Mouse is stuck in drag mode (hand icon). Cannot click anything other than the top bar. Restarting doesnt fix it!

Question

My main account has an issue that it is constantly stuck in the drag mode (hand icon). Whenever I click anything other than the top menu it produces a hand icon and starts to drag it. I can even now click Conky widgets and drag them around the screen which I couldn't do before.

I was using the tweak tool at the time but I don't think I changed anything that would do this.

I have tried to restart the PC but it persists. However, the guest account works just fine. Any ideas on how I can fix this?

UPDATE: I have found the cause of the issue. It can be reproduced in the Guest account by opening tweak tool and going to "Windows" -> "Window Action Key" and setting the value to "Disabled". Is there any way I can set this value back to "Alt" by using the terminal and fixing my main account?

Solution 1

In my case I knew which program had caused the mouse cursor to 'freeze up'. I was using Archive Manager to drag and drop an image out of a zip file when I got the hand icon. Tried the other answers here without luck.

What worked for me was Alt-Tabbing to activate the application then press Alt-F4 to close the program window. Once the window closed, my mouse cursor returned to normal.

Solution 2

I fixed this myself by changing the setting in the terminal.

Open a new terminal with CTRL + Alt + T and enter:

gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier "'<Alt>'"
