Ни у кого нет идей, куда копать, чтобы решить весь этот букет проблем?

Проблема решилась незамысловато. Поменял кабели местами на видеокарте.
Как понятно из заголовка темы, есть два монитора - основной и дополнительный. Проблема с вертикальной синхронизацией
В nvidia-settings включаем “Sync to VBlank” и выбираем нужный нам монитор, где Vsync будет работать. Но это касается только xvideo. В самой среде же всё наоборот - на основной мониторе вертикальная синхронизация не работает, наблюдаю разрывы окон при их перетаскивании, а на дополнительном все замечательно.
Как сделать наоборот?

Решил не создавать отдельную тему, отпишусь здесь.
Не работает спящий режим на ноуте - при попытке выйти из него тупо черный экран. Мигающий курсор на пару секунд при уходе в сон есть. В логах ничего:

П.С. Разобрался, это таки wicd шалил. Остановка демона перед входом в сон и запуск после выхода решили проблему.
