I discussed the issue with Andrea Azzarone and Martin Pitt, and the problem might be related to the signal coming from UPower not being reliable enough. We should really rely upon the PrepareForSleep signal coming from org.freedesktop.login1.Manager.
We should also make sure that PrepareForSleep returns False (as this means that the system has just resumed) Something like the attached patch only with the "proxy_.Connect" line changed (so as to check that PrepareForSleep returns False) should work. ** Patch added: "use_logind_draft_1.patch" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1210077/+attachment/4030604/+files/use_logind_draft_1.patch ** Changed in: unity (Ubuntu) Assignee: (unassigned) => Andrea Azzarone (andyrock) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1210077 Title: Screen freeze and garbled after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1210077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
