Giacomo Gabriele, thank you for reporting this and helping make Ubuntu better. As per http://www.asus.com/Notebooks_Ultrabooks/N550JK/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (208). 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, and the information above is provided, then please mark this report Status New. Thank you for your understanding. ** Tags added: bios-outdated-208 ** Changed in: xorg (Ubuntu) Importance: Undecided =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 Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1343404 Title: screen freezes often and randomly Status in xorg package in Ubuntu: Incomplete Bug description: the screen freezes often and randomly. by pressing ctrl + alt + f [1-6] and after ctrl + alt + f7 the system returns to normal until the next block.
