Desktop Effects prevents any window from stretching across dual monitors

Does this happen with any window, or just gnome-terminal? It sounds more likely to be a WM issue rather than a gnome-terminal one

It happens with any windows. I tried xterm, gnome-terminal, xfce-terminal, firefox, gimp.

Same problem here. When using 9.10 with Desktop effects enabled I cannot resize any window beyond the current monitor. Only way is to resize it first resize it in the current window to the appropriate size and then move across the monitor.

I have the same problem also.

Fresh install.
Applied all updates
Restarted
Enabled Nvidia v180 Driver
Configured my Nvidia Quadro card with Twinview Dual monitors
Turned on Desktop Effects
Now unable to stretch any window across the two monitors.

I also have this problem. Apparently it's actually intended functionality, but I just find it annoying and stupid. I mean it's reasonable to only maximize to a single screen, but when resizing, it just refuses to do something that I explicitly request. That's just wrong. That being said, I would also like a "maximize across all screens" button sometimes.

Is anybody at ubuntu looking at this, or do we have to complain to compiz upstream?

To all subscribers with nvidia cards: Have you tried turning xinerama hints off? I remember that used to be possible in the nvidia drivers in the xorg.conf somehow. That way your window manager will not even know that you're runnning two screens, it will just think you have one big one with a weird geometry. That will of course break other things, but would probably work around this issue if it's imoprtant to you. I can't test it myself since I'm on ATI at the moment and don't know how to do it there.

Experiencing the same issue
10.04
64bit
ATI x1650 card
Dual Monitors

There is no way that this is intended. When looking at enormous spreadsheets, or working with very large complex graphics I need to be able to span the monitors. And I imagine others have this need also. Coming from a windows world I was very surprised that this did not just work with Ubuntu.

If providing logs or other things would help please let me know, I will help if I can.

You will see workarounds/solutions, and a reason for this.

Workarounds:
- Resize your windows with alt + F8
- Resize your windows with alt + middle click
- Disable Compiz

Reason:
Resizing by dragging window borders is limited to work area by Compiz to prevent window edges from becoming inaccessible while resizing by going behind panels or beyond screen edges. To handle this issue, Metacity instead uses snapping during resize, which Compiz 0.8.4 lacks.

Hope that helps.

even if there are technical reasons for the """feature""" - it needs to be fixed such that the user action (resizing the window with the mouse) is carried out without requiring a special command when it goes beyond the screen. i have seen new graphics cards which allow 6 monitors! anybody having used two monitors when coding will not go back and the current """feature""" is in the way of flexible use. i have turned compiz off, but not everybody will be willing to do this.

For me this issue no longer exists in Ubuntu 11.04. I'm using the Unity desktop environment.
