Comment 15 for bug 1293384

We might include a setting to control this value, if requested, but for now the easier way to get this enabled at login time is:

sudo gedit /usr/share/gnome-session/sessions/ubuntu.session
Remove "compiz" from the RequiredComponents list

sudo gedit /usr/share/upstart/sessions/unity7.conf:

Add these lines after "export COMPIZ_CONFIG_PROFILE":
env UNITY_LOW_GFX_MODE="1"
export UNITY_LOW_GFX_MODE

Another option might be to just add `export UNITY_LOW_GFX_MODE="1"` to the ~/.profile file, but it didn't work here always.
