bbswitch fails to start on Fedora 28

[ideskov]

Hi,

I just installed bumblebee on my Dell XPS 15 with GeForce GTX 1050 Ti Mobile running Fedora 28.

Output from $ systemctl status bumblebeed.service

● bumblebeed.service - Bumblebee C Daemon Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; enabled; vendor preset: disabled) Active: active (running) since Sat 2018-08-18 19:47:53 BST; 14min ago Main PID: 964 (bumblebeed) Tasks: 1 (limit: 4915) Memory: 2.2M CGroup: /system.slice/bumblebeed.service └─964 /usr/sbin/bumblebeed Aug 18 19:47:53 chocho systemd[1]: Started Bumblebee C Daemon.

I did try running $ sudo /usr/sbin/bumblebeed

And the result was similar:

modprobe: ERROR: could not insert 'bbswitch': Operation not permitted [ 628.862822] [ERROR]Module bbswitch could not be loaded (timeout?) [ 628.862833] [WARN]No switching method available. The dedicated card will always be on. [ 628.863988] [INFO]/usr/sbin/bumblebeed 3.2.1 started

Please let us know if you need more info.

Thanks

Possibly a selinux policy issue, please seek help with Fedora help channels.

Also note that you might have to add acpi_rev_override=1 to your kernel command line in order to avoid hangs with your laptop model.

That was to do with the fact that I had secure boot enabled and bbswitch was unsigned. Couldn't be bothered signing the module, so just disabled secure boot and bbswitch is now loading ok.

I've also added that property to my kernel command line. Thanks for your help
