Upgrading to a non-LTS version has it's downsides, and I have read reports of people that experience the same problems after upgrading up to 17.04.
I now installed an Intel version of the 21.20.16.4590 driver for Windows 10 from the Lenovo website, but it's actually not meant for the P50 laptop with Intel P530 graphics but for the X260 and T460 instead with Intel P520 graphics: http://pcsupport.lenovo.com/nl/en/downloads/ds105823. It installed without complaining though, but I don't know if it also tried to replace the graphics firmware ... ... the mouse pointer is still flickering and dissapearing though. I'll try to get Lenovo's attention on this issue. -- 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/1664397 Title: Mouse trails and distorted cursor on 2nd monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1664397/+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
