# Disabling vsync in Unity/Mutter/Compiz?

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.

First, let's find out if you're running Unity 2D or 3D. Please run this in a terminal and add the output to your question. ps -ef | grep compiz | grep \$USER –  jrg Jan 2 '12 at 11:33
ummm - are you running gnome-shell or the unity interface? –  fossfreedom Jan 2 '12 at 11:35
Unity uses compiz not mutter. –  Javier Rivera Jan 2 '12 at 11:43
@fossdreedom I'm using the unity interface. –  Niriel Jan 2 '12 at 12:29
@Javier Rivera Good to know. I got confused. –  Niriel Jan 2 '12 at 12:31
