Public bug reported: I tried Ubuntu 18.04 beta from a USB stick and encountered a few issues:
1. Shutdown seems to often (but not always) "hang", the console still accepts text I type but it doesn't want to actually complete it. Ctrl+Alt+Del "finishes" it. 2. After I booted Ubuntu, the laptop makes very loud and weird random noises, even as early as the BIOS/UEFI stage, before the bootloader. If I then boot into Windows 10, the crackling and static noises continue until I reboot the box again. This *only* happens the first boot into Windows after using Ubuntu. Sound in Ubuntu appears to work fine. I don't know how to best describe the loud noises, so I recorded a short video: https://vimeo.com/264778133 Here's the output of lshw: ubuntu description: Notebook product: 14Z980-A.AAS7U1 vendor: LG
