Because they seem to be OK, e.g. transfer speed when using
rsync is what is was before. Anyway the slowest part in the
link is probably the wireless access point anyway.

Meanwhile I installed nouveau. The only difference I notice
is that now the 'visual bell' in xterm has become very slow
as well (to the point of being unusable), also locally.

There are some other things I noticed:
(with either nv or nouveau)

I'm pretty sure this is installed.

qjackctl is a qt4 app.
