Adding this in case it helps identifying what is going on. Here is the upper part of a screen capture. The red dot is the position of the mouse cursor at the time of the capture. Notice how the "g"s above the y-position of the cursor have a glitch, but not the one below. This happens systematically in Thunderbird and updates as the mouse cursor moves (there is a form of hysteresis : when the mouse cursor moves down, a line is affected after the cursor has passed the line below it ; when moving up, the glitch ceases for a given line only when the cursor reaches it).

After unlocking screen cursor is invisible. Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7) cursor returns ==================== no matter if you suspend or sleep, to swap or disk when you return from it, the mouse cursor is missing. you can still move the mouse and you can see (because it highlights the window) as you move it around. But the cursor is not displayed on the screen. i am using a lenovo W540 laptop. I downloaded the latest beta on april 8 2016. this is xubuntu using the xfce window manager. the cursor does return if i log off and log back in, but that actually defeats the purpose of going to sleep. --- ApportVersion: 2.20.1-0ubuntu1 Architecture: amd64 DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2016-04-08 (2 days ago) InstallationMedia: Xubuntu 16.04 LTS "Xenial Xerus" - Beta amd64 (20160323) NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia Package: light-locker 1.7.0-2ubuntu1 PackageArchitecture: amd64 ProcEnviron: LANGUAGE=en_US TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.4.0-18.34-generic 4.4.6 Tags: xenial Uname: Linux 4.4.0-18-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1568604/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
