Could someone with a L502x and Linux try this?

Optimus on Linux Problem Solved | Martin Juhl's Blog

If you could post the results here that would be great.

 

Could anyone try this possibly?

 

Has no one got a L502 with Linux installed?

 

Hi pinsb,

I have partially tried this and it looks promising.
I have an L502X and comparing glxgears and "optirun64 glxgears" (2 seperate runs in the terminal) I get notable differences of FPS rates.

I need to compile the acpi_call kernel module which goes with the Bumblebee script but don't have much time in the next 2 weeks. I hope to finalise this and post to the corresponding website (as they requested). I can also do so here to your thread if you want.

for now...


[without optirun64]

Code:

~$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
298 frames in 5.0 seconds = 59.441 FPS
299 frames in 5.0 seconds = 59.565 FPS
299 frames in 5.0 seconds = 59.697 FPS
299 frames in 5.0 seconds = 59.630 FPS
299 frames in 5.0 seconds = 59.631 FPS

[With optirun64]

Code:

michael@XPS-L502X:~$ optirun64 glxgears
 * Starting Bumblebee X server bumblebee                                        FATAL: Module acpi_call not found.

                                                                         [ OK ]

3030 frames in 5.0 seconds = 605.841 FPS
2973 frames in 5.0 seconds = 594.190 FPS

error messages will disappear after acpi_call is compiled.
