Mouse clicks suddenly stopped working in Ubuntu

I just had this exact behaviour, caused by Nautilus catching a keypress combo & opening a dialog behind several other windows.

• mouse movement but no click detected
• across all input devices
• regardless of window chosen
• keyboard inputs & shortcuts all fine, could run machine
• CTRL-ALT-F1 gave alternate X login, keyclicks accepted on the login screen
• Logged back into session, no mouse input.

Whilst closing windows to prepare for a restart, I found what appeared to be a nautilus popout menu, I think for creating a folder. This was apparently not near a folder window. Mousing over the popout menu caused it to highlight & I was able to ESC to cancel it.

And with that the mouse input devices work again.

This is a patched 20.04LTS, multimonitor, virtualbox guest running (but shutdown when I found the entry).

So worth checking that there are no errant popup dialogs or open menus hiding behind your open windows before starting to reinstall things.

My problem was on a linux laptop. I had it hooked up to external screens and an external keyboard with the laptop lid closed. That's my normal work setup. When mouse clicking stopped working, I was just about to restart the computer, so I opened up my laptop lid (external mouse still didn't work) and clicked on the power options. As soon as i did that, my external mouse click started working again. Super weird.

For anyone using i3, restarting i3 fixed it for me (ctrl+shift+r)

My symptom was mouse movement working but not clicking.

If you are running the gnome variant or the new unity that used gnome as the default:

alt + f2
gnome-shell --replace

Happened to me while experimenting with a graphics API (vulkan). I have seen it happen other time as well

Some things to try:

• Switch to and from a virtual terminal Ctrl + Alt + F1,Alt + F7.
• Activate the screen-lock Ctrl + Alt + L to hopefully reset the X11 window manager.
• Restart the window manager with something like ( DISPLAY=0.0 marco --replace ). You need to replace marco with whatever window manager you are running (compiz, unity, metacity, ...).
• Close any virtual machines, VNC clients, games, etc. that might have grabbed the mouse. For example: killall vmplayer might initiate a virtual-machine suspend operation.

from personal experience (Ubuntu 14.04, logitech wireless mouse) :

2 ways to get it working again for a short time 1 - unplugging and replugging the mouse, 2 - alt-F1 to switch to text mode then alt-F7 (or F8) to switch back to graphics

very recently completely removing "mousetweeak" seems to have resolved a particularly nasty case of "no left click"

my problems used to be infrequent and unplugging the mouse would fix it for a few days, but the most recent case had me working the USB plug every 2 minutes.

for now after the above mentioned uninstall - it seems to be working

EDIT: spoke too soon, problem persists

For what it's worth, I went into the package manager and searched for, 'mouse'. After that, I clicked on all the already installed applications (there aren't that many) and reinstalled all of 'em. Then I searched for 'keyboard' and did the same thing. Not much change there, either. Finally, I searched for 'input' and found a file called, 'inputattach'. Reinstalled it and my mouse problems are solved. Works like it did on the day I installed 10.04. It's so nice to have a mouse that behaves itself and works like it should, again.

I'm a relatively new Ubuntu user, but instead of asking a lot of questions and then waiting for someone to reply, I decided to try and do something about it on my own, and solved my mouse problems (computer mouse, that is...;)

What the file re-installation cleared up, was the need to click several times to open up a folder, having to hold the button down for sometimes as long as three or four seconds before the click would be activated, or having to right click to open a folder or open a file with a particular application.

Just wanted to share this with you since the 'input' of my mouse now seems to once again, be completely and fully 'attached' to my computer.

I've had, perhaps a similar issue, thought I would chime in on what I did that seems to have worked. BTW, I'm using a wireless Logitech trackball on Ubuntu 10.04.

My issue was that the left button on my Logitech wireless trackball mouse would give me lots of problems. Sometimes it would be severe, sometimes barely noticeable. Clicking would sometimes register as a left click, sometimes register as a double click, and many, many times it would fail to register at all. Dragging and dropping and copy and paste became almost impossible. I could almost never manage to highlight text. In short, life with this mouse became unbearable. This problem affected all programs and windows.

I assumed the problem was with the mouse, even though I've only had it since June or July this year (2010). I focused my efforts on trying to fix the mouse. In the end, I essentially gimped up this mouse trying to make it work, but to no avail.

Finally, I stopped using the mouse completely, and switched to a wired trackball that had never previously given me any problems before. However, after using the wired mouse for a few days, I started to notice that it was having the exact same problem. So, then I realized that in all likelihood, this is a problem with 10.04.

After looking around online for some time trying to come across a solution that worked for me, I stumbled across the post above about using metacity --replace. So, based on that, I was pretty certain that Compiz was the root of my mouse issues. After playing around with Ubuntu Tweak, one of the menu options, "Enable Metacity's compositing feature", mentioned that I had to manually disable visual effects in appearance.

So, after disabling Visual Effects (System>Preferences>Appearance>Visual Effects then select None), the mouse is suddenly working again. I don't know if this will be a permanent solution or if it will start giving me problems again, but I thought I'd mention this solution.

Did not have any mouse issues until a recent update manager update. Suspected my wireless mouse, but had the same effects with a regular wired mouse: left mouse button would work on and off.

Reinstalling the xorg mouse input drivers which were already installed by default (xserver-xorg-input-mouse, xserver-xorg-input-evdev) did not change anything, but, seeing how many mouse drivers were installed by default made me wonder: will I ever use a Synaptics Touchpad on this desktop? I realized this is not Gentoo, and, many unnecessary drivers are installed by default to Ubuntu work across a wide hardware spectrum.

What solved my issue was to uninstall all xorg mouse drivers for devices which were very unlikely to ever be connected to my system. As soon as the superfluous drivers were uninstalled, my mouse clicks were back to normal.

I would also like to add that I have never needed the workaround mentioned above, i.e. setting the GDK_xxxxx environment variable. I have been running Compiz and Chrome on this system without ever needing this workaround. The only application that does not appear to like the mouse in conjunction with Compiz is Blender3d.....mouse clicks in this application are off by some 20 pixels vertically.

It would happen to my ubuntu 10.04 every now and then too, and it only worked again after I clicked the touchpad button. However, it has never happened again ever since I changed my touchpad setting. I deactivated the tap-click of my touchpad, and now the "real" mouse never stalls.

Got this one too. The odd thing is, it doesn't take clicks from my mouse, but it fully recognizes my touchpad.

Anyway, opening a terminal (e.g., with Ctrl+Alt+T) and typing:

metacity --replace &

will make it work if you're using compiz. If you want compiz back, type:

compiz --replace &

and the mouse will work again.

It's easier getting to the terminal if you have Gnome-Do or if you assign a hotkey to it (like the super/windows key or tilde (~).

WARNING: Don't stop metacity/compiz commands once started or you'll be in worse situation than you were before.

WARNING 2: The above command can force to log out, but still it's useful for issues like:

• command key (super key) doesn't work
• left click doesn't work

I found that this was just a problem with the mouse. The left button has pretty much stopped working. Other buttons seemed to stop working because the left button gets "jammed". After restarting with the other mouse plugged in, it worked fine.

Damn, I seem to have gone through so many mice and/or keyboards recently...

From the bug mentioned by Joe above (emphasis mine):

So here the bug and workarounds.

For example on youtube, whilst it recognises my mouse moving over various buttons, actual mouse clicks are not recognised. I can navigate using 'tab' but this is very painful. I can also right click. The problem doesn't occur with other flash players, e.g. swfdec-mozilla.

WORKAROUND 1: Disable compiz
WORKAROUND 2: Remove flashplugin-nonfree / flashplugin-installer and install from adobe
WORKAROUND 3: Open a terminal and enter:

   gksudo gedit /usr/lib/nspluginwrapper/i386/linux/npviewer

Then add: export GDK_NATIVE_WINDOWS=1 before the last line of text.

Note: The only workaround for Chrome/Chromium users is to disable compiz.

Mostly this may be reason :

The bug is well known. Look for example here:

A common workaround is exporting GDK_NATIVE_WINDOWS=1 before running the application with click problems.
