I have elementary OS 0.4 Loki (based on Ubuntu 16.04.2 LTS) on a Macbook Pro (Retina).
Yesterday i installed the HWE Kernel and Xorg. apt install --install-recommends linux-generic-hwe-16.04 xserver-xorg- hwe-16.04 Today i rebootet the system since the resolution of the display was strange after suspend. But then i had only tty, no desktop. I rebootet again and everything was normal again. But the reported problem is still the case: davidak@unibook:~$ systemctl status gpu-manager.service ● gpu-manager.service - Detect the available GPUs and deal with any system changes Loaded: loaded (/lib/systemd/system/gpu-manager.service; enabled; vendor preset: enabled) Active: inactive (dead) since Do 2017-03-09 10:16:36 CET; 15min ago Process: 1013 ExecStart=/usr/bin/gpu-manager --log /var/log/gpu-manager.log (code=exited, status=0/SUCCESS) Main PID: 1013 (code=exited, status=0/SUCCESS) Mär 09 10:16:36 unibook systemd[1]: Starting Detect the available GPUs and deal with any system changes...

Not sure if it is related since people have it also with stock xenial. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1369216 Title: gpu-manager: /etc/modprobe.d is not a file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1369216/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
