Title:
webapp-container fails to inhibit screen blanking
Status in Webapps for Ubuntu Touch:
New
Status in “apparmor-easyprof-ubuntu” package in Ubuntu:
Confirmed
Bug description:
When watching a video in the youtube webapp, the screen eventually
blanks while the video is playing. I’m seeing this in the app’s log:
[0929/113347:ERROR:logging.h(739)] Failed to call method: com.canonical.Unity.Screen.keepDisplayOn: object_path= /com/canonical/Unity/Screen: org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient, 0 matched rules; type="method_call", sender=":1.110" (uid=32011 pid=11942 comm="webapp-container --webappUrlPatterns=https?://*.yo") interface="com.canonical.Unity.Screen" member="keepDisplayOn" error name="(unset)" requested_reply="0" destination="com.canonical.Unity.Screen" (uid=0 pid=2166 comm="unity-system-compositor --disable-overlays=false -")
[0929/113347:ERROR:oxide_power_save_blocker.cc(109)] Failed to inhibit screen blanking
Playing the same video in the webbrowser app does prevent the screen
from blanking.
