# Ubuntu – Disabling vsync in Unity/Mutter/Compiz

compizmutterunity

Yesterday I was still using Natty with Compiz. I had noticed that disabling Vsync in Compiz made dragging windows much more smooth and responsive (I don't mind the tearing).

I installed Ocelot this morning which seems to use Mutter by default (I may be wrong there, I'm still kind of lost). Dragging windows has the same sluggish feeling as with Compiz and Vsync enabled. So I was thinking I could try disabling Vsync.

Can vsync be disabled/enabled in Mutter?

$ps -ef | grep compiz | grep$USER
<myname>  3989  3908  5 12:14 ?        00:03:38 compiz
<myname>  4051  3989  0 12:15 ?        00:00:00 /bin/sh -c /usr/bin/compiz-decorator
<myname> 15409 15406  0 13:25 pts/0    00:00:00 grep compiz


So indeed I was confused. If I'm running Compiz I should manage to bend it to my will.
