Lightdm does not start on a netboot of Kubuntu 13.04

[lordievader]

When booting the Kubuntu 13.04 daily-image (2013-02-07) over the network (pxe/netboot), lightdm fails to start automatically. There is no mention of lightdm in the syslog, and if you start lighdm manually it starts without errors.

Ubuntu version: Kubuntu 13.04 daily (2013-02-07)
Lighdm version: 1.4.0-0ubuntu3
Expected: Lighdm to start automatically
What happend: Got to tty1, lightdm doesn't seem to even try to start.

I'm not sure if it is related with this.

I got a Laptop with amd graphics, Radeon HD 4200 and a discrete Radeon HD 5650 (both mobility).

Lightdm does not load with the default configuration (with discrete graphics ON) but it start with the integrated graphics.

I have switcheroo configured to turn off de discrete graphics in rc.local so when it boots it does not load Lightdm because rc.local goes after lightdm load, so I have to enter start lightdm in a tty in order to load it.

If I try to load manually lightdm with the discrete graphic card, it does no load at all.

Status changed to 'Confirmed' because the bug affects multiple users.

Same here. I have a Dell Vostro A90 with a Minimal KDE install, and lightdm as the DM, running 13.04 daily updates . It is set up to autologin. In thefin last couple days, upon reboot, the computer comes to a command line login. You can login, and then run "sudo lightdm", or "sudo service lightdm start". In both cases it works just fine. I suspect upstart is not running lightdm anymore, and this seems a regression.

I'll play with BUM if I have some time, to confirm. Cheers!

Confirmed! I launched BUM, and lightdm was not selected. I activated it, rebooted, and everything is back to normal (the graphical login goes on normally). Hope this helps!
