I am running Ubuntu on an Acer Aspire ES1-411 (P6B1). There's also an identical Bug filled with Acer Aspire ES1-311 and both Ubuntu 15.04 & 15.10 by Christian Wansart here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723 I have no clue what causes this, my system just freezes and I can't do anything anymore. When it happens, I have tried the following secuence without any luck, I have to power down manually: 1. ALT + F2, type xkill + ENTER. 2. Press Alt+Ctrl+F1. 3. While holding Alt and the SysReq (Print Screen) keys, type REISUB. Last time I was only viewing a Youtube video using Firefox. I checked some log files but I couldn't find anything suspicious. Any ideas?
