Prasanna Kannappan, thank you for reporting this and helping make Ubuntu better. Please advise to all of the following:
1) Is this something that started to happen after an update? If so, which one and when precisely? 2) As per nvidia.com the latest proprietary driver compatible with your card is 390.59. Would using the nvidia proprietary driver provide a WORKAROUND via https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia ? 3) To see if this is already resolved in Ubuntu, could you please test the latest release via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Tags added: bios-outdated-1.50 ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1770679 Title: Erratic mouse pointer trails and flickering Status in xorg package in Ubuntu: Incomplete Bug description: I am using a Lenovo P50 laptop.
