No splash; monitor powers off before login

[Dave Gilbert]

Since my upgrade to the Quantal alpha I'm not seeing a splash (this is mostly Kubuntu setup on this machine); what I see is:

1) BIOS
2) A grey screen (Kubuntu grey startup screen colour?) - for less than a second
3) Display goes into power save - for probably over 10 seconds
4) The login screen appears

(3) was long enough that at first I'd thought it had died.

It's done this for the last couple of weeks of update.

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

[Andrew Simpson (andrew-simpson)]

Much the same as Comment #1. New install (with old home directory on separate partition and saved). AMD64 Kubuntu 12.10 on i5 with Radeon HD 6450.

Shutting down with multiple users causes the system to 'hang' and require cntrl-alt-del. I think because the dialog box in Kubuntu for shutting down other users wasn't showing up.

Changing from DVI to VGA cables has no effect. Playing with BIOS for on-board i5 video has no effect.

Added 'plymouth:debug' to kernel boot, and resulting log is attached.

Changed from open source Radeon driver to ATI proprietary (using 'additional drivers') and plymouth works as normal.

I've got the same problem in Linux Mint: for less than three seconds (time between os selection in GRUB and login screen) my display powers off instead off showing the plymouth splash screen.
Weird though, since I got the splash screen the first couple of times I booted. I cannot recall, that I changed anything, that would effect plymouth. Although I'm just remembering that I had to reinstall GRUB2, because it had been installed in the Windows boot sector (I've got a dualboot system) instead of the MBR and Windows wouldn't boot anymore. But I couldn't say if that was the time when the splashscreen had gone...
