bumblebee project + libbsd

Postby Hellboy » 2012/02/20 11:13:24

I am doing some testing to see if my laptop MSI ge620 supports Centos 6.
Everything works out of the box, except for the videocard i have to install bumblebee, because it's a hybrid videocard. And the lifetime of my battery decreases to 1,5 hours instead of 5 with windows 7.

I looked at the following howto:
https://fedoraproject.org/wiki/Bumblebee

to see if i can get it to work, first problem was the autoconf version, which i changed in the makefile.
But then it wants libbsd, i have searched all yum repos, but i can't find it.

Who has any experience with bumblebee and centos 6 and can share his experience?

Thanks in advance.

You could try to rebuild the Fedora 16 SRPM libbsd-0.2.0-4.fc15.src.rpm.

I haven't thought about that. I will do that. If it all works, i can build a bumblebee rpm.

Please update the thread with your progress. If it works others will be interested.

I installed bumblebee.

First i edited the makefile autoconfig on centos 6 is 2.63
Install the kernel-devel package
Install automake
Install dkms from epel.

The rebuild of the libbsd package was the right solution, install them both.

I installed bumblebee, and copied over the bumblebee sysvinit script.
I then used the bbswitch installation option with dkms from this guide:

The laptop lifetime is extended to 2,30 hours, which is a lot better.

But i will have to test further.

Excellent news. Please keep us posted if anything changes.

If feeling adventurous it would be interesting to see how it plays with ELRepo kmod-nvidia rather than dkms.

I will keep the thread updated. I installed centos on a external usb hard drive, so that i can test easily.
I will have a look at the ELrepo repo.

To bad the hardware suppliers don't write drivers about the hybrid cards.

Thanks. As you have demonstrated that it works, perhaps an ELRepo RFE would be appropriate. As you seem to be comfortable building packages, you might even want to volunteer to help. :-)

If i read the documentation, the kmod-nvidia can replace bbswitch?

No, I don't think so, but it might replace akmod-nvidia, and it might be possible to replace bbswitch with a kmod and not require dkms.
