Maybe. The machine runs "Tubuntu 12.04", which is an Ubuntu bundle from
my employer. But I haven't seen other anomalies on that machine, and
most of the packages are native Ubuntu ones. The differences are mainly
user policy and alike.

I'll see whether I could find another Tubuntu machine, and cross-check
whether it is a hardware problem. The problem is that Tubuntu is not
widespread (managers are focussed on MS Windows, and they rule); I don't
know whom to ask here at Berlin. But there is a company-wide Tubuntu
mailing list ...

I'll check tomorrow more systematically.

Best regards, Michael.
