[Bug 1443364] Re: gpu-manager systemd unit is not enabled
I'm experiencing this bug after upgrading from kubuntu 14.10 to 15.04
using the update manager.
Using nvidia-346:
Booting with a previous kernel (3.16) works but I'm stuck in intel mode.
Booting with current kernel (3.19) leaves me with the black screen which can be fixed (until restart) by running the suggested:
sudo systemctl stop sddm
sudo systemctl start gpu-manager
sudo systemctl start sddm
Idk if its relevant but
gpu-manager.conf :
start on (starting lightdm
or starting gdm
or starting kdm
or starting xdm
or starting lxdm)
task
exec gpu-manager --log /var/log/gpu-manager.log
Tried the obvious and added a line "or starting sddm" but didn't work :P

Title:
gpu-manager systemd unit is not enabled
Status in ubuntu-drivers-common package in Ubuntu:
Fix Released
Bug description:
This happened with today's 15.04 image. The gpu-manager unit started,
the xorg.conf was written, and so was the log but, somehow, even
though the log says that the system needs offloading, no /var/lib
/ubuntu-drivers-common/requires_offloading was created. This caused
the system to boot into a black screen.
Starting the same unit after (the failure to) boot, resulted in the
correct creation of /var/lib/ubuntu-drivers-
common/requires_offloading . There is probably something weird going
on in the systemd unit, as gpu-manager has never behaved like this
with Upstart.
This breaks hybrid graphics.
