Public bug reported:
FSC Futro thinclients can be used as nettops, because high speed CompactFlash
cards have become reasonably cheap today. Operatingsystems can be installed
locally onto ConpactFlash-memory. The card used provides about the same
read-speed as gigabit ethernet would.
It was a chronical problem with this box, that intermittent boot-problems
occured, either when booted from cold condition or at warm-reboot. The system
hung somewhere near IRQ- and ACPI-initialisation. First I thought this might be
due to incorrect BIOS-settings, replaced the RAM, now I think, that there are
powersupply-incompatibilities between different models. There are two different
power-supply models available and incompatibilities may occurbetween systems,
please beware.
I chose the low-latency kernel variant for this box, i.e. installation was only
possible in expert-mode (from USB), during the process I selected the second
kernel-version offered (generic) and when it was done, it was possible to
install a low-latency kernel and remove the other. With debian I experienced
earlier, similar boot-problems with pae-kernels. So it is very positive, that
Ubuntu offers a wide variety of kernels with and without PAE, even a
realtime-version. There is not so much need to build a kernel-package yourself,
that matches the system.
512 MB of RAM are sufficient for Xubuntu for nettop-use. Hopefully it is
possible to upgrade to the next LTS-version 2014 without having to upgrade the
RAM-amount. The energy-consumption is very low, at a maximum of 21 Watts, so it
can also be used as a home-server, running most of the time, or as a client for
testing network-setups.
256 MB of RAM are insufficient for desktop-use, because even when using light
webbrowsers like midori and 'webbroser' epiphany, it is not possible to open
more than two or three tabs at the same times without making the system using
swap space, slowing it down to non-usability, also without swapping for light
applications it is slower, because there is lack of disk-cache, so even lighter
desktop-environments would be recommended.
In my opinion this privides avery good price-performance ratio, the boxes are
available in abundance in used or refurbished condition and quite affordable.
I changed /etc/default/grub and attach this file.
