Hans-Christian Payer, thank you for reporting this and helping make Ubuntu better.
As per https://www.asus.com/Motherboards/P8Z77V_LE_PLUS/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (0910). 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 New. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-0910 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1517179 Title: Xorg crash Status in xorg package in Ubuntu: Incomplete Bug description: Description: Ubuntu 15.10 Release: 15.10 hans@karma:~/PycharmProjectsâź« apt-cache policy xorg xorg: Installiert: 1:7.7+7ubuntu4 Installationskandidat: 1:7.7+7ubuntu4 Versionstabelle: *** 1:7.7+7ubuntu4 0 500 http://at.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages 100 /var/lib/dpkg/status xorg randomly and quite often (once an hour) crashes back to loginscreen, when klicking on various buttons (you can never say which button). i already filed a bug report (#1515972) as experience the same crashes on my laptop.
