 You must have [http://mathema.tician.de/software/pycuda/ PyCUDA] installed, and a recent enough version of the nvidia drivers.
-How you install those drivers is entirely up to you: [http://www.nvidia.com/object/unix.html nvidia installers], [http://negativo17.org/nvidia-driver/ negativo17 repository], [http://rpmfusion.org/ rpmfusion], [http://elrepo.org/tiki/tiki-index.php elrepo], etc..

 If your CUDA ({{{libcuda.so}}}) or NVENC ({{{libnvidia-encode.so}}}) libraries are installed in an unusual location, it is your responsibility to ensure they can be loaded at runtime, usually by adding the directory to the {{{LD_LIBRARY_PATH}}}.
 
-Note: xpra version 0.15 or newer is required. (older versions require the full CUDA SDK at runtime)

 == Building ==
-* Download the [https://developer.nvidia.com/cuda-downloads CUDA SDK] and install it. If present, you should remove any previously installed nvidia drivers: both "nouveau" and nvidia's proprietary drivers - either install the drivers bundled with CUDA or a sufficiently recent version, preferably directly from nvidia (ie: {{{331.20}}}, {{{331.49}}} and {{{334.21}}} are known to work with the version 3 SDK - {{{337.12}}} probably requires SDK version 4 or different keys, {{{331.79}}} also works but may require newer license keys, more information here: #595)
-* Download the [/attachment/wiki/Encodings/nvenc/cuda.pc cuda.pc] pkgconfig file (missing from the SDK) and install it (usually in {{{/usr/lib64/pkgconfig}}} for 64-bit systems)

 * [http://wiki.tiker.net/PyCuda/Installation/Linux Install PyCuda]
-* Download the latest [https://developer.nvidia.com/nvidia-video-codec-sdk NVENC SDK] (aka "NVIDIA VIDEO CODEC SDK") and install it (just unzip into {{{/usr/local/}}} - then create a symlink named just {{{nvenc}}})
-* Download the [/attachment/wiki/Encodings/nvenc/nvenc.pc nvenc.pc] pkgconfig file (also missing from the SDK) and install it
-* Build xpra version with nvenc support:
+* Download the [https://developer.nvidia.com/nvidia-video-codec-sdk NVENC SDK], aka "NVIDIA VIDEO CODEC SDK" and install it (just unzip into {{{/opt/}}}), then create a symlink named just {{{/opt/nvencV}}} (where V is the SDK version, ie: {{{nvenc4}}}). You may want to stick with SDK versions 3 or 4 if you plan on using consumer cards with a license key, as the SDK version 5 removes the ability to use keys (see #825).
+* Download the pkgconfig file matching your SDK version (ie: [/attachment/wiki/Encodings/nvenc/nvenc4.pc nvenc4.pc]) and install it (same location as the {{{cuda.pc}}})
+* When building xpra, nvenc support should be auto-detected, but you can try forcing it to verify, ie: for version 4:
 {{{
-./setup.py install --with-nvenc
+./setup.py install --with-nvenc4
 }}}
