Since my upgrade to 42.2, I have no boot splash anymore: it’s a complete black screen until the KDE splash screen appears. No ESC, F1 or F2 will work to show verbose mode.

00:01.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R6 Graphics] [1002:130a]
Subsystem: Hewlett-Packard Company Device [103c:221c]
Kernel driver in use: radeon
How can I fix this?
how did you upgrade from a dvd/usb or on the fly with zypper?
post your repo list
zypper lr -d
I upgraded on a running system with zypper dup.
However, the problem does not occur anymore. I have figured out that I had the fglrx driver before the upgrade and that it was missing after the upgrade. What I did:
- reinstalled fglrx drivers and rebooted -> could not start X because of some fglrx driver issues
- removed the drivers for proper uninstallation and rebooted -> proper booting with plymouth but with the ??? bug
- after some reboots, ??? got replaced by the proposer theme
So, in the end, it works, although I cannot explain how the ??? plymouth screen got fixed. I understand that fglrx driver will not work on Leap 42.2 anymore.
Actually, this issue has not been resolved. It turns out to have quite randoom behavior. Each time that I boot, I get one of the three scenarios:
- black screen until KDE splash
- the three question marks in green
- the regular splash screen that I would like to systematically see instead of the above two
How can we further diagnose the root cause? On a side note, I am running from an USB drive (but it did not affect my Leap 42.1 boot splash before the upgrade).
I’ve seen that too sometime I get the graphic and sometime the text and some times just black seems to be related updates and if a kernel is updated, But it is just eye candy and I don’t really pay any attention
It’s a Plymouth issue, possibly an AMD-only issue, in my case possibly a dying Hybrid 1TB Hard-Drive (SMART End-to-End errors).
It’s been reported with Bug 1008489 “Leap 42.2 RC2 - Plymouth dumps core during booting”.
