Hi there, I tried to get AW to run on my Ubuntu 18.04 (Macbook Pro hardware), but I got this error repeatedly:
2018-10-08 15:21:53 [ERROR]: Exception thrown while trying to get active window: Can't connect to display ":0": b'No protocol specified\n' (aw_watcher_window.main:68) Traceback (most recent call last): File "aw_watcher_window/main.py", line 65, in heartbeat_loop File "aw_watcher_window/lib.py", line 44, in get_current_window File "aw_watcher_window/lib.py", line 6, in get_current_window_linux File "<frozen importlib._bootstrap>", line 968, in _find_and_load File "<frozen importlib._bootstrap>", line 957, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 673, in _load_unlocked File "/home/travis/virtualenv/python3.5.6/lib/python3.5/site-packages/PyInstaller/loader/pyimod03_importers.py", line 631, in exec_module File "aw_watcher_window/xlib.py", line 11, in <module> File "site-packages/Xlib/display.py", line 89, in __init__ File "site-packages/Xlib/display.py", line 71, in __init__ File "site-packages/Xlib/protocol/display.py", line 167, in __init__ Xlib.error.DisplayConnectionError: Can't connect to display ":0": b'No protocol specified\n'
…at a glance I would say it does not expect other monitors than the default one, but disconnecting them, changed nothing.
Some creative googling led me to this post ( TLDR; there is a bug in python-xlib ), that offered the workaround:
$ xhost +
So is this something that can be fixed in a more structured way by some creative additions to the AW config files?
