Professional Displays). These cards have higher fidelity than standard DVI-driven or VGA-drivenmonitors that support 24-bit, 8-bit-per-channel signals.Work to support 30-bit visuals on the enterprise desktop is ongoing with X.org X servers at X11 R7.4 orlater. (To correctly manage mixed 30-bit and 24-bit visual requests, these servers require later versionsof GDM , Gnome, and KDE display managers). For more information on these advanced settings, seethe documentation provided with the drivers and the Linux distribution.AMD® / ATI graphics workstationsATI™ provides a command line tool to automatically configure the Xorg configuration file /etc/X11/xorg.conf. The aticonfig tool should be used immediately after the ATI graphics driver is installed toperform the initial configuration of the xorg.conf file.NOTE: The ATI graphics driver will not become functional until the following command is issued: # aticonfig --initialHP recommends the interactive configuration utilities provided by ATI. These utilities provide access to:● 3D Performance Management● X Server Display Information and Management- including screen layouts, display resolutions andtimings, multi-display settings and Xinerama.● X Screen # - including color gamma correction, XVideo settings, and Antialiasing requirements● GPU # - including vbios version, clock speed, driver, and probed monitor informationConfiguration changes can be previewed and saved by clicking “Apply” in the utilty interface.Additional documentation in html format is installed in the /usr/share/doc/ati directory.In addition to the Catalyst Control Center application, some of the features that can be configured usingthe aticonfig application include:● Xinerama— the X.org/XFree86 extension that supports continuous display technology on the Xserver. When enabled, it changes independent displays to continuous displays. Xinerama isconfigured with a ServerFlags option or enabled with a command-line option.NOTE: Xinerama only supports accelerated 3D between screens controlled by independentcards with the most recent Nvidia drivers (not ATI drivers). The NVIDIA-settings applet tool supportsinteractive configuration of this and other layout-specific features for the X server.● ATI Big Desktop–an ATI-specific driver configuration mode that supports Xinerama-likefunctionality across the two video ports of an ATI graphics card. When configured, it allows the Xserver to manage dual video ports as one independent display. User windows can traverse theentire graphics card framebufferNOTE: This mode is configurable only with the aticonfig configuration tool provided by ATI.● ATI Overdrive—enables you to change core or memory clock values.ENWW AMD® / ATI graphics workstations 15 PreviousNext |
