Bug#891385: bumblebeed fails to unload nvidia kernel module

[Pavel Kreuzt]

Package: bumblebee
Version: 3.2.1-17
Severity: important

When I launch some program with primusrun or optirun and close it, nvidia kernel module keeps loaded in kernel. Bumblebeed shows this error on syslog:

Feb 25 12:53:52 Harken bumblebeed[18893]: [ 3106.839895] [ERROR]Failed to unload module 'nvidia' (ref count: 1).

Keeping the kernel module loaded seems to affect battery performance and temperature of laptop.
