Nvidia Optimus and Bumblebee

I have been using Bumblebee on my Dell Vostro 3750 for about 6 weeks now and have found it reliable and performant.  My only niggles are the following:

1.) The need to run or configure optirun prior to the graphics card being initialised.  It would be nice if Bumblebee could detect an application making a 3d call and enabling the card automatically.

2.) The fact that my display would cut out whenever Ubuntu 12.04.1 started up.  This was recently resolved by discovering that acpi=off fixed the issue which led me to find the following post:

https://github.com/Bumblebee-Project/Bumblebee/issues/255

This led to

https://bugzilla.redhat.com/show_bug.cgi?id=734041

and finally

https://wiki.archlinux.org/index.php/Backlight#ACPI

I updated /etc/default/grub with the following GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"
and ran sudo update-grub.  My machine is now working perfectly.  Yay.


Bumblebee is an incredibly promising development and I am proud of the work that the team has done.  3 cheers for open source developers and their hard work !

  2. Hello,

    Thanky for your post. I have the same Dell Vostro 3750 with Ubuntu 12.04 installed. Everything works fine, but there is a high frequency noise every time when I move the mouse or playing a video. In the battery mode there is no noise. With Windows 7 there is no noise in the normal mode with AC power supply or in the battery mode. Do you have any idea's howto fix this issue?

    Greetings

    Peter
