Hi,
thanks for your comment on this. I'm running into simmilar issue:
root at lisabook2:~# echo "low">
/sys/class/drm/card0/device/power_dpm_force_performance_level
-bash: echo: write error: Invalid argument
I'm also on a hybrid platform: MBP 8,2 with linux-3.14.0
I recently noticed this, that I can't set this value when I use the machine
*without* an external Monitor which I usually don't.
Does it mean that the kernel now switches automatically to the non dGPU, when
the dGPU is not in use? Would be great news.
