In Ubuntu 18.04, using Gnome Tweak tool there's a way to disable the Activities hot corner. I have a multi-monitor setup, so having this feature on is extremely annoying. Anyway... After a couple of minutes (sometimes just seconds) the corner seems to re-enable itself. I check on the setting on Gnome Tweak and it's indeed disable. Here's a gif of the situation:

It seems that the problem happens after gnome-shell is restarted. Seems like this might be a bug, which if confirmed I will report it.

Any ideas on how can I prevent this from happening?

  • Try to disable it forcefully using an extension (see this: askubuntu.com/q/984705/480481).

  • Oh, sorry, I forgot to mention that I have used a couple of extension and I still get the same behavior

  • I've got this behaviour as well. Very strange. Seems to re-activate every few hours

It appears that the Dash to Panel extension also leaves this setting permanently enabled. If you are using this, you will have to pull a commit this is AFTER May 10th, 2019, or it will be broken. As of today, there has not been a release since March, so you'll have to build master yourself.

If this is happening to anyone who isn't using that extension, here is another solution: simply add a job to crontab to reset it every 5 minutes.

 */5 * * * * gsettings set org.gnome.shell enable-hot-corners false

Despite the value never actually being true, this will still cause the gnome shell to refresh, and remember your settings.
