Hello, I found that when starting the dkms service, every dkms module is loaded right after, even the ones that are blacklisted. The behavior is avoidable by adding the '-b' option to modprobe, in the dkms start script (/usr/lib/systemd/scripts/dkms), line 26. I don't see any drawback in adding this option, and the resulting behavior seems more intuitive in my option. It would also help prevent some issues as the one described here: https://bbs.archlinux.org/viewtopic.php?id=189032 Basically when using bumblebee and nvidia-dkms, the dkms service loads the nvidia and nvidia_uvm module after bumblebeed starts, which powers the discrete graphic card back on indefinitely. I wasn't sure if I should directly post an issue on the bugtracker, or first discuss about it here. Cheers Simon
