The bug prevents use of systems "blessed" with nvidia optimus. It has been fixed however. https://github.com/systemd/systemd/issues/6908
I hope the fix can be incorporated into bionic, because it would be sad to have an LTS release that can not turn of the nvidia GPU without rebooting the system. Of course the fix is to upgrade to systemd 238, and the new bugs in 238 are fixed in 238+10. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1720131 Title: logind holds open file descriptor to DRI nodes, preventing nvidia suspend Status in systemd: Fix Released Status in systemd package in Ubuntu: Confirmed Bug description: The nvidia binary kernel driver now creates /dev/dri/card? nodes. When switching between the nvidia and intel drivers on a hybrid system, all holders of the DRI node need to relinquished so that the nvidia driver can be unloaded so that bbswitch can turn the card off. In order for switching hybrid graphics to not require a reboot, logind needs to close its file descriptor to the nvidia DRI node.
