Anupam Datta, thank you for reporting this and helping make Ubuntu better. Please answer all of the following questions:
1) Could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description, or the result of a terminal command)? 2) Is this something that started to happen after a package update? If so, which and when precisely? 3) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** 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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761549 Title: Screen flickering, whenever went to lock, waking up creates problem.
