Невозможно использовать сочетание клавиш, включая Alt+Shift

Summary

Любая комбинация клавиш быстрого доступа, включающая Alt+Shift не принимается. Когда я пытаюсь установить (или использовать) сочетания клавиш быстрого доступа в PhpStorm, которые включают Alt+Shift, ничего не происходит. Я думал, что это влияет только на PhpStorm, но когда я пытаюсь установить эти ярлыки в моем терминале, клавиши тоже не работают. Я уже пытался удалить все комбинации клавиш Alt+Shift из системных ярлыков, которые я смог найти, но это тоже не помогло. Похоже, что это влияет на мою внешнюю клавиатуру только в том случае, если при использовании внутренней клавиатуры ноутбука она работает просто отлично. Поэтому я попробовал другую клавиатуру (CORSAIR STRAFE RGB MK.2 Mechanical Gaming Keyboard) и с этой клавиатурой она работает просто отлично.

Установка

Lenovo ThinkPad L490
Убунту 20.04.1 LTS GNOME Shell 3.36.4
Клавиатура: Sharkoon Skiller Pro

Мой ноутбук подключен к USB-C Triple-4K док-станции от Displaylink. Внешняя клавиатура подключена к USB-переключателю, который подключен к док-станции. Я пытался подключить клавиатуру непосредственно к док-станции и к ноутбуку, но это ничего не изменило.

Устройство захватывает

Так что мне кажется, что никакие системные ярлыки не могут заблокировать комбинацию, и я попытался выяснить, какая программа ловит комбинацию, основываясь на этом ответе :

$ KEY=shift+alt
$ xdotool keydown ${KEY}; xdotool key XF86LogGrabInfo; xdotool keyup ${KEY}

Дает мне

На [. ...] он сначала продолжает длинный список gabs, подобный тому, что вы видите, а затем просто перечисляет "Печать всех зарегистрированных захватов..." других запущенных программ, но у них нет никаких захватов. Мне интересно, почему он показывает только пассивные захваты и ни одного активного захвата.... Я пробовал это с разными комбинациями Alt+Shift типа Ctrl+Alt+Shift+N с тем же самым результатом.

Я пытался xev убедиться, что нажатия клавиш сняты и что клавиатура не сломана. Это вывод при нажатии Alt+Shift:

Все, что происходит между [ вырезано здесь ] и [конечный след], не происходит, когда я подключаю другую клавиатуру.

Дополнительная информация

Так как Quasímodo предложил в комментариях , это может быть вмешательством гномов, поэтому я установил icewm и попытался установить Alt+Shift для моего терминала, но безуспешно. Я действительно пытался использовать XF86LogGrabInfo, как описано выше, но с тем же результатом, все пассивные захваты (их опять много), где сделаны из оболочки icewm.

Как я могу выяснить, какие блоки Alt+Shift комбинации?
