I am running Ubuntu 22.04 with the Mate desktop. Yesterday, when I returned to my desk, the laptop screen was black. I clicked the mouse, but it didn't wake up. I thought it was frozen, so I performed a hard reset by pressing the power button for five seconds. Afterward, I noticed that it was lagging and getting stuck at the BIOS logo for a while during boot. The day before, I had upgraded the kernel to:
uname -a
Linux whatnext 5.15.0-72-generic #79-Ubuntu SMP Wed Apr 19 08:22:18 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Despite the lagging at the BIOS, the system eventually boots and runs well.
I also noticed an error in the log, but it was there for a long time, so I believe it is unrelated:
Loading X.509 certificate: UEFI:db
[ 0.834706] integrity: Problem loading X.509 certificate -65
[ 0.834710] fbcon: Taking over console
Would you please assist me?
