NVIDIA Quadro NVS 140MThe NVIDIA Quadro NVS 140M is a mobile video card with a G86 core and either 128 MB or 256 MB graphics memory. Features
Linux X.Org driverDefault X.Org NVidia driver, called "nv" works. NVIDIA proprietary driverSupport for Quadro NVS 140M has been introduced in the NVIDIA Linux unified driver version 100.14.09 (released on 8 June 2007). For the latest drivers go to the NVIDIA Unix Drivers page. Note that NVIDIA proprietary drivers do not work with a Xen virtualized kernel. CUDASince it has a G86 core, NVidia CUDA works on this video card, even though it is not listed in the CUDA manuals. Running very large problems (like the SDK samples) however might fail because of running out of the small graphics memory. LCD Backlight Brightness Control on T61To the best of my knowledge, no one has been able to get LCD backlight brightness control to work with this video card on the T61 when using the proprietary driver. However, brightness control works fine when using the vesa driver, so it seems that the problem lies with the Nvidia driver itself. Strangely, if the nvidia module is loaded with the argument NVreg_EnableBrightnessControl=1, one can switch to a virtual console, change the lcd brightness level there, and have that level preserved after switching back to the X session. This was tested with the acpi video driver included in the vanilla Linux 2.6.21-6 kernel. |
