Package: xbase-clients
Version: 4.3.0.dfsg.1-7
Severity: minor

The default mouse acceleration on a new X install is abysmal.  Please
document and make default the xset options to make it not suck.  See

Thanks,

That sounds pretty much like an upstream issue to me.  If you still think
the defaults are wrong, I suggest you get them changed upstream in
X.Org, and the Debian X packages will follow.  For now, I'm closing this
bug; feel free to reopen it and reassign against the xserver-xorg-core
package if you think it should stay open.

Cheers,
Julien
