I didn’t have problems with Compiz ; to fix the cursor theme I did install
LXApp… with Synaptic ; tearings are very rare ; but when I want use
something that uses flash , it’s like fireworks . I select HTML5 Player ,
but somethings need flash ; it’s updated , Ubuntu Restricted are installed ,
but …
So, I have seen compiz --replace crash the very first time it is invoked. If you run compiz --replace again immediately everything works correctly from that point on.
I have found that if I use the ini backend, rather than gsettings, this initial compiz doesn’t happen but has the side effect of not being able to edit the compiz profile 
Can you post just the sections of your compiz profile for hot corners so I can take a look?
Absolutely. Here’s the stuff that mentions corners:
s0_top_left_corner_action = 4
s0_top_edge_action = 10
s0_top_right_corner_action = 6
s0_left_edge_action = 4
s0_right_edge_action = 6
s0_bottom_left_corner_action = 4
s0_bottom_edge_action = 0
s0_bottom_right_corner_action = 6
Just in case, I’m tacking these on… not 100% sure what you want to see, and the other subsections mention the edges set or the initiation edge. I didn’t change anything from default, other than setting the corners to use of course.
Here’s the expo and scale sections:

s0_expo_key = s

Well… I wanted to test this when I got this message:

So I guess, compiz doesn’t work on my computer 
So I ignored the warning and compiz is working, but I can only set one virtual desktop. Although in Marco I have 4. It referts back to 1 whenever I start compiz. How can I set the number of Virtual Desktops?
I am on UM 14.04.
Yeah, the warning is to keep the tourists out
Well, I have defined 4 virtual desktop set in the Compiz profile and on my system I see all 4 when running Compiz. So, that is odd.
I’ve also updated MATE Tweak today so that when you request a switch to Compiz it will check if Compiz is running, if not, it will try Compiz again and then fall back to Marco if Compiz is not running.

Is your intention to launch 15.04 tomorrow ? These modifications are there ?
I only had one virtual desktop by default as well. When I get home I’ll look and see where I enabled it. General Settings I think.
I think this was it:
I imagine it will be released in April when Ubuntu 15.04 is released. The version number is year.month.
Compiz is working for me on an Acer C720P (Chromebook)! 
Great job, Wimpy!

Still solid for me… everything looks good!
Everything seems to be working good for me after 24 hours. I noticed that someone had some trouble with an AMD graphics card. I have an AMD graphics card and have the latest proprietary drivers installed from AMD’s website.
The Ubuntu 15.04 Alpha 2 version is expected to 22/01
Sorry, I thought you meant final release.

I’ll be making a new Compiz package today. I’ll need to figure out how to obliterate your existing compiz settings to ensure the new profile is correctly enabled and imported.
Basically, the gsettings back is not working reliably. On the very first (ever) invocation of compiz --replace it is likely to crash. Also not all the MATE Compiz profile settings are correctly imported to gsettings, which is why some of you have reported inconsistent configurations.
The solution seems to be switching to the ini backend but has the drawback that if you’ve previously used the same profile name under gsettings changing stuff in compiz-settings-manager can cause compiz to crash.
So I need to figure out how to completely trash the compiz settings from gsettings for those of you who started testing early. Thanks for that BTW

Don’t worry about me Martin. I have re-written my machine with Precise Mate and have also made a Clonzilla image of it. So, I am happy to test out the new Compiz package as soon as you have it ready.
I suspect that’s what I just dist-upgraded to
I rebooted after the update and had the “desktop cube effect” and 4 virtual desktops instead of the two. My hotcorners had also been reset to the default “off”.
Looks like a new config to me 
Working smooth so far BTW.

That’s very gracious of you @stevecook172001but that isn’t how I do things
If you’ve encountered a problem, so will others. So, I’ll try and fix what I can. That said, I won’t be back porting my Compiz stuff to Precise 
No worries… and no, don’t try that when you get home… just do an update.
The packages that Martin pushed earlier will blow out your config anyway
