Public bug reported: My screen randomly stops blanking, ignoring the interval I set under Settings > Power > Power Saving Options > Screen blank (8 minutes). This behaviour behaviour has so far manifested only after I resumed the system from suspend but that connection is not consistent - more often than not, the system resumes without any noticeable impact on screen blanking.
However, when screen blanking does break, it appears to go hand in hand with an unstable gnome session. That is, when I try to restart my gnome session (I am using X), it results in a desktop crash and I am forced to log out. (on a side note: I noticed the other day that gnome also broke when I logged out of my second desktop account to return to my main account; the screen went black and I had to reboot). The crash does not appear to generate a log but journald has recorded the following at/around the time that restarting gnome-shell ended in a crash (the messages are reproduced here in reverse order): nov 04 02:41:46 Dapple gsd-media-keys[3125]: g_dbus_proxy_call_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed nov 04 02:41:45 Dapple systemd[2589]: org.gnome.Shell-disable-extensions.service -

This behaviour behaviour has so far manifested only after I resumed the system from suspend but that connection is not consistent - more often than not, the system resumes without any noticeable impact on screen blanking. However, when screen blanking does break, it appears to go hand in hand with an unstable gnome session. That is, when I try to restart my gnome session (I am using X), it results in a desktop crash and I am forced to log out. (on a side note: I noticed the other day that the system also froze when I logged out of my second desktop account to return to my main account; the screen went black and I had to reboot).

> Power > Power Saving Options > Screen blank (8 minutes). This + My screen randomly stops blanking, ignoring the interval I set under + Settings > Power > Power Saving Options > Screen blank (8 minutes). This behaviour behaviour has so far manifested only after I resumed the system from suspend but that connection is not consistent - more often than not, the system resumes without any noticeable impact on screen blanking. However, when screen blanking does break, it appears to go hand in hand with an unstable gnome session. That is, when I try to restart my gnome session (I am using X), it results in a desktop crash and I am forced to log out. (on a side note: I noticed the other day that the system also froze when I logged out of my second desktop account to return to my main account; the screen went black and I had to reboot). The crash does not appear to generate a log but journald has recorded the following at/around the time that restarting gnome-shell ended in a crash (reproduced here in reverse order): nov 04 02:41:46 Dapple gsd-media-keys[3125]: g_dbus_proxy_call_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed nov 04 02:41:45 Dapple systemd[2589]: org.gnome.Shell-disable-extensions.service -

This behaviour behaviour has so far manifested only after I resumed the system from suspend but that connection is not consistent - more often than not, the system resumes without any noticeable impact on screen blanking. However, when screen blanking does break, it appears to go hand in hand with an unstable gnome session. That is, when I try to restart my gnome session (I am using X), it results in a desktop crash and I am forced to log out. (on a side note: I noticed the other day that gnome also broke when I logged out of my second desktop account to return to my main account; the screen went black and I had to reboot). The crash does not appear to generate a log but journald has recorded the following at/around the time that restarting gnome-shell ended in a - crash (reproduced here in reverse order): + crash (the messages are reproduced here in reverse order): nov 04 02:41:46 Dapple gsd-media-keys[3125]: g_dbus_proxy_call_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed nov 04 02:41:45 Dapple systemd[2589]: org.gnome.Shell-disable-extensions.service -
