У меня ноутбук с видеочипами Nvidia и Intel
Гибридную графику настроил давно, игрушки запускались через optirun без проблем ! Последние пол года не пользовался Nvidia, но вчера решил поиграть.
При запуске команды optirun glxgear в dmesg следующие сообщения:

После перезагрузки ноутбука всё заработало. Может причина в том, что я стал пользоваться режимом ожидания вместо выключения ?
Или что у меня 4gb ОЗУ и часто память выгружается в подкачку, но я перед запуском игры закрыл все программы и выполнил swapoff/swapon .
