I started to have problems with my Ubuntu application switcher (Alt +  Tab) this morning. When I press Alt +  Tab, not only one, but two application switchers show up. Last night I customized some stuff using the Unity Tweak Tool. I thought I didn't touch the application switcher. So now it looks like this:

I have two Alt+Tab window switchers. It's super confusing to try to use them. This screenshot shows it pretty well:    How can I get back to the regular switcher (the one in the background)? I'm guessing the one in the front is the older switcher. It seems the current behavior is that both switchers are functioning, but the one on top get's the "last word." So the selected window in the bottom switcher will be second to the top, while the one in the top switcher will be in front.  Background:    I lost Unity and finally got it back, after trying a lot of things. What finally worked was solution #1 from :    sudo rm -fr ~/.cache/compizconfig-1 sudo rm -fr ~/.compiz   Shortly before Unity disappeared (possibly the previous time the computer was on) I ran sudo apt-get dist-upgrade, which I am suspecting may have caused the problem.  What I've tried: sudo apt-get install --reinstall compiz and then log out.

In Ubuntu 14.04, when you hold Alt and click a window, you can drag it around.  As I understand, you used to be able to disable it through gconf, but Unity doesn't read settings from here any more (hence not being able to change where the window buttons are any more).  There's no setting for this by default, and I can't find anything in Unity Tweak Tool either.  Is there anyway to disable Alt+click window movement in 14.04?

I often use the Cmd+Tab shortcut to switch between different applications (for example: Xcode and Google Chrome), but is there a shortcut to switch between different windows of the same application (for example, from one window in Google Chrome, to another)?

In Gnome, we have applications grouped up based on their type (like - games, accessories, et al). But in Unity, we need to manually type in the Unity to get the App.  Is there any keyword/utility to display the applications in GUI?  Ubuntu Version : 14.04 Hardware : Dell Inspiron 3437

I'm looking forward to emulate the behavior of OS X Dock Stacks so that I can have, for instance, one stack for browsers and another one for IDES. People at ask ubuntu are doing a lot of cleaver stuff with custom Launchers and Quicklists (see ). So has anyone figured out how to have stacks in Unity? Anything fancier than a static Quicklist over a dummy folder icon?

Is it possible to have 2 unity launchers? One on the Left and one on the Right. In my thoughts, the Left one (The Default) would have the normal stuff that i use everyday. The Right side would have additional stuff that i might use like wine programs or to show the recent documents. Just some ideas to my reason to having 2 panels. Is it possible/optional?

I recently installed Ubuntu 17.10, and when I tried to set my keyboard layout to change with alt+shift, I hit a . There is  which works, but then it creates an unwanted behaviour on Firefox (perhaps other programs as well).   After setting alt+shift through gnome-tweak-tool as the combination to change language, whenever this combination is pressed within Firefox, it triggers a toggle that Firefox uses to show/hide the Menu Bar (with File/Edit/View etc.), and 'focus' is taken away from wherever the cursor was.   It's very frustrating, because one has to go and click again at the cursor.  The only solution I found was to permanently enable Menu Bar in Firefox because then alt doesn't do anything and I can use it to change languages. But I don't want to have Menu Bar on top always.  I hope you can understand what I'm trying to explain.  Any thoughts?

Can someone tell me how I can get an overview of all the open windows? Like htting ctrl+s that shows all the desktops, but for the open applications?  Right now when I hit Alt+Tab it shows quite small tiles in the middle of the screen, is it possible to have all the windows fill all the screens? (Kind of like expose in OSX)  I have compiz installed, and "static application switcher" selected, but this doesn't have the result I'm looking for (and neither does "Application switcher".  Any ideas?

I have installed Ubuntu 14.04 and I think that I have found a bug. When I open terminal and  go to edit profile preferences I get a rectangle with a cross on the title bar. It happened with other applications too. Here are the screen shots:

The latest updates (4/1/2018) make my laptop constantly crash the GUI/Unity:  (Intel Pentium su4100 processor)  syslog:  Jan  5 11:38:53 1810 kernel: [ 1850.327738] compiz[11911]: segfault at 0 ip 00007f6c7baf0c16 sp 00007ffd5ec71c60 error 4 in i965_dri.so[7f6c7b513000+82d000]   After login I end up with an empty desktop, just a wallpaper, GUI/Unity are in a crash loop:   No panel.  No dash.  Can't start a program. Launcher disappears. Sidebar disappears. System crash. Windows key not working. The key combination Alt+Tab not working.   Simply, the computer is not usable. Same for guest login. The only thing working: open up a terminal CTRL+ALT+T to examine log files.  I somehow forced  to let me log in and file the bug, but still lots of problems:   Dash not working Alt+Tab not working Sometimes windows all disappear for a few seconds     Any ideas for a solution or workaround?   UPDATE     If you have the same/ very similar problems, follow the link to my    report and mark there that you're affected too. Or file your own. Please leave a comment   if you wish, or upvote - this is a nasty problem - but an answer should   offer a fix or a workaround so users can use their computer again.    Without , Ubuntu can't fix issues.

I recently upgraded to Ubuntu 13.10, with the new keyboard handling system. The little "switch keyboard" option does not let me set it to Alt+Shift. How can I get this keyboard binding, as I have absolutely no interest in using the Mac-esque Super+Space combo?

Is it possible to remove "Show Desktop" from the Alt+Tab application switcher?

When using task switching in the default graphical mode of Ubuntu 12.04, if they are multiple windows of the same kind, eg. multiple Terminal windows, you can see them all together and select which one you want.    My problem is that the order of these windows is constantly changed. It follows the "last used" order. I want them in a fix order always; how can I do it?

Enabling Bias alt-tab sorting to prefer windows on the current viewport as described  made no difference. How can I get back the exact same behavior as 11.04, so that alt-tab only switches between windows on the current workspace?  Simply disabling the alt-tab and shift-alt-tab keybindings on the unity switcher seems to have helped, but it still switches workspaces on me sometimes.  For example, if I give a terminal window focus then press alt-tab, it switches to another terminal window on any workspace before trying to switch on the same workspace. Also, the Unity switcher still shows up when I alt-tab then hold alt even though I removed its alt-tab keybinding.

I would like to switch between windows using the scroll wheel of the mouse over each app icon in Ubuntu dock, as we could do in Unity, but apparently this doesn't work in Ubuntu 17.10. Is there a way to enable it?   Related:

I'm using Ubuntu 11.10 with Unity and would like to switch between workspaces with a keyboard shortcut.   Is there any way to achieve this?

As of Ubuntu 16.04, Some emacs key combinations involving Ctrl and Alt conflict with the keyboard shortcuts in Ubuntu. One way to fix this is to go to System settings > keyboards > shortcuts and disable / change all the ones that conflict.  A similar question was .  However, there are some shortcuts that are not in that setting. For example, in emacs, Alt-` (backtick key) is used to open the emacs menu. However, in Ubuntu, it opens up a window switcher with a preview. Similarly, Alt-Tab toggles the switcher. These shortcut keys are not in System settings > keyboards at all.  How can the windows-switching shortcuts be remapped so that they don't interfere with emacs?
