One of the main driver things that I have to install is the video card. My laptop has a discrete video card. Without installing the driver, the graphics seem to work pretty well, but with the driver, I get a very noticeable improvement in power consumption. After installing the driver, the battery lasts significantly longer. Also, glxspheres does a nice job of showing the graphics performance difference with and without the acceleration.
For the discrete video card, you need to install Bumblebee. Here’s what I found:
sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee bumblebee-nvidia
Previously, I had an issue with the nvidia driver version. I think that is cleared up now:
sudo apt-get install apt-show-versions apt-show-versions nvidia-current
Then, I had to edit /etc/bumblebee/xorg.conf.nvidia (sudo vi /etc/bumblebee/xorg.conf.nvidia). I set the ConnectedMonitor option to none.
And, I edited /etc/bumblebee/bumblebee.conf (sudo vi /etc/bumblebee/bumblebee.conf).
Unfortunately, this didn’t work. I was still missing something.
Removed the custom repository:
sudo ppa-purge ppa:bumblebee/stable
Installed the packages:
sudo apt-get purge bbswitch-dkms bumblebee-nvidia bumblebee
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
I also changed the ConnectedMonitor settings to CRT:
I am not sure whether it was adding the ubuntu-x-swat repository or changing the ConnectedMonitor option. Either way, it worked for me, and I didn’t want to mess with it afterward.
