I have sucessfully installed bumblebee and bbswitch. One thing that isn't working now is the power management of the laptop. If I try to suspend/restart/shutdown, it instead just hangs.
I tried a couple of things to narrow the problem down, but come to a dead end. What I've tried so far:
no bumblebee and card enabled: works
bo bumblebee and card disabled: freezes
bumblebee and card enabled: freezes
bumblebee and card disabled: freezes
bumblebee and bbswitch unloaded: works
I also set the following in /etc/bumblebee/bumblebee.conf
TurnCardOffAtExit=false
And enabled the following systemd service:
[Unit]
Description=Enable NVIDIA card
DefaultDependencies=no
[Service]
Type=oneshot
ExecStart=/bin/sh -c 'echo ON > /proc/acpi/bbswitch'
[Install]
WantedBy=shutdown.target
WantedBy=hibernate.target
WantedBy=hybrid-sleep.target
WantedBy=reboot.target
WantedBy=sleep.target
WantedBy=suspend.target
Unfortunately those didn't work either.
The Laptop is a Lenovo Thinkpad T440P with a Geforce GT 730M
