I tried to improve my battery life using
Slackware Nvidia optimus docs. I exactly followed the documentation (the manual way).
However, it made my battery life even worse. I realized that my Nvidia gpu is still on since
returns:
Bumblebee status: Ready (3.2.1-2013-04-26-Format:%h$). X inactive. Discrete video card is on.
- I believe that the default status of Nvidia GPU should be
off. Could someone please give me the output of
optirun --status on their optimus laptop?
- I managed to optimise the power consumption by turning Nvidia GPU off manually:
Code:
# rmmod nvidia_drm nvidia_modeset nvidia
# tee <<<OFF /proc/acpi/bbswitch
Now optirun --status returns:Bumblebee status: Ready (3.2.1-2013-04-26-Format:%h$). X inactive. Discrete video card is off.
- Furthermore, I don't need to turn the 2nd GPU on manually when I need it, because it is automatically turned on on demand (But unofrotunately, it remains on again since then). Therefore, what I intend to do is to set bumblebee and bbswitch to turn the 2nd GPU off when it is not used, but I have no idea how to do that. Could someone help me with this?
Many thanks.
