Not sure exactly what category to put this in, but ‘Plasma’ seemed the most likely. I have an LG Gram laptop running the Plasma spin. All updates current.
I’m not sure if this is a common experience, but the power policies regarding sleep, monitor brightness, etc, do not trigger the ‘AC charging’ profile when the laptop is being charged via the USB-C port. This is usually only an annoyance, as I have to manually tick the ‘Inhibit sleep’ box, but I forgot to do that today and the machine dropped into sleep state in the middle of a kernel update today, and became un-bootable stating:
error: file '/boot/vmlinuz-5.14-x86' not found.
Fall back doesn’t work either. I’m still working on getting it back up. Has anybody experienced this before? Any other useful information I should query before I reinstall? Thanks.
