Я установил и запустил Cygwin X Server, и все, кажется, работает. Войти из startxwin:
$ startxwin

Затем я подключаюсь к удаленному хосту Linux и экспортирую переменную отображения:
ssh -Y some_host
export DISPLAY=:0.0
Когда я пытаюсь запустить xclock кажется, что все работает (нет ошибки на удаленном хосте), но ничего не появляется локально:
$ xclock &
[1] 28392
Что может быть не так?
UPD оказалось, что xclock подключен к удаленному x-серверу, а не к моему локальному. Его окно было видно, когда я физически вошел на удаленный компьютер (не через ssh).
