After installing Ubuntu 15.04 when I start the system appears the message, which carries with it takes longer to boot. If anyone can help would be grateful.
Already tested the command:
sudo systemctl enable lightdm.service -f
and got the following result:
Synchronizing state for lightdm.service with sysvinit using update-rc.d... Executing /usr/sbin/update-rc.d lightdm defaults Executing /usr/sbin/update-rc.d lightdm enable The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...).
And the problem still persists. If you can help me would be grateful.
