  • Check if zram is enabled:
    lsmod | grep -i zram
  • Enable zram with a dynamic number of devices (use `zramctl` to configure devices further):
    sudo modprobe zram
  • Enable zram with exactly 2 devices:
    sudo modprobe zram num_devices=2
  • Find and initialize the next free zram device to a 2 GB virtual drive using LZ4 compression:
    sudo zramctl --find --size 2GB --algorithm lz4
  • List currently initialized devices:
    zramctl
