http://bugzilla.opensuse.org/show_bug.cgi?id=1120655 Bug ID: 1120655 Summary: Machine unresponsive after screen turned off Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: malte.kraus@suse.com QA Contact: qa-bugs@suse.de CC: atoptsoglou@suse.com Found By: --- Blocker: --- On a Dell Latitude 7490, some time after locking the screen (on Gnome), the computer becomes unresponsive - some LEDs are still blinking, but there's no way to get the screen to turn back on. (I haven't yet tried SSHing into the machine in that state.) Note that this doesn't happen immediately - right after locking the screen, the lock screen can still be unlocked. After waiting a bit, sometimes it's in this unresponsive state. The last messages before the (forced) reboot in /var/log/messages are as follows: 2019-01-03T14:48:23.166843+01:00 linux-r9va dbus-daemon[1492]: [system] Activating via systemd: service name='org.freedesktop.nm_dispatcher' unit='dbus-org.freedesktop.nm-dispatcher.service' requested by ':1.7' (uid=0 pid=1722 comm="/usr/sbin/NetworkManager --no-daemon ") 2019-01-03T14:48:23.172078+01:00 linux-r9va systemd[1]: Starting Network Manager Script Dispatcher Service... 2019-01-03T14:48:23.180329+01:00 linux-r9va dbus-daemon[1492]: [system] Successfully activated service 'org.freedesktop.nm_dispatcher' 2019-01-03T14:48:23.181000+01:00 linux-r9va systemd[1]: Started Network Manager Script Dispatcher Service. 2019-01-03T14:48:56.478390+01:00 linux-r9va gsd-media-keys[3259]: Couldn't lock screen: Timeout was reached This only started after or around Christmas, but it's happening a few times a day now. My colleague Alexandros (in CC) is seeing a similar/the same problem on the same hardware. I'm reporting this against the kernel, because I got a kernel update on my machine on Dec 21st, and I can't see any e.g. Gnome or Wayland packages updated in that timeframe. -- You are receiving this mail because: You are on the CC list for the bug.
