Package: bbswitch-dkms
Version: 0.8-1~bpo70+1
Severity: important

Dear Maintainer,

I have platform with i915 (Celeron 1037U) and nvidia 705m. I wish to disable discrete video, so i installed bbswitch.
After "echo OFF > /proc/acpi/bbswitch" the status is still "ON". Dmesg shows "bbswitch: disabling discrete graphics" with no errors.
What additional information do I need to send you to solve this problem?
