Comment 31 for bug 1386721

The problem described by Matthew Tucker-Simmons, affect me too on an acer 5742 g notebook with intel/nVidia drivers (Optimus).

The bash is very slow and it take more than a second to type a letter in the search box.

Moreover: when I use Gnome Shell and stast gnome monitor, a CPU core is always at 49%-50%

Considering going back to 14.04 where everything was OK
