I recently installed Ubuntu 18.04. Previously in GNOME 3, the minimize, maximize, and close buttons never appeared on any of my applications, such as Chromium Browser and Emacs. These buttons annoy me because I am used to  clicking Alt+Space.   How do I remove these buttons from Ubuntu 18.04?

(Ubuntu 13.04 with GNOME Shell, upgraded, GNOME version 3.8) Recently, I upgraded Ubuntu to 13.04. the default desktop is gnome-shell. Except Nautilus, other software border doesn't disappear when I make them to be maximized. I checked the problem for these software:  LibreOffice Firefox Rhythmbox thunderbird GNOME-Terminal  On the other hand there are three bars on maximized mode:  GNOME Shell panel  Title-bar for software which contains - + x (minimise, maximise, close) buttons.  Software menu-bar  Number &quot;2&quot; is extra. Is a package missing?

Please could you tell me where can I find the File Manager Preferences in Ubuntu ... (now for 16:04 LTS).  The menu bar has disappeared from Nautilus, as also have the resize handles and the top-bar right-click menu (except for 'Close').  The window gets a little smaller every time I open it, it's gradually disappearing and I can't presently correct it.  I'm using Gnome not Unity, so the fixes for unity don't work.  I would have preferred to add these observations as comments, but I still have too few reputations to do that, so have to ask a new copy of the same question instead.

I just went from 18.10 to 19.04 and the desktop icons and shortcuts are there but they are too large. Previously I could decrease their size from nautilus but now they seem to not respond to that and as far as I know, the desktop icons are no longer under nautilus.  I was wondering if there is a way to decrease the size of the icons already on my desktop instead of installing some new extension to create new icons and then resize them.

How can I get the middle mouse button to behave correctly in Ubuntu? Clicking the middle button does not show the arrow which allows me to scroll the page by moving the mouse.  Information:   Firefox 3.6.8 Mouse: Microsoft Intellimouse Explorer 3.0

Is there a way to the switch gnome-shell window buttons to the left? I've gotten so used to them being on the left that them being on the right has thrown me way off.  (gnome shell has them defaulted to the right corner)

I know how to Hide (Cmd+H) or Minimize (Cmd+M) a focused window in OS X, but I can't find a keyboard shortcut or even a menu item to restore, unhide, unminimize, or otherwise show a window that I've hidden or minimized.  Anyone have a suggestion?

Just moved from Unity to GNOME with the update to Ubuntu 17.10. There is a HUGE amount of wasted space at the top of the screen, when an application is open.  Evolution and Firefox both have four "bars" with 90% of each empty. Unity, to its credit was able to blend / mix these horizontal bars so there was only one / two.      Four is way too much. If this is GNOME I may carry on with Unity for the next six months.  Can anybody suggest a tweak/change/fix for this?

I am migrating from Unity to GNOME. One item I am missing is a "Show desktop" button (aka "minimise all windows") in the dash. How can I add this functionality to the GNOME dash (or Ubuntu dock in Ubuntu 17.10 and later), even if it means making a custom .desktop file?  (I know that I can use the Ctrl + Super + D   and that I can install , but I specifically want a button in the dash.)

Unlike Windows, you cannot maximize a window in Mac with a click of the button. The little green (+) button next to the red and yellow buttons at the left of the windows does some strange stuff sometimes when you click it and doesn't do the expected operations.  How would you fully maximize a window on a Mac?

When I move a window close to the top, it snaps to maximum size. I am using Ubuntu 18.04, GNOME 3.28.2.    How do I disable that? I searched about six months ago, no way to disable back then.  1/5/19 Yes, solved!  Thank you!   These two worked on my Ubuntu 18.04     gsettings set org.gnome.mutter edge-tiling false   dconf-editor   These did not work     GNOME Tweaks  (disable "Edge Tiling" not available)   gsettings set org.gnome.shell.overrides edge-tiling false    Thank you Kulfy, Hamza Saeed, vanadium, PRATAP.

How can I minimize a single window in Ubuntu?  I have looked in the keyboard shortcuts and there is a maximize windows but there isn't a minimize windows.

I have been searching for a way to disable the "hot corner" feature of the Activities button in Gnome Shell. I would prefer it to require a click such that I don't keep accidentally activating it upon mouse over.

I love how you can resize windows by pressing alt+middle-mouse-button and drag.  Though now I got a mouse which doesn't support pressing the middle mouse button..   How do I do to change the combination from alt+middle-mouse-button to alt+right-mouse-button?  (On Ubuntu 11.04 with unity)

I just upgraded to 18.04 (with GNOME 3.28) from 16.04. I am using gnome-shell, gnome-ubuntu-desktop. After upgrading the icon size on desktop are very large.  I am unable to find my option to decrease the size in preferences. How do I decrease it?

I am using Ubuntu 18.04. I realize with GNOME, or its extensions, I can do things like hide the title bar. However, I want to hide the title bar and still see the windows management icons like on Mac OS and Windows.   Is this possible?

that deals with the different behaviour of the fullscreen button in the window bar. There, it is shown that by doing:  ⌥ + ⇧ + Click on green or outer right icon (plus icon)  I can maximize a window in both width and height to the current screen.  Now I am wondering if I can make this behaviour standard just by clicking the icon. For an extra bonus, I wonder if there is a keyboard shortcut to achieve the same thing.

I want to tell compiz, metacity, the gnome-terminal or whoever is in charge to open the terminal window maximized by default.  How can I do that?  EDIT for the future: most of the answers were upvoted in older ubuntu versions, since 17.10 and on the most upvoted solutions do not work.
