There were no crash files..but the ui would not respond in any way to touch/mouse input. I was able to replicate this 3x in a row. on N4, I followed roughly the same steps - open ubuntu apps, then puritine, i even opened all the puritine apps at once. I was able to hotplug 20x just fine, no reboots required, no freeze etc. subsequently i tried N7 once more, just having the Dash open and then launching FF, it survived one plug+unplug+plug...i let sit for some moments, i then mouse to move the ff window (i think it began to resize as i missed the target) and in an instant froze, hdmi remote screen went black and the device screen maintained the "you are connected to a monitor" billboard - unplugging, the billboard just remained. Feels like a potential memory issues....could it be that the n4 kernel is tuned better, n7 is more sensitive ? hard to tell if this may effect other devices similar to N7 To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-pocket-desktop/+bug/1532979/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
