I'm using elementary OS Freya 0.3.1 and would like to disable compositing while gaming. I'm playing CSGO (Linux port, not Windows version using Wine) and unlike on my Windows 10, it's lagging a lot. I would also like to disable hotcorners while in fullscreen gaming, as it goes into multitasking view randomly.
You can create a script to launch the game that disable hot corners before launching game then enable them back after closing the game.
#!/usr/bin/bash # Make backup of the settings dconf dump /org/pantheon/desktop/gala/behavior/ > ~/.hotcorner.dconf # Disable hot corner (just reset,as they are disabled by default) dconf reset /org/pantheon/desktop/gala/behavior/hotcorner-topright dconf reset /org/pantheon/desktop/gala/behavior/hotcorner-topleft dconf reset /org/pantheon/desktop/gala/behavior/hotcorner-bottomright dconf reset /org/pantheon/desktop/gala/behavior/hotcorner-bottomleft # Launch the game putyourgamecommandhere # Load back your hot corner settings dconf load /org/pantheon/desktop/gala/behavior/ < ~/.hotcorner.dconf
