The dialog box saying low graphics mode allows me to exit to console, if
I do that, I can see on console 7 (ALT+F7):
[FAILED] Failed to start Light Display Manager.
See "systemctl status lightdm.service" for details.
[DEPEND] Dependency failed for Graphical Interface.

Title:
Xserver does not start on boot (low-graphics mode)
Status in xorg package in Ubuntu:
New
Bug description:
After upgrading to (32bit) vivid I hadn't got any problem, but since a
day (daily upgraded) booting results in a dialog saying low graphics
mode and a dialog window about this. Choosing running in default mode
causes to boot splash to be shown forever. if I choose exit to
console, log in then service stop then start for lightdm, it works
then though. Maybe is not Xserver bug, but the new init system
(systemd) race condition of starting things, or such?
