David Chan, thank you for reporting this and helping make Ubuntu better. As per http://www.gigabyte.com/products/product-page.aspx?pid=5124#bios an update to your computer's buggy and outdated BIOS is available (F9). 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 ** Tags added: bios-outdated-f9 ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1497102 Title: sloppy mouse focus lags everything Status in xorg package in Ubuntu: Incomplete Bug description: when i have sloppy mouse focus set there is a noticable delay between moving my mouse and focusing on the new window additionally if i rapidly move my mouse between windows the lag grows. the interface is unresponsive during lag. for example if i open glxgears and rapidly move my mouse between several windows the gears stop until focus is achieved depending on how long i've been rapidly moving my mouse this may be several seconds. this interferes with video playback as well.
