single click is considered as double click

I experienced this bug too, and it is horrendously annoying. The only workaround I can suggest for the time being is learning to click and drag. You can use this to navigate around the main menus.
Ex: Click on applications, drag down to open menu, drag right to open submneu, release on application.

I only experienced it in failsafe X (working out video problems). With my own xorg.conf this did not happen. When I get the chance I will try to look at the differences between the xorg.conf files to see if there is a pattern.

Supiik, could you attach your xorg.conf file? It's found here:
/etc/X11/xorg.conf

I compared my (messy but working) Xorg.conf to Xorg.conf.failsafe
The key difference appears to be this one:

InputDevice "Configured Mouse" "CorePointer" (working)
vs
InputDevice "Configured Mouse" (failsafe)

Hmm, I was going to triage it but apparently there's no TRIAGED option.

In any case, for me this is 100% reproducible:

To avoid the bug: InputDevice "Configured Mouse" "CorePointer"
To trigger it: InputDevice "Configured Mouse"

Hello alexrudd,

that's it. It helps. I did exactly same as you did - exchanged Configured Mouse to CorePointer
and it works.

Thank a lot. I see you are also a mouse buff.

Please attach your xorg.conf. Your description of the change is confusing.

@supiik: I just got lucky when spotting the difference. Glad it worked for you, though!

@Timo Aaltonen: I don't have access to my Linux partition right now, but the line I gave is in the ServerLayout section. The diff would look something like this:

Section "ServerLayout"
__Identifier "name"
__Screen "screen-id"
__ ...
++InputDevice "Configured Mouse" "CorePointer"
- - InputDevice "Configured Mouse"
__ ...
__options
EndSection

hi to all,

sorry I was little bit busy during morning.

Original xorg.conf:

Section "InputDevice"
        Identifier "Configured Mouse"
        Driver "mouse"
        Option "Emulate3Buttons" "true"
EndSection

it wasn't working with it.

I have changed it to:

Section "InputDevice"
        Identifier "CorePointer"
        Driver "mouse"
        Option "Emulate3Buttons" "true"
EndSection

After CRTL + ALR + BACKSPACE I have got woking mouse and this config:
Section "InputDevice"
        Identifier "Configured Mouse"
        Driver "mouse"
        Option "Emulate3Buttons" "true"
EndSection

Working xorg.conf is attached.

:) nice weekend

I had this problem as well when going from Gutsy to Hardy. Fortunately, adding "CorePointer" to the 'InputDevice "Configured Mouse" line in the ServerLayout section fixed it.

I would seriously like to know who marked this as Incomplete??

If anything, I would have marked it Triaged.

Hello. What type of PC is this issue on? We're working a similar issue under bug 197121, and I am able to reproduce the issues you describe as well. Would this per chance be on a dell pc?

Hello,

I have got Fujitsu Siemens AMILO Pro V3205.

Maybe stupid question, but who is responsible for status of this bug? Is it me, as a person who posted bug or is there some
server/bug administrator?

Because of complaining on inclomplete status I change it to confirmed. I hope I am doing correct action.

I'm on a Dell Latitude D620. It has an integrated trackpad as well as the little stick in the keyboard, and haven't noticed any problems with either.

As for the bug status, anyone can change it. If there is a developer or experienced triager involved, they will usually know best. However, it's certainly possible for mere bug reporters (like me) to figure out the correct status. Someone else will change it if there's a problem.

I had this problem on a PowerPC Mac Powerbook G4 using a Logitech USB mouse, but the addition of "CorePointer" to xorg.conf as described above fixed it. Thank you!! It was driving me crazy. Not every single click was interpreted as a double click, but nearly every one.

It was an upgrade some weeks ago on 8.04 that introduced the problem. The graphics card on this machine refreshes fairly slowly, and I wondered if this might have something to do with it - long periods with interrupts disabled, for example.

This has been fixed in hardy before the release. You need to either regenerate the xorg.conf (by running dexconf or dpkg-reconfigure xserver-xorg) or fix it like you've done here.

I disagree that the bug has been fixed in hardy before the release. I have downloaded the live CD two days ago, installed it, and I have it occurring right here all the time. It's totally frustrating me and driving me nuts actually.

Wow, and this bug is almost 8 months old judging by the date on the first comment...

I have the same problem on my dell m70 in 8.10
