New Bug report received and forwarded. Copy sent to Debian GNOME Maintainers <[email protected]>.
(Thu, 04 Jan 2018 18:09:06 GMT) (full text, mbox, link).
Package: gnome-shell
Version: 3.22.3-3
Severity: important
Sometimes when the laptop lid is closed it doesn't really go to sleep.
Sometimes after opening it the desktop doesn't come back, just a black
screen or flickering screen.
In one instance, after opening it again, it was observed that the X
screen (tty2) was black and flickering every few seconds. Pressing
CTRL-ALT-F1 showed the X screen (tty1) for a new user login but pressing
CTRL-ALT-F2 again went back to the flickering screen.
I was able to log in on tty3 and run journalctl, it found this:
Error setting property 'PowerSaveMode' on interface
org.gnome.Mutter.DisplayConfig: Timeout was reached (g-io-error-quark, 24)
I searched for that in a search engine and found this:
https://bugzilla.redhat.com/show_bug.cgi?id=1401382
Checking the memory usage of the gnome-shell process I found it was at
400MB. I tried to kill it and it wouldn't stop. Then I used kill -9
and it stopped and a few moments later a new gnome-shell process was
started and I was able to use the system again, all the desktop windows
were still present as they were before.
I've saved a copy of the full journalctl output from the day when this
happened. At the time when I closed the log includes a few errors:
org.gnome.Shell.desktop[1797]: Window manager warning: Failed to set
power save mode for output eDP-1: Permission denied
17:14:06 gnome-shell[1797]: JS ERROR: TypeError: item is undefined
17:14:06
NMConnectionDevice<._activeConnectionChanged@resource:///org/gnome/shell/ui/status/network.js:388
wrapper@resource:///org/gnome/gjs/modules/lang.js:178
17:14:09 systemd-sleep[16824]: Suspending system...
and about 20 seconds later more messages about, like this:
17:14:29 kernel: PM: Preparing system for sleep (mem)
but I think those started appearing after I opened the lid again because
it wasn't really sleeping.
Regards,
Daniel
