So I have a fresh install of Centos 7 Desktop version. It uses gnome 3.8 and I have multiple monitors. When I go left to right with my mouse on the top portion of the screen, it shows me all my open windows, side by side. I can also hit the windows (Overview Mode) button to see the same effect. It's distracting me and making me waste time and my train of thought.
How can I disable this feature?
I checked the tweak tool and nothing. When I tried googling it, everyone says is a CompizConfig setting. Well I don't have a compiz config tool.
I JUST figured this out for CentOS Linux release 7.5.1804, it's Oct 6, 2018 today.
So this has been made vastly easier by the people who make CentOS.
yum install gnome-tweak-tool gnome-shell-extension-no-hot-corner
Then, you should find it in your Applications -> Utilities -> Tweak Tool -> Extensions -> "No topleft hot corner". If the tweak tool is there but the extension is not, try rebooting. I needed to reboot, but the tutorial that I found said I shouldn't need to.
If youu don't find "No topleft hot corner" in Extensions section of Tweak Tool, Click "Get More Extensions" and search for "No topleft hot corner". Download it and add it in Extensions section and you are done.
