Description Erik Damrose univentionstaff 2014-05-12 17:38:08 CEST
There is a noticable delay during startup while switching from plymouth to lightdm. During this time, a black login tty is visible. We should check init/upstart dependencies.

See also Bug #31126, which changed upstart dependencies
Comment 2 Erik Damrose univentionstaff 2014-05-21 14:53:55 CEST
I changed the dependencies of the involved upstart jobs:
ucc-update does not stop plymouth anymore
plymouth-stop stops plymouth, but waits for lightdm to be start_ed_ (was: start_ing_) and does not trigger on runlevel changes

Comment 3 Moritz Muehlenhoff univentionstaff 2014-05-22 10:16:13 CEST
Tested successfully with the desktop and thin client image:

There is no longer tty output visible when switching between fbdev and LightDM/X11. There's still a black screen for about a second, but that's an unavoidable hardware limitation.

I also tested the installation of an additional package using a UCC software policy (since that's what introduced the new behaviour) and everything was fine as well.
