Comment 4 for bug 1823573

I can't seem to figure out how to boot to an older kernel on this laptop. Shift and Escape does noting, while the menus opened by F-buttons fail to give advanced boot settings. It's all within the UEFI safety net (which I kind of appreciate after years of BIOS trouble).

I know I have old kernel versions installed (if dpkg --list | grep linux-image is anything to go by).

If it's any help, pavucontrol also fails to detect the headset, while "bluetoothctl" returns "Agent registered // [Beoplay H8]#". So given that pavucontrol is completely separate from Gnome control center, this should not be a GUI problem?

I'm sorry for not being more helpful!
