Bug 1398891

I see the same when running solaar using sudo. But that shouldn't be necessary. Can you not run it as yourself? That seems to work for me on F25.

Incidentally, the Python errors are benign as far as I can tell so these messages:

> /usr/lib/python2.7/site-packages/solaar/gtk.py:34: PyGIWarning: Gtk was
> imported without specifying a version first. Use gi.require_version('Gtk',
> '3.0') before import to ensure that the right version gets loaded.
>   __import__(module)
> /usr/lib/python2.7/site-packages/solaar/ui/notify.py:33: PyGIWarning: Notify
> was imported without specifying a version first. Use
> gi.require_version('Notify', '0.7') before import to ensure that the right
> version gets loaded.
>   from gi.repository import Notify

don't matter whereas these:

> No protocol specified
> Unable to init server: Could not connect: Connection refused
> No protocol specified
> Unable to init server: Could not connect: Connection refused
> [...]
> No protocol specified
> Unable to init server: Could not connect: Connection refused
> 
> (solaar:2534): Gtk-WARNING **: cannot open display: :0

do indicate a problem.

I don't think the problem you are having is due to Wayland. I am using Wayland, and solaar works fine.

I think this is something to do with the theme you have set. What desktop environment (GNOME 3? KDE?) and theme are you using?

Can you do the following in a Python shell:

  >>> from solaar.ui import icons
  >>> icons._init_icon_paths()
  >>> icons._default_theme.get_search_path()
  >>> icons._default_theme.has_icon("solaar")

Those last two lines should produce some output - please paste it here. Thanks!

Default F25 GNOME3

just installed latest updates - solaar is back to normal

Thanks for the update! This:

    >>> icons._default_theme.has_icon("solaar")
    False

would have been a problem, but it sounds like it's OK again now after updates.
