Remote OS: Ubuntu 16.04 Local OS: Mac OSX High Sierra 10.13.6
I am starting an HTML5 xpra server with this command:
xpra start --bind-tcp=0.0.0.0:9876 --html=on --start-child=xterm --mdns=no
Everything works and I can access it locally on firefox, chrome, and safari browsers. Unfortunately, the "start" menu in the system tray doesnt show any items to select and the system log is showing that it cannot find the application menu.
^ Warning: cannot use application menu data:^[[0m ^ no python-xdg module^
I know this is very similar to #2174, but I looked and the version I am using includes the fix made at changeset r21880. So I am not certain what would be causing it. "xpra attach -d tray" results in the following:
__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) xpra initialization error: cannot access the default display ''
Which version and package do you have installed?
You can try to run the menu code by hand, see ticket:2174#comment:10.
(you may need to run
locate xdg_helper.py to find it first)
xpra initialization error: cannot access the default display ''
This has nothing to do with the problems above. The terminal you are starting from does not have a
$DISPLAY value set, for whatever reason. (maybe you unset it, logged in via ssh, etc)
Xpra needs a display to show its windows!
It's not at all clear what you're trying to do.
xpra attach is for running the client locally, but you said you were using the html5 client.
BTW: do NOT use PDF for text files. Use test files. (system log)
Ok Sorry I read about the "xpra attach -d tray" method from another comment but you're right that makes no sense since I'm logging in via ssh.
I'm using version 3.0.5-r24939-1 which I found in the winswitch instructions linked to on the downloads page.
I foundboth a python 2.7 and 3 version of xdg_helper. I ran the xdg_helper.py file in python2 and received:
Warning: cannot use application menu data: 2020-01-23 03:09:27,189 no python-xdg module no menu data found
then i ran the python3 version and got:
Traceback (most recent call last): File "/usr/lib/python3/dist-packages/xpra/platform/xposix/xdg_helper.py", line 312, in <module> r = main() File "/usr/lib/python3/dist-packages/xpra/platform/xposix/xdg_helper.py", line 304, in main menu = load_xdg_menu_data() File "/usr/lib/python3/dist-packages/xpra/platform/xposix/xdg_helper.py", line 237, in load_xdg_menu_data xdg_menu_data = do_load_xdg_menu_data() File "/usr/lib/python3/dist-packages/xpra/platform/xposix/xdg_helper.py", line 242, in do_load_xdg_menu_data from xdg.Menu import parse, Menu, ParsingError File "/usr/local/lib/python3.5/dist-packages/xdg/__init__.py", line 120 XDG_RUNTIME_DIR: Optional[Path] = Path(os.environ["XDG_RUNTIME_DIR"]) ^ SyntaxError: invalid syntax
python2 and received:
no python-xdg module
File "/usr/local/lib/python3.5/dist-packages/xdg/__init__.py", line 120
That's not a system file from a package, you must have installed that yourself.
XDG_RUNTIME_DIR: Optional[Path] = Path(os.environ["XDG_RUNTIME_DIR"])
SyntaxError: invalid syntax
And there's the problem.
Remove this stuff you've installed and use the system provided
python3-xdg package instead.
Not heard back, closing.
