    58You may also consider using the [/wiki/CSC/OpenCL OpenCL CSC] module, which can also use the GPU and is more generic (not vendor specific), better tested and often [/wiki/CSC/Performance faster].

    9 == {{{csc_nvcuda}}} Installation ==
    10 * you need to build xpra with the flag "{{{--with-csc_nvcuda}}}", since this module is not enabled by default.
    11 * you must use a sufficiently recent version of the {{{nvidia}}} video drivers, preferably obtained directly from nvidia, and not the {{{nouveau}}} drivers (which you should probably remove).
    12 * the build file relies on the presence of a standard {{{pkgconfig}}} file to find the CUDA libraries and headers. nvidia does not provide one with the SDK, so you will need to create one. You can use this example [/attachment/wiki/CSC/NVCUDA/cuda.pc cuda.pc] as a template.
