    UPD:

    проблемы со странными тормозами были вызваны использованием непонятного clocksource. В связи с отсутствием “hpet” (видимо баги в BIOS не дают работать ACPI) пришлось ограничиться “tsc” добавив к параметрам ядра clocksource=tsc

    Вот скорее всего причина, по которой Xorg не заводится иногда:

    теперь осталось понять откуда этот timeout в DRM. При перезапуске иксов всё работает, а если грузиться из BIOS boot menu то этот timeout никогда не возникает.
    Похоже что вот Bugzilla подходящая: https://bugzilla.kernel.org/show_bug.cgi?id=68451

    Продолжаем докапываться до причины проблем. Теперь насчёт двойных кликов при касании. Похоже что в xorg приходит двойное нажатие от драйвера при кратком одиночном касании экрана:

    ^C

    сам драйвер при этом очень мелкий:

    Надеюсь удастся методом тыка побороть эту проблему.
