Following idea from comment #40, if bug still exists it's enough just to press Ctrl+F7, to push display refresh. But at 2016-09-01 with updated 4.4.0-36-generic kernel and X.org server version 1.18.3 this bug seems fixed after locking/unlocking.

Switching VTs again may cause the cursor to become visible again. - Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7) This is often observed in systems that lock the session and return to the greeter (including at least Xubuntu, Ubuntu Mate, and elementary OS). [Test Case] (Requires a lightdm-based screen locking solution) 1. Start a new session. 2. Lock your screen. 2a. You are redirected to the lightdm greeter. 3. Login/Unlock your session. 4. Cursor is no longer visible. [Regression Potential] remains to be seen === [Original Report] Cursor is visible at unlock screen either after returning from suspend or just locking. 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/elementaryos/+bug/1568604/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
