Дискретная видеокарта курит в сторонке. Как её припахать на всю систему? [Решено]

Обзавёлся техникой Acer Aspire V3-571G.

Core i3-3120m (2.5 GHz, 3 MB L3 cache).
nVidia GeForce GT730M with 2 GB Dedicated VRAM.
4 GB DDR3 Memory (добавил ещё 8, теперь 12, могу даже 16).

Радует 15.6" IPS Full HD экран. Кубунта смотрится гладенько, и нет чувства что "экран маловат".

Драйверы на видеокарту поставил:
sudo apt-get install nvidia-current

Эффекты отвалились...

Ещё поставил, сам туго понимаю что:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia primus

Эффекты заработали...

Драйвера:
2 открытых
1 проприетарный

Процессор пашет, видеокарта - курит. Как заставить её работать?

У винды есть nVidia Optimus, и видяха заводится, когда я запускаю всякие GTA4.

Есть команда, чтобы запускать видеокарту для отдельной программы, типа "нВидиаОптимус рукопашно" :))
optirun wine '/игра/игра.exe'

Хочу заставить карточку трудиться над всей системой
2 GB быстрой видеопамяти должны работать.

По старенькому нэтпуку знаю, что там видяха сопит на 133 MHz, но руками выжимается до 400 (если забить на температуру).
У больших ноутов интегрированные видеокарточки не ушли далеко от нетпучных.

Думал, гуглил, предпринял:
sudo killall kwin //убил kwin
sudo optirun kwin //запустил kwin на дискретной

Получил провал на старте компиза...
