The easiest way is to use the command: If graphic performance such as playing videos is terrible, then make sure KMS Color Tiling is enabled. Enables or disables all hardware acceleration. After this and all older R Radeon cards were discontinued, the R series was subsequently known as the Radeon , in keeping with ATI’s new naming scheme. This option allows us to override the heuristic. Valid values are 16 and

The default is EXA.

This can help reduce heat and increase battery life by reducing power usage at the expense of performance. Option “DefaultConnectorTable” ” boolean “. Partners Support Community Ubuntu. If you think quality is not optimal when playing back HD video with horizontal resolution larger than this settingincrease this value.
After these changes, you may use as many monitors as possible without an increased power consumption of your system.
Note With more than one monitor connected, the memory clock will NOT be on full speed as it was before. Check the version of Ubuntu you have installed: Enables or disables the use of 6 bits per color component when in 8 bpp mode emulates VGA mode. The fglrx drivers only work with certain versions of the X server. Precision in bits per pixel of the shared depth buffer used libux 3D acceleration.
A compatible HDCP display is also needed for this. There are various practical technical reasons for this.
AMD/ATI Open Source Drivers (amdgpu, radeon, r128, mach64)
Microcode firmware is required for R and newer GPUs. The default value is 0x1E.
See the radeon 4 manual page and the radeon page on the X wiki for more information. Note R6xx and newer radeons have an internal thermal sensor that is exposed by the driver on most cards that utilize it.
In some cases it appears the ‘auto’ settings don’t work correctly, so make sure to explicitly enable the integrated rv010. The silicon just can’t do what is required lknux support 1. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
Xorg 1xorg. Option “ForceLowPowerMode” ” boolean “. Option “ColorTiling2D” ” boolean “.
This is not an exhaustive list. However, savedconfig editing is entirely optional, those in a hurry may not want to take this route. The default is to enable hardware acceleration. Pageflipping is supported on all radeon hardware.
The Radeon’s Ark demo presents a science-fiction environment with heavy use of features such as multiple texture layers for image effects and detail. Note “dpm” is the default power management method since kernel 3.
I’d rather stick with more main-stream sources. Subpixel order is used for subpixel decimation on flat panels. Make sure your OpenGL renderer string does not say “software rasterizer” or “llvmpipe” because that would mean you have no 3D hardware acceleration: I’m currently using the fglrx driver ATI proprietary driver.
