Nvidia rilascia i Driver 337.12 Beta per Linux con supporto all'overclock

10 Aprile 2014 1


Nvidia ha rilasciato un nuovo pacchetto driver per Linux, parliamo più precisamente della versione Beta 337.12 che oltre a correggere come di consueto alcuni importanti bug, aggiunge il supporto alle nuove schede grafiche sella serie GTX 800M e, non per ultima, la possibilità di effettuare overclock o downclock dei chip GeForce.

Tra i problemi risolti segnaliamo quello relativo al bug su OpenGL che causava in alcune occasioni il blocco del sistema, e diverse ottimizzazioni per quanto riguarda l'interfaccia Display Port 1.2.

Tornando alle schede video, la release 337.12 supporta i seguenti chip:

GeForce 830M
GeForce 840M
GeForce 845M
GeForce GTX 850M
GeForce GTX 860M
GeForce GTX 870M
GeForce GTX 880M
GeForce GT 705
GeForce GT 720

A questo link per il download mentre a seguire le note di releaswe complete:

    • Fixed a bug that could cause OpenGL programs to freeze under some low memory conditions.
    • Updated the display configuration page in nvidia-settings to uniquely identify DisplayPort 1.2 monitors by displaying the monitor GUIDs.
    • Fixed a bug that could cause ECC settings to be displayed incorrectly in nvidia-settings when changing ECC settings on a multi-GPU system.
    • Removed the "OnDemandVBlankInterrupts" X configuration option: this option has been enabled by default since version 177.68 of the NVIDIA Unix driver, and the documentation had not been updated to reflect the new default value.
    • Fixed a bug that caused GPU errors when hotplugging daisy-chained DisplayPort 1.2 displays.
    • Updated the color correction settings page in the nvidia-settings control panel to reflect gamma changes made by other RandR clients while the control panel was already running.
    • Fixed a bug that prevented the use of multiple simultaneous X servers on UEFI systems.
    • Updated the nvidia-settings source package to build libXNVCtrl when building nvidia-settings, instead of relying on a pre-built library.
    • Added the ability to over- and under-clock certain GeForce GPUs in the GeForce GTX 400 series and later.  For GPUs that allow it, an offset can be applied to clock values in some clock domains of some performance levels.  This clock manipulation is done at the user's own risk.  See the README documentation of the "CoolBits" X configuration option for more details.
    • Updated the minimum required version of GTK+ from 2.2 to 2.4 for nvidia-settings.
    • Renamed the RandR output property _GUID to GUID now that it is an official property documented in randrproto.txt:http://cgit.freedesktop.org/xorg/proto/randrproto/commit/?id=19fc4c5a72eb9919d720ad66734029d9f8e313b1
    • Reduced CPU utilization and GPU memory utilization of the NVIDIA EGL driver.
    • Added support for the following EGL extensions:
        - EGL_EXT_buffer_age;
        - EGL_EXT_client_extensions;
        - EGL_EXT_platform_base;
        - EGL_EXT_platform_x11.
  • Renamed the "Clone" setting of the "MetaModeOrientation" X configuration option to "SamePositionAs", to make clear that this setting applies to the position only, and not to the resolution of modes in the MetaMode.
  • Added NV-CONTROL attribute NV_CTRL_VIDEO_ENCODER_UTILIZATION to query utilization percentage of the video encoder engine.
  • Added support for the GLX_NV_delay_before_swap extension.  For more details, see the extension specification:http://www.opengl.org/registry/specs/NV/glx_delay_before_swap.txt
  • Report correct buffer sizes for RGB GLX visuals, GLXFBConfigs, and EGLConfigs.  Previously, RGB10 and RGB8 formats were reported as having 32 bits, and RGB5 formats were reported as having 16 bits.  Now they are correctly reported as 30, 24, and 15 bit formats respectively as required by the GLX and EGL specifications.
