When I need to use my webcam I switch the display configuration to unified output and the same image is displayed on both monitors. I have KDE configured to not suspend when the lid is closed if a monitor is connected. Also under battery and brightness I have "manually block sleep and screen locking" checked. What desktop environment are you using? Is the external monitor still plugged in? How is the external monitor configured: unified, extended or primary? You say you disabled suspend via grub? Have you tried disabling suspend in the BIOS? It will be S2 and S3 in BIOS. When the device suspends I take it that you are not able to wake the device properly by pressing the power button? > Enviado do meu iPhone > -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄⠀⠀
