Sometimes, when booting, I get:
- ubuntu purple background
- Grey backlit screen
- Black screen
And nothing else. It does seem that Ubuntu is correctly booted. To fix the issue, I can put the computer to sleep and back again, and then the screen will be OK. I am certain that ubuntu is booted because, during the black screen, I typed enter, then my password, then I poped a
terminal. After that, I did the "fix" routine and confirmed that I had an open
terminal in my session.
I am unsure where to look at as most questions related to this cannot boot at all.
I did a video recording of the failed boot, I suspect this is clearer than my explanation.
Here are the 4 lines that flashes, from
[ 20.065643] ACPI Error: Needed type [Reference], found [Integer] 00000000214ff4c5 (20181213/exresop-69) [ 20.065656] ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [Store] (20181213/dswexec-427) [ 20.065700] No Arguments are initialized for method [RPPC] [ 20.065704] ACPI Error: Method parse/execution failed \_SB.PCI0.LPCB.EC0.RPPC, AE_AML_OPERAND_TYPE (20181213/psparse-531) [ 20.065716] ACPI Error: Method parse/execution failed \_SB.PCI0.LPCB.EC0._Q04, AE_AML_OPERAND_TYPE (20181213/psparse-531)
Looking these up didn't yield anything helpful for me but I might have missed crucial information as I've got no idea what's happening. I've seen driver related answers, telling to install them from Ubuntu's "additional drivers" tool if they appear; there's nothing here for me.
Questions are therefore:
- What other information can I provide to diagnostic what happens?
- How to fix this?
Edit 1: I tried both kernel options at boot: 5.0 and 4.18, didnt' help
