Hi Gert, I might have the same problem. Can you switch to another terminal with ctrl + alt + F2? If yes, try logging in with your standard user and checking if light-locker is running. Kill it with 'killall light-locker', then switch back to your X with ctrl + alt + F1. If that works, there's a bug in light-locker.
Yves-Alexis, current X in testing/sid run rootless, the logs are not written to /var/log/Xorg.0.log anymore. You can find them by running 'journalctl -u session-1.scope', if the X session is your first. Otherwise check for other sessions via 'systemctl'. For me, I have the exact same symptoms (unresponsive X after resume), which was triggered by the following change in xfce-session: xfce4-session (4.12.1-4) - replace recommendation on xscreensaver by light-locker I usually use xscreensaver, and this pulled in light-locker. Looking into my xfce4 "session & startup", I can see that *both* xscreensaver and light-locker were started at the same time. This can be seen in session-1 logs: Jun 21 16:19:59 saito /usr/lib/gdm3/gdm-x-session[1569]: xscreensaver: 16:19:59: couldn't grab pointer! (AlreadyGrabbed) Jun 21 16:19:59 saito /usr/lib/gdm3/gdm-x-session[1569]: xscreensaver: 16:19:59: unable to grab keyboard or mouse! Blanking aborted. Running 'killall light-locker' solved the symptom for me. Attached you will find the logs of 'light-locker --debug', from resuming to killing it. I'm no expert with DBUS, so I'm out of depth debugging this, but it looks like the problem is somewhere there. Regards, Lee
