I didn't read all of these posts, but in my case I found a solution.

I changed graphic driver to the second option, and now it's very fast. Maybe some of you with this trouble can change a graphic driver?

[Bug 299330] Re: Alt+Tab - switching applications delay. slow
The original bug report mentions a latency of 0.5 seconds, so note that this is NOT a hugely obvious bug - nevertheless it is one of the most important things to be responsive on the entire desktop. UI responsiveness is usually measured in milliseconds, a full second is an eternity for a keystroke response. I too see this bug in Ubuntu 10.10 using an Nvidia 240 GT (driver version 260.19.06), with metacity compositing enabled. Latency is near- zero when compositing is disabled. Latency encountered when using Compiz should probably not be discussed in this bug report; compiz is a totally separate code path with unique issues. Naive observation suggests that the WM is waiting for the window thumbnails to render before it draws the alt-tab window for the first time. It's vastly preferable for the alt-tab window to appear immediately, with whatever representation of the windows it can provide (icon + name) until the window thumbnail is ready to display. Aside from more complex code, are there any reasons this shouldn't be the intended behavior? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/299330 Title: Alt+Tab - switching applications delay. slow -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 299330] Re: Alt+Tab - switching applications delay. slow
Hi, to confirm, I'm still having the issue since a year ago, even on the latest ubuntu. I observe 3 or 4 seconds (more with more open windows) before the alt-tab window appears. During this time, the system is not responsive, and thus I lost the habit of using alt-tab, using the mouse to switch app focus This only happens when using compositing with metacity. While we could expect that compositing should not be used with metacity (software rendering), compiz has issues with multi-monitors, and compositing is necessary for several media applications. As stated in the previous message, changing the order of the alt-tab treatment would be best. A simpler fix would be to be able to modify thumbnails options, such as turning it off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/299330 Title: Alt+Tab - switching applications delay. slow -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm having this bug in Lucid. Compiz doesn't work with dual screen on my computer so I have to use metacity instead. Of course, turning compositing off is out of option.

[Bug 299330] Re: Alt+Tab - switching applications delay. slow
This bug/problem is of hard reproduction. I have two computers here, exactly the same specs, and one has a slow Alt+Tab window switching, and the other one has no problems in this operation. I did some tests with Compiz and the problem just don't seem to be with the desktop effects. I also disabled all the resources I could imagine to cause this problem, and no success. Well, switching through opened windows it's being really painful for me, and I really hope that you guys can find out what's happening. -- Alt+Tab - switching applications delay. slow https://bugs.launchpad.net/bugs/299330 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I some times get this if I have a large number of windows open. I disabled visual effects. Problem went away. It said could not enable visual effects when I tried to re-enable visual effects. I closed some windows, including one which was frozen, and then it allowed me to re- enable desktop effects. Problem became less serious.

OK, to reproduce, run something like: for i in `yes | head -n 40` ; do (gwenview /usr/share/evolution/2.26/images/world_map-960.png ) ;done Then I get ~10 seconds for 10 alt-tabs.

[Bug 299330] Re: Alt+Tab - switching applications delay. slow
I believe this bug should be re-open, I'm using Ubuntu Jaunty 9.04. If I use the desktop effect under normal, it become annoying switcing back and forth between windows, I agree with Cristian, Ubuntu trys to show the applet switching between windows and it is just annoying and slow. If you switch you Desktop Effects to None, you get rid of that annoyance.

Hello, well, technically it's not a bug, only an area for improvement no delay and shift-alt-tab works in compiz, that's true the delay i'm reporting about is with plain GTK.
