neilbags, as per http://www.dell.com/support/home/us/en/19/product- support/product/optiplex-755/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A22).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, 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 ** Tags added: bios-outdated-a22 ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1507446/+attachment/4499702/+files/ProcEnviron.txt ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1507446/+attachment/4499701/+files/Dependencies.txt -- 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/1507446 Title: monitor goes into power save after boot Status in xorg package in Ubuntu: Incomplete Bug description: This is happening a few seconds after X starts - i can see the mouse pointer for a second then display goes to sleep.
