Random black screen/crashing with graphical glitches

General system Newbie
21

Just restarted with iommu=pt and this is the result: http://ix.io/3rtv

I figure it’s hard to say much given that it hasn’t had much run time. Regardless thanks for the help, I can perhaps look into some of the other kernel params if it happens again.

22

Original crash happened quicker than expected this time: http://ix.io/3rtx.

I am curious if it has anything to do with setting iommu=pt or if that was just circumstantial

23

The thing i see is the recurring keyboard errors. You could add acpi_backlight=vendor for the keyboard for the backlighting. I have a version of that command slightly different and it gets rid of the backlight error. You have many other errors related to the keyboard functions so I’m not sure what they are from. The backlighting parameter is a normal one for Lenovo. Also you could try iommu=soft and or also amd_iommu=pt which is slightly different.

24

Which errors specifically? Just so I know what to look for.

It’s funny it’s a keyboard error though, because my keyboard doesn’t have a backlight.

I’ll try with the other kernel parameters, I seem to recall trying acpi_backlight=vendor before and it disabling my screen backlight control. But I can try again.

25

It’s the panel back lighting actually and you can adjust it with the function keys. My HP has it and it works. If you look at the last log you posted the errors are these and they repeat a number of times during the boot.

The errors on the keyboard also may be related to language. I see us and dk in the log? :man_shrugging:
