I have Ubuntu 12.04 installed, and I'm trying to create a minimal Chrome browser only setup, and have tried adding our script that runs google-chrome to .xinitrc and running startx (this answer:

I'm experiencing significantly worse performance in Chrome (framerates on animations, etc) than when I run the browser from within gnome in Ubuntu 12.04.

I'm trying to understand the difference in performance. Is gnome allowing Chrome to use the video card / GPU in some way, and we're losing this benefit in the standalone xsession?

Looks like problem was solved by updating Nvida drivers & xorg.conf. This worked:

  1. Run:

    sudo apt-get install nvidia-current nvidia-settings
  2. Reboot into command line.

  3. After starting X, chrome performance was as good as when running in Gnome.
