It happens frequently, and it's driving me crazy: I'm using my touchpad and - for example - scroll through a list, and suddenly, the window will "jump" so that it's centered around my cursor, and it will follow my cursor!

Basicly, it acts as if I just did an ALT+Click (and drag), while I haven't touched the ALT key. And my cursor isn't positionned on the title bar!

As far as I can remember, it only happens on windows that are not maximized.

But there is worse (not sure if it's related): sometimes, when I double-click inside a window, the window will go from maximized to "normal" state (not minimized, just a small resizable window)!

I've also experienced a similar issue where orange "move" arrows would appear on windows... randomly! I managed to disable that through CCSM -> disable grab handles.

And finally, (again, not sure if it's related), my touchpad isn't always very responsive:

  • Sometimes, when I want to double-click, i need to 4x-click (very rapidly).

  • Sometimes, my cursor won't move for a second or two (I've already disabled "disable touchpad while typing")

  • Just like with the double-click issue... when I need to click something, I need to click 2/3 times before it works.

  • Every now and then, I can't "drag" stuff. Happens mainly when I want to resize window panels and such. The cursor will stop moving after my first attempt. It will start moving again (but not dragging!) after I smash my touchpad a few times to release my frustration. :-)

PS: I "click" with a tap on the touchpad, not with the actual left button.

There are no hardware issues: under windows, touchpad works perfectly.

EDIT: These days it seems like a CTRL+V is done when I move my finger over my touchpad!! I do NOT touch my keyboard when this happens! I think it mainly happens when I move (accidently or not) over the vertical scrolling zone of my touchpad (the zone to the right), but I never manage to actually reproduce the bug!

It's really annoying as it makes me waste time in situations where I quickly need to log on, write/code and log back off!

EDIT2: If it may be of any use, here's the output of synclient. It contains a lot of information, not sure if it's relevant: http://pastebin.com/N8K3tCqh

Would there maybe be a way to "import" those settings from windows?

I highly appreciate any suggestion.

Thanks a lot.

cool I just learned what alt + click does! :D –  Alvar Jan 20 '12 at 14:39
@Alvar My pleasure :D –  Mr. Pixel Jan 20 '12 at 14:58
Sounds like an issue with multi-touch, moving windows is supposed to happen when you click with three fingers at the same time. The problem is that disabling multitouch in untity is quite complex. –  Javier Rivera Jan 20 '12 at 15:09
It sounds like the ctrl-v behavior might be coming from the trackpad registering a middle click? This behavior will paste whatever is currently highlighted when you click the middle mouse button. This makes it sound like more of a trackpad issue than a software issue. What sort of laptop do you have, and do you know which drivers you are using? You might look into synclient if you're using a Synaptics touchpad. It can make things better and also show you what is actually going on when you touch it. This website might help you out too: help.ubuntu.com/community/SynapticsTouchpad –  jat255 Mar 18 '12 at 23:23
@Mr.Pixel, I should have been a little clearer. I meant that is sounds like it's more of an issue with the touchpad drivers than with a window manager or something like that. synclient is good for showing you what's currently registering on your touchpad, and can change settings for you as long as you follow the specs –  jat255 Mar 19 '12 at 22:26
