My assumption is that this is due to spurious movement from the mouse. <p>There is not an explicit way to configure Linux (X11) so that it doesn't exit DPMS sleeps on mouse movement, but I found a tip on the internet to disable the mouse device at the XInput level when activating the screensaver, and reactivating it when the screensaver exits. <p>I don't run a &quot;screensaver application&quot; so wiring into things like dbus for notification doesn't work. Instead, I wrote an X program which polls the requested DPMS state and enables or disables the mouse device accordingly. <p>It remains to be seen whether this solves the problem which causes the display to turn on multiple times per night, but it might just fix it. <p>You'll need to customize the program by changing the &quot;device_name&quot; string in the source to match your own input device. If you have multiple input devices, then more extensive work will be required. <p>License: GPL v3+ <p><b>Files currently attached to this page:</b> <table cellpadding=5 style="width:auto!important; clear:none!important"><col><col style="text-align: right"><tr bgcolor=#eeeeee><td><a href="https://media.unpythonic.net/emergent-files/01554669749/nobump.c">nobump.c</a></td><td>2.0kB</td></tr></table><p>
