Странные проблемы с индикатором Solaar

[Vladimyr]

Доброго времечка всем убунтоводам!
Прошу совета: может, кто сталкивался с подобным.
С некоторых пор перестал нормально работать индикатор Solaar,
пишет, что "устройства не обнаружены". Время от времени
(всё реже и реже), начинает работать нормально - показывает
и клавиатуру, и мышь, но чаще в упор их не видит.
(раньше "проблески сознания" были чаще, но с тех времён
много апдейдов утекло).
что показательно: запущенный из командной строки, ВСЕГДА
работает как надо.
где бы порыться, чтоб поискать причину? 
стоит ubuntu 16.04 64-bit + unity.

Выясните из какого файла происходит автоматический запуск.
Вероятнее всего нужно просто сделать запуск с задержкой на 5 - 10 секунд.

пробовал - не помогает.

в любом случае, если я запускаю его командой

Код: [Выделить]

solaar
(запускает индикатор в трее), он пишет, что "приёмник не найден".

а вот если

Код: [Выделить]

solaar show (выдаёт в консоль список устройств), то всё показывает как надо.

что-то я ступил... есть же режим дебага! вот вывод:
