You can disable mouse and keyboard input using xinput --list to list the input devices by name and id, then using xinput --disable device-or-id for each of the real mouse and keyboard devices. To reverse use --enable.

Alternatively, you can use sudo evtest --grab /dev/input/eventN & where N is the number of the input device. The grab lasts until the process is interrupted.

Another thing to try is setting the screen to stay on in the Xserver, then use ddccontrol to talk directly to the monitor over the DDC I2C bus. If the monitor is recognised, you can give a command to turn it off. Presumably, the Xserver will not try to turn it on if it assumes it is still on.
