Hi @Nunud,
I’ve never used corners but took a look at that video and setup his first “Show Desktop” exactly as he did and it works fine. Verified all 4 corners work, too.
Some possible differences:
- I’m running the 16.04 PPA for Mate 1.14:
MATE Desktop 1.14 for Ubuntu MATE 16.04 is available now
This is quite an install to commit to, be warned. - I did NOT install the compiz-plugins-extra package.
- I turn off a lot of default stuff, change the switcher, and enable the cube. I use compiz mostly for the Zoom.
Make sure “Mouse position polling” is on. I’m sure it needs it and should force it on but you never know.
