left click stops working after a while

[KushalSharma]

I did a clean install of Quantal a few days ago. I have a five year old Lenovo N100 3000 laptop. The install went smoothly and everything worked fine until later this evening. This started happening when playing scrabble on Facebook. The clicks would stop working. After a restart, it would work normally, but after an hour or so, it would stop working.

I know this isn't a hardware issue, because I plugged in a USB mouse as well, and it had the same problem when the left click (and even right click on one occasion) wasn't working on my trackpad (tapping on the trackpad for left click stopped working too).

How do I find out what's causing this, and more importantly, how do I fix it?

P.S. I'll add an update in case it works fine if I don't use the Scrabble app.

Same experience here, I can verify this can be reproduced.

Status changed to 'Confirmed' because the bug affects multiple users.

Mouse buttons stopped working after about an hour, but everything goes fine if I switch app to fullscreen mode (F11). Non-responsive to either button otherwise.

[Andrey Sidorov (andrey-desman)]

At the same time panel accepts clicks just fine. It all looks like panel grabs all the clicks in non-fullscreen mode.

This is what I get if I run xwininfo on regular window. It is HUD who takes all the mouse events.

$ xwininfo

xwininfo: Please select the window about which you
          would like information by clicking the
          mouse in that window.

Pressing <Alt> on keyboard resolved the issue for me.

Wow!
My exact issue!
I also have the old timey 3000 N100 :D
But with dual boot vista/ubuntu 12.10

But for me the system detects that the mouse pointer is there, because buttons light up etc., but I cannot click anything... Not even the date and time icon!

So pressing Alt is the only solution? No permanent one?

Same problem on a 3000 C200, Ubuntu 12.10, fresh install.

I am using Ubuntu 12.10 on a realitively new system (~2 year old, frankenstein). It seems that Ubuntu stops registering clicks from the mouse outside of the top bar and the Unity launcher on the side.
Mouse will move fine but cannot click on any window or program outside of the two system bars.

I know my temrinology isn't perfect but I have the same issue as every one else.

[Jacob Woodfield (spudguyongaming)]

This is affecting me also. Fresh install of 12.10 dual boot with Windows 7 Pro 64. Can't click on any application windows.

[Thomas Juberg (thomas-juberg)]

Also experiencing this issue under Gnome3, Gnome Classic, Unity and Awesome.
Mouse button presses not registering, but mouse movement works.

Going out of X to a virtual console and back fixes it temporarily.
Using google-chrome seems to trigger this most easily for me, but other gtk applications also triggered it.

[Laurent Redor (laurent-redor)]

I have the same issue on a new Asus Zenbook prime UX31A-R4003P.

For me, it seems that the problem appears when I use VirtualBox. Suddenly, the mouse click does not work anymore on the laptop screen but it works on my external screen (HDMI one).

If I click <<Alt>> key as said by Andrey Sidorov, this solves the problem.

KushalSharma, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-input-synaptics REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
