and 30fps, and in the worst case appears frame-locked to 30fps.

Each output listed below may have one or more properties associated with it like a binary EDID block if one infel found. Option “HotPlug” ” boolean ” This option controls whether the driver automatically notifies applications when monitors are connected or disconnected. For example, see these: A tiled framebuffer is required for power conservation features, but for certain system configurations you may wish to override this and force a linear layout.

Note that this replicates what the compositing manager should be doing, however TearFree will redirect the compositor updates and those ubunut fullscreen games directly on to the scanout thus incurring no additional overhead in the composited case.


CRTC can be manually assigned to individual heads by preceding the output names with a comma delimited list of pipe numbers followed by a colon. Sometimes the automatically selected backlight interface may not correspond to the correct, or simply most useful, interface available on the system. If enabled, the calls will avoid tearing by making sure the display scanline is outside of the area to be copied before the copy occurs. Also note that not all compositing managers prevent tearing, and if the outputs are rotated, there will still be tearing without TearFree enabled.

This is the only mode which guarantees that every pixel of the panel will be used. Full aspect Scale the image as much as possible while preserving aspect ratio. Throttling ensures that the GPU does not lag too far behind the CPU and thus noticeable delays in user responsible at the cost of throughput performance.

If you set this option you must use it with all instances of the driver. Lid status support added by Alan Hourihane. It is a Boolean attribute with values of 0 never sync or 1 always sync. Option “Accel” ” boolean ” Enable or disable acceleration.

Thanks for the answer.

These outputs cannot be assigned to the regular displays attached to the GPU, but do otherwise act as any other xrandr output and share a portion inhel the regular framebuffer.

I snagged a few old laptops we were throwing out at work.

I didn’t have any problems whatsoever, but it’s an “ultra-portable”, so you would expect it to have some performance limitations, but it was a whole lot snappier than with Win XP especially for boot and shut down times. Some portions of the panel may be unused if the aspect ratio of the selected mode does not match that of the panel.

Intel Corporation HD Graphics [ VideoRam integer This option specifies the amount of system memory to use for graphics, in KB. If a chip supports more outputs than it has CRTCs say local flat panel, VGA and TV in the case of many outputstwo of the outputs will have to be “cloned”, meaning that they display the same framebuffer contents or one displays a subset of another’s framebuffer if the modes aren’t equal.

Home Questions Tags Users Unanswered. Enabled use hardware rotation Option “VSync” ” boolean ” This option controls the use of commands to synchronise rendering with the vertical refresh of the display.

I have Ubuntu Details on bug reporting can be found at https: What should I do? When the X server starts, we then take the list of connected displays and framebuffer layout and use that for the initial configuration. Until that process is complete, the ability to choose which backend to use remains for backwards compatibility.

For example, see these:.
