I'm seeing something like this on a 32bit Acer laptop - with Intel graphics - running Kubuntu 18.04.1 - it's been doing it for quite a long time - but it's still a current bug - I did a full apt upgrade/update just today.
When the machine awakes from a sleep (eg with by closing and opening the lid) the mouse cursor is gone - and the whole screen below the mouse position is white. So as you move the mouse up and down and it covers and uncovers the entire screen. You have no way to tell where the X position of the mouse is - but it does seem to work and you can still click on things. Switching to a different virtual console and back again using Ctrl-Alt- Fn seems to fix it...until the machine goes to sleep again. Seems like maybe some piece of graphics state isn't being properly saved and restored. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1568604 Title: Mouse cursor lost when unlocking with Intel graphics To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1568604/+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
