GLSL Shading makes blender slow. Need advice.

Support Basics & Interface
1

When I switch shading in viewport from Multitexture to GLSL Blender slows down so much that it is impossible to do anything else.

Linux. GeForece GTX 960. Blender 2.78

How can I fix it?
Thanks in advance!

Here I have more detailed description.

Blender Version
Broken: 2.78a e8299c8
Broken: 2.74

Short description of error
When enabling GLSL shading mode in property panel (N) with Texture shading Blender just stuck an seems like it process one action per 30 seconds.

This behavior appear with Blender Render and Blender Game renderers.

Exact steps for others to reproduce the error

  1. With just newly opened blender switch to Texture viewport shading
  2. In property tab (N). Section Shading -> switch from Multitexture to GLSL

Additional words
With default cube created it still works (very slow) but as far as I add more object to a scene it is impossible to use Blender at all.

I will appreciate any help you can provide.
