Не знаю правильно ли назвал тему, но вообщем проблема в следующем - есть монитор Samsung 971P, кнопок, управляющих положением экрана на нем нет, в утилитах nvidia для винды это можно сделать программно, в nvidia-settings подобной настройки не нашел, подскажите пожалуйста как избавится от черной полосы справа, очень мешает

xorg.conf (н заню нужен ли)
