I have a notebook (ASUS N43) with a geforce GT435M graphics card. This card has the optimus technology. The notebook has a blue/white indicator which shows when the geforce is active or inactive, respectively.
On windows it works perfectly, blue/off when idle, white/on when using Firefox for example. On the other hand, when using ubuntu (10.10, but upgrading to 11.04) it is always on even when I'm doing nothing. I suppose this is a problem related with linux's drivers right?
- Should I download and install nvidia driver from their website or stick with the one ubuntu comes with? Could the nvidia's driver solve the optimus problem?
- Is there any simple way to get optimus working on ubuntu/linux? I saw some websites with some projects (bumblebee) developing some drivers... does it work? Is it stable?
[UPDATE:] I followed
@avilella's instructions and everything went well I guess. But the led continues to be always white meaning that the graphic is always on. Your example of google-chrome didn't work. The OpenGl gave me this results:
$ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 299 frames in 5.0 seconds = 59.631 FPS $ optirun glxgears * Starting Bumblebee X server bumblebee /usr/local/bin/bumblebee-enablecard: 1: ��: not found [ OK ] 1445 frames in 5.0 seconds = 288.877 FPS
What does it mean? What is that optirun? What improvements should I notice? So... my problem still subsists.
