@awe: great progress! well done! :) I took a few videos to demonstrate the problem on my device KRILLIN, RC-PROPOSED, R163 network-manager 0.9.10.0-4ubuntu15.1.8 wpa-supplicant
It was really easy to shoot videos at the right time because the problem happens exactly every 2 mins (which is the scanning interval Tony reported above) DISCLAIMER: The problem can actually get worse than what the first video shows (if I wait one or two days more) NO SERVICES DISABLED https://www.youtube.com/watch?v=UvGoX4Nh9oo SLPGWD DISABLED https://www.youtube.com/watch?v=-Vhd0eS5Af4 SLPGWD POSCLIENTD DISABLED https://www.youtube.com/watch?v=bTPiT2-LP2Y SLPGWD POSCLIENTD LOCATION-SERVICE DISABLED https://www.youtube.com/watch?v=V4SXNfJ9SqM Then I looked for more location/here related services in the system, and I disabled them as well SLPGWD POSCLIENTD LOCATION-SERVICE INDICATOR-LOCATION DISABLED https://www.youtube.com/watch?v=2QuED_1UzEw SLPGWD POSCLIENTD LOCATION-SERVICE INDICATOR-LOCATION LOCATION-SERVICE-TRUST-STORED DISABLED https://www.youtube.com/watch?v=9QgssDKDu1Q As can be seen from the videos, disabling SLPGWD is the change that made most of the difference, disabling POSCLIENTD also improved the situation a bit. Disabling the rest of the services brought very little to no advantage, as far as I can tell. However, as Tony was correctly saying, even after disabling everything, there's still a 1sec freeze every time a WiFi scan happens...and that can be quite annoying, especially when the scanning interval is much shorter than 2 mins. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1480877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
