[tlug] FYI, bumblebee working on Ubuntu 13.04

[Raymond Wan <rwan.kyoto@example.com>]

Hi all,

Just a follow-up to an old discussion a while ago about 
laptop purchase.  I think I said I was having problems with 
my laptop because it uses NVidia's Optimus technology to 
switch the load between two graphics adapters [1].

I had mentioned I had problems getting bumblebee working. 
That was about a year ago.  Well, I gave it another go today 
and was successful [2]:


$ optirun glxspheres
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: GeForce GT 555M/PCIe/SSE2
95.623734 frames/sec - 106.716087 Mpixels/sec
97.848188 frames/sec - 109.198577 Mpixels/sec
96.924654 frames/sec - 108.167914 Mpixels/sec
98.724338 frames/sec - 110.176361 Mpixels/sec

$ glxspheres
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: Mesa DRI Intel(R) Sandybridge Mobile
61.534920 frames/sec - 68.672971 Mpixels/sec
59.990038 frames/sec - 66.948883 Mpixels/sec
60.069071 frames/sec - 67.037083 Mpixels/sec


It probably can't switch between the two adapters as 
seamlessly as Windows, but it's a good start...

Not sure if this is of use to anyone...  Perhaps most of you 
would be smarter than me and look into Linux support before 
buying a laptop!  :-(
