As a workaround, I've found that switching between virtual consoles (Ctrl-Alt-F1 then Ctrl-Alt-F7) brings the pointer back.

Confirm bug (and virtual console quick fix) for Xubuntu 16.04 on a HP Stream 13. Usually I do a clean installation on a different 10GB root partition, but this time I did an upgrade from 15.10 and therefore cannot easily revert - I'm not going to do that again.

I'm getting the same bug. As a workaround, if I do ctrl+alt+f1 to switch to a text console and then back to ctrl+alt+f7 to the graphics I get my mouse back. Still sucks to have to do it every time I lock my screen.

[Albert Zang (albertzang-ys)]

Yes confirmed with my Thinkpad T410 as well. Fresh new installation of xubuntu 16.04

[Samuel Lampa (samuel-lampa)]

Just as a sidepoint, I noticed that switching screen resolutions in the display menu, also restores the mouse pointer.

[gthemean (gthemean)]

Also affecting my HP 250 G4 Laptop.

[Paul Taylor (paul-taylor-london)]

This bug seems to lie in the code the requires a password
atfer closing the laptop lid, rather than in the screensaver.

Aside from the fact that the pointer disappears, this code that
is supposedly for security shows the prior screen display after
the laptop lid is opened, before blanking and asking for the login.

This is a security hazard in the event that the laptop has been
stolen because the contents of the display might be confidential.

I have a HP Stream 13 with Xubuntu 16.04

XFCE Power Manager
Power Manager Settings

General:

when power button is pressed - do nothing
when sleep button is pressed - do nothing
when hibernate button is pressed - do nothing

tick - handle display brightness keys

when laptop lis is closed - on battery, suspend - plugged in, suspecnt

tick - show notifications
tick - show system tray icon

Security:

Automatically lock the session - never
Delay locking after screensave for - 1 seconds [= minimum]

unticked - lock screen when system is going for sleep

[Please can we change these to "1 second" and "going to sleep]

Behaviour with these settings:

I close the lid, wait and reopen it - pointer is still there

I close the lid, wait and reopen it
screen is on when I first open the lid
then screen goes blank, power light flashes
does not wake up when I stroke my finger across the touchpad
does wake up when I hit return
screen comes back, power light is on steadily, pointer is there
pointer disappears when I hit any printing key on the keyboard
(return, space, letters, digits, puctuation)
but not when I hit tab arrows backspace escape
(I am using Emacs)
pointer comes back when I stroke my finger across the touchpad

Change power manager settings:

tick - lock screen when system is going for sleep

I close the lid, wait and reopen it

Sometimes the screen comes on and shows whatever was on it before
(this might be confidential material, so this is a security hazard)
Then screen goes blank if I hit a key
after which it goes to the login screen
but the pointer is shown while the login screen is displayed
The pointer disappears after I have logged in
and does not reappaear when I stroke the touchpad
although it does if I do ctrl-alt-f2 and then ctrl-alt-f7.

[mariac (maria-cerase)]

I am experiencing this issue on ubuntu 16.04 on a lenovo yoga 500. The cursor disappears whenever there is a prolonged period of inactivity due to screen lock or closing the laptop.

[Anish Narayanan (anish-narayanan32)]

I have a similar issue on xubuntu 16.04 whenever I lock the screen or suspend the monitor. When I log back in the mouse cursor is missing. However, when I hit alt-tab to switch applications, the mouse reappears! I am not sure why this works, but it does for me. Can anyone else confirm if this works for them? The tty switch (with ctrl-alt-f2 and ctrl-alt-f7) mentioned in other comments works for me as well.

Same problem, xubuntu 16.04, fresh install, intel graphics.

[whyki (whyki)]

This is long standing problem with Light-locker or graphical driver. The cursor will disappear even if you lock and unlock screen.

Solution which works well for me is to replace light-locker by xscreensaver:

sudo apt-get uninstall light-locker
sudo apt-get install xscreensaver

If the problem on resume persists, enable screen lock when system going for sleep. (xubuntu 16.04)

[whyki (whyki)]

Follow up of my previous post, correct uninstall command is:

sudo apt-get remove light-locker
sudo apt-get install xscreensaver

[Brad Aytes (b-aytes-gmail)]

This may already be solved or known as well however I'm having the same issue. I'm using Ubuntu 16.04 at its base (its Ubuntu Gnome 16.04). I'm using a script to put the machine (i'm on a desktop not lappy) to sleep upon a keyboard shortcut and once it "awakes" I can unlock the machine but the cursor is missing (right click shows the default nautilus menu however, but no cursor) however if I have an open window (or if i open a terminal via a shortcut) already i.e: firefox and alt+tab (or super+tab in my case) the cursor displays. Very odd. I cannot replicate any other time other than resuming from sleep. Any thoughts?

[Ebrael (ebraelshaddai)]

It's wrong to state this bug affects all the 16.04 flavours. I had Ubuntu Mate 16.04 installed in this very notebook and this bug didn't affect it. Since early installed, Xubuntu has presented this bug on my notebook.

Confirmed! As logging back in from Suspend/Lock state, mouse pointer gets invisible, remaining active. This bug also affects the windows display of some apps, like Thunderbird and Caja (I guess not only these): their labels also disappear, icons and frame remaining visible (even panning).

The workaround related (Ctrl+Alt+F1 / Alt+F7) has worked to me, but it sucks. It's a critical bug, of course. I hope 16.10 Alpha release may get out soon, fixing this bug.

[Ebrael (ebraelshaddai)]

Correcting previous comment: where it is read "Thunderbird and Caja", it should be read as "Thunderbird and Thunar" (Caja actually when I'm on Mate).

[Mohammad Anwar Shah (mohammadanwarshah)]

Another victim of this notorious bug! on Intel 965GM graphics board. Switching to Virtual Console with ctrl-alt-f1 and ctrl-alt-f7 works.

[Terry (h-ubuntu-6)]

similar issue with Lubuntu 16.04 64, mouse can not be seen after switching user. The workaround Ctrl-Alt-F1 then Ctrl-Alt-F7 restores it.

[Jose (glitchd1)]

another easy workaround for this is to use a script ive written that turns the monitor/display off, but turns it on for a second when the mouse is moved. the easiest way to use it is to either launch it from a terminal or to assign it to a hotkey. switch it on, the screen turns off, move the mouse, the screen turns back on for a few seconds where you will be able to see your mouse cursor, then either crtl+c with the terminal window in focus to kill the script and the window, or by clicking the shortcut youve created to launch it. not a fix, but another work around.

I see the same problem when I lock my screen (or it goes to sleep) and then wakes back up. I don't suspend the laptop, it's just when the screen blanks. The same fix of switching to a virtual terminal and then back to X works for me. And like others, I've got an Intel video card:

00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

The laptop is a Dell, however, so my guess is this is a bug that's been in the Intel video driver for a while since I'm seeing it on 14.04.

I'm running trusty (14.04.5 LTS) but the driver I have appears to be from xenial (not sure how that happened):

[tony (robalik)]

I literally just got this Oryx Pro from System 76 yesterday and ran into this. However, in my case, the cursor did not disappear immediately after resuming from sleep, but about an hour later. I had just been forced to type my password into a dialog to enable SSH access to my key for github for the first time, and it was at that point the cursor disappeared. There were also a number of strange visual artifacts that appeared, particularly when navigating across workspaces. Various parts of my windows became semi-translucent, particularly the title bar (I could see my wallpaper through it). Restarting fixed it, but I'll try the ctrl-alt-F1 and ctrl-alt-F7 thing next time.

Anyone ever get the impression that desktop Linux simply isn't ready for prime time? A new laptop should have so many issues (wifi not working, cursors disappearing, lockscreen breaking). It's ridiculous.
