For some reason, the mouse pointer on my Ubuntu 10.04 PC disappears after the computer is woken up from suspend. That PC is missing a keyboard, so I can fix this by logging via ssh, and issuing:

sudo service gdm restart

... however, this basically restarts gnome, and will close any applications that may have been running.

Another way to solve this is to set up that PC as a synergy slave - and then move the mouse from the synergy master to the slave desktop; this brings the mouse pointer back.

Is it possible to run some command, such that I don't need to restart X (or gdm) but I'll effectively restart the mouse pointer code? Then I could put this into a script on the desktop, and be able to recover the mouse pointer after suspend without needing a second machine (even with the mouse pointer invisible, mouseovers on icons are still rendered, so I could target this icon).

this may fix the problem.

If you are stuck with no mouse movement on your laptop (touchpad) then press the key combinations Alt+F2 and type in

gksudo modprobe -r psmouse

Type in the password, press enter, and then press Alt+F2 again for entering the following

gksudo modprobe psmouse

Thats it. Your mouse pointer will start working again.

If you like to do it through the terminal, then type in gnome-terminal after pressing Alt+F2 When the terminal open up type the following

sudo modprobe -r psmouse

or

sudo modprobe psmouse

If your usb mouse is getting stuck, then use the following command after pressing Alt+F2

gksudo /etc/init.d/hotplug restart

Hi @BlueXrider - many thanks for your answer! That PC "is missing a keyboard", so I cannot press Alt-F2 :) However, I tried the sudo modprobe psmouse via ssh, and that unfortunately does not show the mouse pointer after suspend wake (apparently, this is gnome bug, not mouse driver bug). Ubuntu 10.04 also complains: "sudo: /etc/init.d/hotplug: command not found"... Cheers! –  sdaau Apr 2 '12 at 6:42

Finally, found a solution for this:

From #696855 - How do you hide the mouse pointer under Linux/X11? - Stack Overflow; I heard about unclutter, so just ran

sudo apt-get install unclutter

And then put the following in a script on the desktop, called, say unclutter.sh:

unclutter -idle 1 -root -grab -visible

... and make sure you've done chmod +x unclutter.sh.

Then, after the mouse pointer disappears after suspend, use mouseover of icons to target the script and run it; this will start unclutter, which will simply hide (the already invisible) mouse pointer after 1 second of mouse inactivity; but then when you move the mouse after that, finally the mouse pointer will show :) ... however note that to stop unclutter after that, you'd have to do from terminal:

sudo killall unclutter

... as unclutter would be, at that point, running in the background.


Note: also tried, via #15 / Bug #337926 “vino: mouse cursor stays in upper left corner” : Bugs : “vino” package : Ubuntu, to use:

xdotool mousemove 100 100

but this does not make the mouse pointer show again.

Btw, one can look in the synergy source, WebSVN - synergy - /trunk/, and the "reset" of the mouse pointer seems to be coded in ./lib/platform/CXWindowsScreen.cpp.

If you are using a USB mouse, and are on location with the computer in question, then the first thing you should try is to unplug the mouse for a moment and then plug it back in.

Works for me every time.

I hibernate my computer each night and very occasionally upon awakening, the mouse pointer is missing but my USB keyboard works.
