дискретный графический процессор не работает после обновления

4

Я обновил Ubuntu несколько дней назад, и мой дискретный GPU перестает работать. Когда я запускаю ноутбук, я получаю некоторые ошибки, начиная с

unable to handle kernel paging request at ...some gibberish(probably some kind of adress)..

Мне нужно указать Ctrl+Alt+F7 (или, возможно, F8 не помню), чтобы перейти на экран регистрации, где я продолжаю вести журнал. Все швы работают нормально, за исключением случаев, когда я пытаюсь запустить что-то с дискретным графическим процессором. Я получаю сообщение об ошибке:

[24723.313790] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card

[24723.313819] [ERROR]Aborting because fallback start is disabled.

Я не знаю, что пошло не так.

Недавно я удалил binutils-gold, потому что у меня были проблемы с компилятором haskell ghc.

И вот журнал aptitude для этого обновления, после которого GPU сломался:
