Айдеед, as per http://www.dell.com/support/home/us/en/19/product-support/product/optiplex-755/drivers an update to your BIOS is available (A22). 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, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags removed: 14 intel q35 ** Tags added: bios-outdated-a22 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1393205 Title: Intel q35 bug on Ubuntu 14.04 (Screen Artifacts) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1393205/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
