Comment 50 for bug 1872159

Thanks James. My configuration is different: the laptops in question are in mechanical docks. The laptop remains closed (lid down); external display is connected to the dock via HDMI, external keyboard and mouse are also connected to the dock via USB dongle in the dock. So I can't start them and then plug in the monitor very well: the external display has to be primary.

I've also had this spinning logo and the forced powerdown that it forced result in ACPI errors on the subsequent boots and shutdowns. We're not sure whether this bug corrupted the ACPI table, or whether turning off the splash screen exposed a latent bug in the BIOS. This is on a T440s.

I have changed splash quiet to splash noquiet and that -- so far -- avoids this hang with the spinning logo; but then I get the laptop going into suspend as soon as the login password is entered. I'm not sure whether the two bugs are related in terms of cause or not.

At first, I tried to just restart the docked machine to resume out of suspend; but over a period of days Ubuntu became unstable. So I tried to reload Ubuntu, and encountered the bug where the installer now crashes when the third-party driver option is selected. I need that for nvidia and sierra wireless hardware. Result is that machine is now sidelined, with numerous failed reinstallation attempts.

I'm using a backup machine (which does NOT have any nvidia). I have grub changed to nosplash. But I'm still getting the suspend on login problem... so I'm just hoping that the developers get these bugs fixed before the second machine goes down. Again, bug numbers for the other 3 items are in post 45 above.

We've got a T480 also, but it uses an external display connected to the dock via DVI AND the laptop is run open with its own internal display as primary. I'm hoping that I won't see problems there. So far so good with that configuration, knock on wood...
