nvidia-graphics-drivers-195 (195.22-0ubuntu0~sevenmachines2) lucid; urgency=low
* debian/changelog: add nvidia release notes
Release highlights:
* Enhanced the VDPAU blit-based presentation queue to provide values of
"first_presentation_time" that have less jitter.
* Add support for R16F and RG32F GLXFBConfigs when using GeForce 8 series
and higher GPUs.
* Added support for NVIDIA 3D Vision Stereo on Linux with Quadro GPUs.
See the "Stereo" X configuration documentation in the README for details.
* Added support for A2BGR10 32-bit GLX visuals on 30-bit X screens. These
allow some level of window transparency when using 30-bit visuals with GLX
and Composite, but they may cause problems with older X servers and/or
applications. ARGB GLX visuals can be disabled by adding:
Option "AddARGBGLXVisuals" "False"
to the X configuration file.
* Fixed a problem that caused DisplayPort devices to behave incorrectly when
DPMS power saving mode was triggered.
* Updated VDPAU to improve thread concurrency. See the README for details.
* Altered NVIDIA X driver behavior in the case that no display devices are
connected to the GPU. Previously, in this case, the NVIDIA X driver would
pretend a CRT was connected to the GPU. Now, the NVIDIA X driver will not
automatically pretend that any CRTs are connected. If the X driver does not
detect any connected display devices, the X server will fail to start.
To restore the old behavior, use the ConnectedMonitor X configuration
option; e.g.,
Option "ConnectedMonitor" "CRT"
Alternatively, if display is not desired, Quadro and Tesla GPU users can
enable "NoScanout" mode, which bypasses any mode timing validation or use
of display devices; this is configured with:
Option "UseDisplayDevice" "none"
* Disabled software cursors when the driver is operating in "no scanout"
(UseDisplayDevice "none") mode. The software cursor image is not visible
in remote desktop applications or screenshots anyway, so having software
cursor enabled was unnecessary.
* Changed glXSwapBuffers() behavior for a pixmap such that it is now a no-op
in the direct rendering case in order to match the indirect case and
comply with the GLX spec. Previously, calling glXSwapBuffers() on pixmaps
in the direct case would swap the pixmap's buffers if the pixmap was
double buffered.
* Modified the installation location and names of internal VDPAU libraries
to conform to conventions and Debian packaging guidelines. New versions of
libvdpau expect this layout. Compatibility with old versions of libvdpau is
maintained with symlinks.
* Fixed a bug that could cause errors in graphical applications run after a
previous application using VDPAU and OpenGL. This behaviour was observed
when running Gwenole Beauchesne's hwdecode-demos application.
* Modified vdpau.h to increment VDPAU_VERSION, to reflect the fact that new
features have been added in the past. Also, add the new define
VDPAU_INTERFACE_VERSION.
* Fixed a periodic temporary hang in the VDPAU blit-based presentation
queue.
* Fixed a problem that caused resolution limitations or corruption on
certain DisplayPort devices such as the Apple 24" Cinema display or some
DisplayPort to VGA adapters.
* Disabled the UseEvents option for GeForce 8 series and higher GPUs due to
a problem that causes occasional short hangs. It will be re-enabled when
that bug has been tracked down and fixed.
* VDPAU now allows multiple streams to be decoded at once, without the need
to set any environment variables.
