NVIDIA on Linux: monitor stays black after suspend until you replug the cable (workaround)

NVIDIA on Linux: monitor stays black after suspend until you replug the cable

The symptom

  • After resume, and sometimes after the monitor's own standby, the monitor stays black or shows "No signal".
  • The system is alive. You can type your password blind or log in over SSH.
  • The monitor is still listed as connected and enabled (hyprctl monitors, kscreen-doctor -o, /sys/class/drm/*/status).
  • Replugging the cable, or switching to a TTY and back, brings the picture back.
  • Windows on the same PC and monitor wakes up fine.
