nouveau драйвер предотвращает приостановку, и мне он даже не понадобится

У меня есть Dell XPS 15, со встроенным графическим процессором Intel и дискретным графическим процессором Nvidia. Я использую программу Nvidia X Server Settings, чтобы настроить мою систему на использование Intel в целях экономии энергии. Тем не менее, драйвер nouveau загружен, и когда это так, в большинстве случаев, когда я пытаюсь приостановить, приостановка терпит неудачу, и я просто оказываюсь на экране блокировки (и могу нормально разблокировать). Однако однажды в синюю луну это работает.

Теперь я был бы доволен решением, которое заставляет драйверы Nouveau работать с приостановкой, но я также был бы в порядке, если бы вообще не загружал их, поскольку я все равно использую Intel GPU.

Я использую 18.04 и ядро ​​4.15.0-20.

Если использовать настройки сервера Nvidia X для переключения на проприетарные драйверы nvidia, указанные выше изменения отражают это, и приостановка работает нормально. (На самом деле это неправда, но он ломается другим, менее радикальным образом, и мне все равно.)

У меня есть несколько файлов в /etc/modprobe.d/ (я этого не делал. не создаю), что, я думаю, внесет в черный список модерна. Вывод cat /etc/modprobe.d/nvidia-graphics-drivers.conf /etc/modprobe.d/blacklist-nvidia.conf :

То же / var / log / syslog включает аналогичные жалобы на nouveau 0000: 01: 00.0: timeout и все это при каждой загрузке. В тех редких случаях, когда приостановка проходит успешно, в журнале отсутствует вся эта чушь о модернизме.

Есть какие-нибудь указания, как решить проблему (отлично) или отключить модерн (хорошо)? Почему файлы черного списка /etc/modprobe.d/ не предотвращают загрузку всего драйвера? Как мне вручную выгрузить его? (Я пробовал modprobe -r без особого успеха.)
