Double-click instead of single-click in Ubuntu 12.04

Question

When I do a single click, my computer (with Ubuntu 12.04) acts like it was double click. I think it happens in ~50% of cases.

It happens with all the program I use: browsers, file manager, terminal and so on. I'm not sure when exactly it started, maybe a week ago, and I don't remember if it started to happen after system-update or after the installation of some packages.

What I tried:

change mouse
change mouse settings like Double-Click Timeout

None of those helped me. Any ideas?

UPDATE

This bug has disappeared after upgrading to 12.10.

You can also make sure that it's not a hardware failure by simply trying out another mouse. — zerwas, Oct 14 '12 at 20:12
just ran into the same issue - had a dell mouse for a desktop PC; replaced it - and the fun was over — Grigorash Vasilij, Feb 08 '13 at 05:41

If you've manually edited xorg.conf, try adding and entry for your mouse, in case it was somehow deleted:

Section "InputDevice"
# generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

EDIT As mention in the comments, this seems to be a reported bug that has stood for some time now. It may be best to add your info to Launchpad to help resolve the bug in the future.

Thanks for the answer, I added this section to `xorg.conf` but it didn't help :( – evfwcqcg Oct 10 '12 at 18:19
I copied and pasted straight from the forum, so you may want to check the settings I've provided to match what you have. – Kyle Macey Oct 10 '12 at 18:37

I had the same problem on my laptop running Ubuntu 14.04.

Solution: If you are using a laptop try taking out its battery and then inserting it back.

Explanation: The problem was possibly caused by battery of my laptop. I noticed that though my laptop was fully charged and plugged in, its battery LED was changing color between orange (indicating charging) and yellow (indicating fully charged) continuously. So I removed my battery and inserted back to its slot (didn't switch off my laptop, so everything else remained same). This solved the issue, and since then the touch-pad is working perfectly fine.

I had the same happen to me for no apparent reason a few days ago on 12.04. I went to nautilus Preferences..Behaviour and it had "Double click" option selected. I then selected single click, checked that was working, then went back and changed to double click again and bingo! Its back in double click mode!
