Nella giornata di oggi Nvidia ha rilasciato la nuova versione del suo driver per sistemi operativi GNU/Linux.
Si tratta della versione 177.80 disponibile per il download nel sito ufficiale.
Forse per farsi perdonare del ritardo (in passato quasi come un’orologio svizzero il driver veniva rilasciato a distanza di 1 mese dalla versione precedente) la lista di miglioramenti e modifiche è abbastanza nutrito.
All’interno di essa sicuramente spicca il supporto alle nuoveGPUs (GeForce GTX 260, GeForce GTX 280, GeForce 9800 GTX+, GeForce 9800 GT, GeForce 9700M GTS, GeForce 9500 GT, mGeForce 8100P, nForce 780a, SLI mnForce 750a SLI, Quadro FX 770M, Quadro NVS 160M e Quadro NVS 150M).
Riporto quello che è il changelog completo (in lingua inglese: in italiano non è ancora disponibile):
- 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 1024×768 @ 60Hz and 800×600 @ 60Hz are allowed, rather than just 640×480 @ 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.
