Saren Taşçıyan, as per http://support.lenovo.com/us/en/products/Laptops- and-netbooks/ThinkPad-T-Series-laptops/ThinkPad- T450s?linkTrack=Homepage:Body_Search%20Products&beta=true an update to your computer's buggy and outdated BIOS is available (1.20). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
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: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status New. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags removed: desktop firefox xorg ** Tags added: bios-outdated-1.20 ** Package changed: xorg-server (Ubuntu) => xorg (Ubuntu) ** 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-server in Ubuntu. https://bugs.launchpad.net/bugs/1535394 Title: Xorg crashes at certain wiki pages via firefox Status in xorg package in Ubuntu: Incomplete Bug description: Hi, I am having a weird problem in Ubuntu and I will try to explain when it happens. When I open Wikipedia main page or View history on any wiki page, sometimes (not always) Xorg (I suppose) freezes (UI becomes unresponsive for a while about 10-60 seconds) until it jumps to login screen. If I login, I need to start all the application all over again. Firefox starts but if I repeat the same process (visiting the same web page) Xorg crashes again. The two pages so far this behaviour occurs are: http://en.wikipedia.org (main page, I can however directly open any article and navigate from there) http://imagej.net/index.php?title=ImgLib2_Examples&action=history (history page of a wiki page) There are no dialogs after the crash reporting about a crash. I really don't know how to track the problem to find the cause. Even though Firefox is chrashing, Xorg should not be affected.
