Syslog at boot with dmesg output
Starting with the Tumbleweed instance about a week before
openSUSE-release-20190125-8.1.aarch64, the display is magically back to
normal. (I was diverted by another issue and didn't get onto trying to
identify just what went right, just was glad that I can see the screen
again.) I'm still betting on a device tree issue.
This isn't the Raspberry Pi laptop; it's a standard RPi 3B with a HDMI
connection to the monitor. When it failed, the X-server would not
start, sayind "no screens found" in Xorg.0.log, and no video went out to
the monitor, causing the black screen. Now the X-server, display
manager, and desktop are behaving as they did before 2018-12-14. I
haven't had issues with I2C, but haven't tried anything fancy on that
bus, so I wouldn't have noticed problems.
At boot I dump dmesg into syslog, and I've attached all the boot
messages that were logged, but this is for the *working* kernel;
messages from failing versions have rotated into oblivion, sorry. Please
ignore chaotic clock sync, which is "normal" on a RPi (no realtime
clock). Search for "Booting Linux" to find the start of dmesg. We'll
probably never be sure what went wrong in 2018-12-14. Let's close this
report.
