Every third or fourth time that I resume my Acer Aspire S7-392 (suspending works every time), the screen is completely frozen, though my mouse can move. There is nothing that I can do to make it responsive except going to TTY1 and entering sudo service lightdm restart
. This is obviously not desirable behavior.
When I resume, there is a bug report that has the same error message as this bug report: https://bugs.launchpad.net/ubuntu/+source/upower/+bug/1305699. I have CC'd myself to that bug.
Given that it's been open and unassigned for over a year, is there any workaround to getting my suspend working? I wish I had enough knowledge about upowerd to go in and fix it myself :)
