Lost of speed/stamina switch when updating to 2.6.31-16

 

Hello,

I am really happy with Raphael's script on my VGN-Z31WN. Everything worked like a charm. Thanks a lot for that work.

Then, my kernel was automatically updated to 2.6.31-16, and, thanks to dkms, sony-laptop was rebuild immediately.

However, no more switch anymore, my laptop was using only the INTEL card. I tried rerun the janitor script: no success. It told me that everything was OK.

I checked /etc/default/grub and found:
GRUB_CMDLINE_LINUX=""
So, I changed to:
GRUB_CMDLINE_LINUX="acpi_osi=\\\"!Windows 2006\\\""
Then, I rebboted twice and it was fixed.

Would it be possible that kernel update reset GRUB_CMDLINE_LINUX=""? If so, could the /etc/default/grub modification be included in the dkms procedure (i am ignorant about that) or at least in the script (when rerun for maintenance) ?

Thanks for your help,

Pierre
