Clarification: On an older system with BIOS and no manufacturers logo (see platform above), screen may be blank throughout loading of OS.

Suggest to check system to see if manufacturer's logo is available, if not, display the elementary OS logo in supported monitor resolution.

I'm also affected by this, and the lack of a splash screen, which looks like plymouth malfunctioning, has the side effect of exposing the boot log to the screen in framebuffer mode when logging off the user session back to the greeter, or rebooting/shutting down.

This doesn't happen in the equivalent Ubuntu and Kubuntu installations, as I've tried over the past couple of days.

Hardware:
Lenovo ThinkPad T410s (2013)
CPU: Intel i5 540-M
Dual graphics (Optimus): Intel HD Graphics (Ironlake) + NVIDIA NVS3100M (512Mb, nouveau driver)

I don't believe this is an issue with the greeter. Try running update-alternatives --config default.plymouth as root to switch the theme (It may have gotten changed)

I had done this previously, but I'll try again tonight.

UPDATE:

Based on my shell history, I had already tried and failed.
Tried again, failed again.

However, I followed an advice on editing /usr/share/plymouth/themes/elementary/elementary.plymouth and changing every instance of UseFirmwareBackground to false, then running update-initramfs -u -k all, and rebooting.

At least a spinner icon shows up. Not the elementary OS logo, though.

Is this really a Greeter issue? Or rather a Plymouth issue? elementary/plymouth-theme#17

[stradicat]

After having found that other issue, I've concluded that it's a plymouth issue and not a greeter problem, as initially suspected.

[4jNsY6fCVqZv]

Perhaps this issue can be closed as duplicate or out of scope (for Greeter) if the elementary team can provide feedback on this issue?

[stradicat]

It's definitely a duplicate of the same problem, so it can be closed.

[davidmhewitt]

This is definitely not a greeter issue, the linked elementary/plymouth-theme#17 issue is the correct place for this and there are additional details there. So I'm closing this as a duplicate.
