Installing Xpra 1.0 without root permissions is not possible the way it is mentioned on wiki/Building using --home=<instdir>.

Possible fix: Only run setup.py line 1985-1994 if argument --home= is not set.

P.S: Thanks for the great Xpra!

Hello,

on MacOSX Xpra-GUI does not show up, if Xpra was installed by a user and not by an admin. Even though, Xpra does not fail to start completely, but it only runs in the background and uses CPU time.

What part of Xpra makes it necessary to install Xpra from an admin account? Is there a chance to allow Xpra to be installed to a MacOSX system by a standard user? If not, is it possible to show an error message, if Xpra is missing some privileges and cannot start?

Best, Jens Henrik

Hello,

Xpra currently fails for NVENC versions which have a minor number != 0.

In xpra/codecs/nvenc7 the following code checks the version of the NVENC API in init_module() (line 2531):

    if NVENCAPI_VERSION!=0x7:
        raise Exception("unsupported version of NVENC: %#x" % NVENCAPI_VERSION)

NVENCAPI_VERION comes from header file Samples/common/inc/nvEncodeAPI.h of NVIDIAs NVENC SDK. It is defined here like this (line 113):

    #define NVENCAPI_VERSION (NVENCAPI_MAJOR_VERSION | (NVENCAPI_MINOR_VERSION << 24))''

This means that NVENCAPI_VERSION looks like this:

    0x0000007 == 0x7 for 7.0
    0x1000007 != 0x7 for 7.1

=> if NVENCAPI_VERSION!=0x7: fails for version 7.1

nvEncodeAPI.h also defines 
    #define NVENCAPI_MAJOR_VERSION 7

A possible fix could be:

    if NVENCAPI_MAJOR_VERSION != 7:
        raise Exception("unsupported version of NVENC: %#x" % NVENCAPI_MAJOR_VERSION)
