I've run openSUSE on mine as described here:
http://en.opensuse.org/HCL:ARMChromebook
There's an image you can put on an SD card, then with the Chomebook in
developer mode[1], you boot off the SD card (have to hit CTRL-U at each
boot to do this). This means you can have a play without trashing or
otherwise repartitioning the SSD.
Last time I tried this, *something* didn't work (might have been not
waking from screensaver? I forget exactly), and I never got around to
figuring out what it was. This may well have since been fixed.
I ultimately ended up just running my Chromebook in regular ChromeOS
mode, as I'm really only using the thing occasionally as a a slightly
glorified web browser, and I got sick of it whining loudly at me on
every boot about the possible doom associated with being in developer mode.

Does any have an idea why I can connect the the work Wifi with Windows and
Ipad but Linux will not establish a connection. It seems to be perfectly
normal with WPA2 encryption.
I don't know where to look to solve this one there is nothing wrong with
the Wifi on the computer it connects just fine at home or at friends.

Hi all,
I'm trying to set up CUPS on a Debian Sid system.
I have the latest CUPS available via apt-get (1.7.1-6).
When I try to browse to the web interface (http://192.168.1.4:631 and
https://192.168.1.4:631), I'm getting a HTTP 403 Forbidden error.
I am having trouble finding anything which explain how to fix this.
Everything I've found so far seems to assume that the web interface will
"just work".
The server running CUPS has no GUI, so I can't test to see if the web
interface works there or not.
The changes to the default Debian configuration file:
LogLevel debug
#Listen localhost:631
#Listen /var/run/cups/cups.sock
Port 631
#<Location /admin>
# Order allow,deny
#</Location>
Any assistance will be greatly appreciated.
Regards,
Tim Lyth
Hi All,
I've got a 3.9 GB video file that I want to reduce significantly in size.
I noticed the Nautilus >> Properties >> Audio/Video Properties on this
file said the resolution was 1920 by 1080.
So I searched the web and found the suggestion to use mencoder -- which
was already installed in my system.
Set the resolution to 960 x 540 and expected an output file of a bit
more than 1/4 of the original file size.
Quite surprised to see that the output increased in size to 4.8 GB!
Any hints on how I can resize the resulting file down to about a quarter
of the original?
I've got AVIDemux, GStreamer plugins and codecs, movieplayer, smplayer,
pitivi, transmageddon, VLC media player, and apparently mencoder.
Thanks a lot,
Carl

Here's the command I gave:
> mencoder TWYDS1.mkv -vf scale=960:540 -oac pcm -ovc copy -o TWYDS2.mkv

Hi,
Samsung have had an ARM-based laptop for a while, sold as a Chromebook.
(ie. with an Android-like Linux kernel and the Chrome browser as the whole OS)
The little ARM cpu means the laptop doesn't need much power and can
run for quite a while, despite being lightweight and cheap with a
small battery.
I was wondering how it'd go running a full version of Linux; just
running a bunch of terminal emulators more of the time, and maybe
Chromium from time to time.
I've heard of people managing to get Ubuntu or other linux variants
installed, but I wondered if anyone here has done it? Was it worth the
trouble?
Cheers,
Toby

Hi,
I want to try Linux Containers (LVC 1.0 is out) and BTRFS (in a way I
use FreeBSD and Jails and ZFS).
I want to use filesystem cloning (at the moment under FreeBSD "cd
/usr/src; make buildworld; make distribution; zfs snapshot; zfs clone")
I also want to have a small but useful userland.. I am thinking of a
"minimalist" Debian installation but other ideas are welcome too.
Do you have good advice to achieve this? (TW: I am not a huge Busybox
fan, the tools always seem to miss the one option I want to use.. so,
no scaled down tools, just a good set of "standard tools")
I do not know about the memory footstep and minimal requirements of
BTRFS and ZFS under Linux, comments and advice is welcome as well.
Thanks
Peter
A client is looking for a new embedded system. Their current systems have a
500MHz AMD Geode CPU (which provides a lot more power than they need). A
randomly selected system has the following output of "free". So any of the
bigger embedded systems (which seem to have 256M+) will do, but the small ones
with 32M will be out of the question and even 64M probably won't do.
total used free shared buffers cached
Mem: 997864 46248 951616 0 7284 21388
-/+ buffers/cache: 17576 980288
Swap: 0 0 0
I'd like to run a fairly stock Debian installation. I guess that a system
with 32M of storage would do if I configured it to use a micro-SD card for
main storage. The device would need to support at least 2G of storage,
preferrably 8G or 16G.
Digital IO ports are required as well as a serial port. I guess it's possible
to use DTR/DSR and RTS/CTS on a second serial port if a board does everything
else right, only 2 digital outputs are needed.
The current systems have 2 ethernet ports, 1 for Internet access and 1 for
debugging, we could survive with only 1 port if everything else is good.
The device needs to be designed for high temperatures, 70C operating
temperature will do.
Basically it would be pretty ideal if I could get something like a Samsung
Galaxy S that's rated for 70C and has at least 1 Ethernet port, USB, and
digital IO.
Any suggestions?

Hi,
I have a little ARM board (radxa rock) which unfortunately only has
support in a modified 3.0.36 kernel. Maybe the Chinese manufacturer
will honour the GPL at some point and release source code, but for the
moment it's all we've got :/
Unfortunately, I have some USB webcams that aren't support in that old
a kernel; I know they're supported by 3.4, possibly even earlier.
Has anyone tried backporting the uvcvideo and supporting video4linux
modules? Just wondering if it's likely to go well or if I'll be
wasting my time.
Cheers,
Toby
The attached script can be used to get files from the Olive Tree FTP server in
a fairly default configuration on an Android phone. Consider it as an example
of what can be done with expect.
The script takes a single command line parameter of the IP address of the
phone. The user-name and password are the default for the Olive Tree FTP
server.

/data 10.1.2.3(rw,sync,no_subtree_check,no_root_squash)
I have the above in /etc/exports, root on the NFS client can't run chown, it gets
EINVAL. Both client and server are running Debian/Wheezy but the server has
kernel 3.11 from Debian/Unstable (for BTRFS).
I don't think it's a BTRFS issue as I have another BTRFS NFS server that works
well.
Any suggestions as to what I should investigate? Please include the "obvious"
things as I probably missed something that's supposed to be obvious.
