** Description changed: After upgrading to Ubuntu Gnome 16.04 LTS, the screen power saver started to malfunction. When the desktop is idle, it turn off the screen as usual, but a second later it turns the screen back on. This happens repeatedly. I have disconnected any input device as well. I'm using Ubuntu gnome 16.04 with kernel version: 4.4.0-21-generic x86_64 This is the syslog entries from the moment the power-saver mode was started: - Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): resizing framebuffer to 1680x1050 - Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none - Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): resizing framebuffer to 3600x1080 - Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on HDMI2 using pipe 0, position (0, 0), rotation normal, reflection none - Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on VGA1 using pipe 1, position (1920, 30), rotation normal, reflection none - Apr 27 16:09:32 Funaro-Home gnome-session[1165]: (gnome-shell:1390): GLib-GObject-WARNING **: /build/glib2.0-t9oPgV/glib2.0-2.48.0/./gobject/gsignal.c:2635: instance '0x2e02040' has no handler with id '71399' - Apr 27 16:09:32 Funaro-Home gnome-session[1165]: (gnome-shell:1390): GLib-GObject-WARNING **: /build/glib2.0-t9oPgV/glib2.0-2.48.0/./gobject/gsignal.c:2635: instance '0x2e02040' has no handler with id '71399' - Apr 27 16:09:36 Funaro-Home gnome-session[1165]: Gjs-Message: JS LOG: Device -> - Apr 27 16:09:36 Funaro-Home dbus[737]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' - Apr 27 16:09:36 Funaro-Home systemd[1]: Starting Hostname Service... - Apr 27 16:09:36 Funaro-Home dbus[737]: [system] Successfully activated service 'org.freedesktop.hostname1' - Apr 27 16:09:36 Funaro-Home systemd[1]: Started Hostname Service. - Apr 27 16:09:36 Funaro-Home gnome-session[1165]: Gjs-Message: JS LOG: [FREON] Render all MenuItems + Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): resizing framebuffer to 1680x1050 + Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on VGA1 using pipe 0, position (0, 0), rotation normal, reflection none + Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): resizing framebuffer to 3600x1080 + Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on HDMI2 using pipe 0, position (0, 0), rotation normal, reflection none + Apr 27 16:09:31 Funaro-Home /usr/lib/gdm3/gdm-x-session[1152]: (II) intel(0): switch to mode [email protected] on VGA1 using pipe 1, position (1920, 30), rotation normal, reflection none + Apr 27 16:09:32 Funaro-Home gnome-session[1165]: (gnome-shell:1390): GLib-GObject-WARNING **: /build/glib2.0-t9oPgV/glib2.0-2.48.0/./gobject/gsignal.c:2635: instance '0x2e02040' has no handler with id '71399' + Apr 27 16:09:32 Funaro-Home gnome-session[1165]: (gnome-shell:1390): GLib-GObject-WARNING **: /build/glib2.0-t9oPgV/glib2.0-2.48.0/./gobject/gsignal.c:2635: instance '0x2e02040' has no handler with id '71399' + Apr 27 16:09:36 Funaro-Home gnome-session[1165]: Gjs-Message: JS LOG: Device -> + Apr 27 16:09:36 Funaro-Home dbus[737]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' + Apr 27 16:09:36 Funaro-Home systemd[1]: Starting Hostname Service... + Apr 27 16:09:36 Funaro-Home dbus[737]: [system] Successfully activated service 'org.freedesktop.hostname1' + Apr 27 16:09:36 Funaro-Home systemd[1]: Started Hostname Service. + Apr 27 16:09:36 Funaro-Home gnome-session[1165]: Gjs-Message: JS LOG: [FREON] Render all MenuItems Edit: kernel version 4.5 fixed the errors with intel drm (see updated log above), but the problem remains the same.
