Disabling "SHOW LIVE PREVIEWS OF WINDOWS IN THE SWITCHER" may work for show desktop, but I don't use it so I can't tell. However it doesn't work on scale's hot corner on reboot. You still have to log out and then log in again for the corner to activate, but then you may as well restart Unity, it is faster (without disabling "show live preview" logout and login doesn't work at all)
My previous workaround a few months ago doesn't seem to work anymore, mostly lilkely thanks to some updates along the way (tested with different hard drives). https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/858845/comments/59 Half of the times unity just doesn't start properly and have to manually shut down, on reboot it goes through disk checking and what not. It seems that somehow for whatever reason the file system get corrupted if restarting Unity doesn't complete successfully at start up (manually restarting after login is OK) Have reformatted and restore from last working image many times since last night. Well if they don't fix something at least don't screw it up with updates, now I have no idea which update is the culprit. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1305438 Title: hot corners stop working time to time Status in “compiz” package in Ubuntu: Confirmed Status in “unity” package in Ubuntu: Invalid Bug description: After upgrading to ubuntu 14.04, time to time hot corners stop working.
