Posted on: 10/08/2008 10:45 AM

New nVidia Linux Display Drivers are now available

Release Highlights

Added support for the following new GPUs:
GeForce GTX 260
GeForce GTX 280
GeForce 9800 GTX+
GeForce 9800 GT
GeForce 9700M GTS
GeForce 9500 GT
GeForce 8100P
nForce 780a SLI
nForce 750a SLI
Quadro FX 770M
Quadro NVS 160M
Quadro NVS 150M
Improved support for RENDER masks, as well as RENDER repeating modes and transformations, for video memory pixmaps.
Added accelerated support for RENDER convolution filters for video memory pixmaps on GeForce 8, 9 and GTX GPUs.
Improved support for RENDER operations with the same source and destination; this should performance in some situations, e.g. when dragging Plasma applets in KDE4.
Improved GPU video memory management coordination between the NVIDIA X driver and OpenGL implementation; this should improve performance with e.g. the KDE4 OpenGL compositing manager.
Added an 'AllowSHMPixmaps' X configuration option, which can be used to prevent applications from using shared memory pixmaps; the latter may cause some optimizations in the NVIDIA X driver to be disabled.
Fixed a text rendering performance regression that affected GeForce 6 and 7 series GPUs.
Fixed a regression that caused the 'Auto' SLI X option setting to not enable SLI.
Fixed a bug that caused system hangs when using the NV-CONTROL interface to change GPU clock frequencies.
Added support for DisplayPort display devices (including 30-bit devices).
Resolved various stability problems on GeForce 8, 9 and GTX GPUs, as well as some GeForce 6 and 7 PCI-E GPUs.
Fixed a bug that resulted in GPU errors when changing the TwinView display configuration while using Compiz.
Further improved the error recovery paths taken in case of GPU command stream corruption.
Updated mode validation, in cases when no EDID is detected, such that 1024x768 @ 60Hz and 800x600 @ 60Hz are allowed, rather than just 640x480 @ 60Hz.
Removed an old workaround that caused incorrect Xinerama information to be reported after enabling a second TwinView display.
Fixed corruption when using SLI in SFR mode with OpenGL-based composite managers.
Fixed the subpicture component order reported by the NVIDIA X driver's XvMC implementation.
Added a workaround for broken EDIDs provided by some Acer AL1512 monitors.
Fixed a bug that caused GLXBadDrawable errors to be generated when running more than one OpenGL application with anti-aliasing enabled on GeForce 6 and 7 GPUs, e.g. wine.
Fixed a problem that could result in IRQs being disabled on some multi-GPU SMP configurations.
Worked around cache flushing problems (on some Linux kernels) that caused corruption and stability problems.
Added experimental support for PCI-E MSI.
Fixed a bug that resulted in AGP FW/SBA settings and overrides being applied incorrectly when using the Linux kernel's AGP GART driver.
Improved compatibility with recent Linux 2.6 kernels.
Updated the X driver to consider /sys/class/power_supply when determining the AC power state.
