Weelll Said Peter Goudman. Compiz Alone is destroying all the goodwill earned so far by Ubuntu. I am always ready to hit that reset button to get out of that black screen lockup happening quite often, specially when you have a lots of windows open. If you have any Docks(even plan is pretty bad these days). it is bound to happen more frequent. SO frustrating, that every now and then, I have to close Plank, then do a compiz --replace when the mouse starts getting sluggish. It is when the mouse starts getting Sluggish, that the BOD(Black Screen of Deatch) is coming soon to happen.
Every release of Ubuntu, comes with GUI glitches that are so disgusting in a day today work. I think after version 11.04, almost everything is messed up with Ubuntu. It looks as if Compiz development is more geared towards keeping Unity Happy and careless about any other DE. While XFCE is really great, Try Ubuntu Mate : I found it quite fast, sleek and awesome from the first look, and with at least 30+ including 25 odd Chrome(memory management sucks) windows, it was still rock stable, at least in my case. https://ubuntu-mate.org/ -- 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/1293384 Title: Compiz CPU usage dramatically increased in Ubuntu 14.04 Status in Compiz: Triaged Status in compiz package in Ubuntu: Triaged Bug description: It appears that the workload of low-level graphical operations used by compiz when, for example, moving windows has increased dramatically between Ubuntu 12.04 and Ubuntu 14.04. This might not be that visible when using high-end gpus, but should be clearly visible when using compiz on llvmpipe and to some-extent invalidates the approach of using compiz on top of llvmpipe as a fallback when no GPU is available: How to reproduce: 1) Use the unity-3d desktop in Ubuntu 14.04 on top of a non-accelerating Xorg driver like "modesetting". Move windows around. Note peak and average cpu-usage. How to verify compiz is the culprit: 1) copy /usr/bin/compiz from a Ubuntu 12.04 installation. Drop it in as /usr/bin/compiz on 14.04. Reboot. Perform the same window movement. CPU-usage should be substantially lower. This problem also affects VMs running on VMware ESX with a software- rendering GPU. Window movement becomes sluggish, which suggests that even with GPUs, compiz has increased the number of operations required to move windows.
