My LEAP 15 Desktop was update from 42.3 using zypper dup procedure.
Nothing seemed unusual as the update proceeded.
The boot process takes a very long time buy openSUSE standards, something fails and I am dumped to a level 3 console.
I login as root, issue init 5 and system immediately displays a Greeter and login from there as user proceeds normally.
Once up, system seems very responsive and all functionality tried so far is fine.
I did pull this info after hacking about in various Forum items
I have no idea where else to look for info on what is going on during boot.
Is there a way to monitor the console during boot, i.e. un-hide it from behind the “bouncing diamond above down carot” screen?
Sorry, not much to go on, but I am unsure what would be useful information.
The easiest way is to hit the ESC key as soon as you see that graphic.
However: I had a similar problem for one of my installs. And hitting ESC did not reveal the problem.
Another option: On the boot menu, hit the ‘e’ key. That gets you into an editor window to edit the boot commands.
Scroll down until you find a line starting “linux” (or might be “linuxefi”). Perhaps hit the END key to get to the end of that line. But then back up a little. Find the string “splash=silent” and remove that string. Then continue booting (CTRL-X).
That should give more detail. That’s how I found the problem on my one system that had difficulties. (It was doing a 90 second delay waiting for a file system that was never going to show up – essentially the same problem as in bug 1071354).
As splash= is an optional kernel parameter, splash=verbose equates to splash=0, as well as the null string nrickert “applied”. I don’t know whether it directly affects Plymouth at all, since I never have it installed, but any of those equivalents turn off the boot message suppression that splash=silent causes.
In my case, I’m pretty sure that plymouth is still running, but it isn’t showing its splash screen. So I see the boot messages. These include a message that password requests (for crypto) are being passed to plymouth.
