Christian Wansart, thank you for reporting this and helping make Ubuntu better.
As per http://us.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (1.11). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.1 ** Tags removed: bios-outdated-1.1 ** Tags added: bios-outdated-1.11 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509723 Title: Ubuntu freezes occasionally Status in linux package in Ubuntu: Incomplete Bug description: I am running Ubuntu 15.10 and my notebook freezes occasionally. I had the same issue with Ubuntu 15.04, but I thought that 15.10 might change it. I am running Ubuntu on an Acer Aspire ES1-311 (P1D5). I have no clue what causes this, my system just freezes and I can't do anything anymore. ctrl+alt+f1 doesn't work as well as alt+print+REISUB doesn't work either. It's just frozen. I have to power down manually. Last time I was programming only with a gnome-terminal and atom (editor) opened. I checked some log files but I couldn't find anything suspicious. Any ideas?
